CCAK Certificate of Cloud Auditing Knowledge Questions and Answers

According to the web search results, the most critical finding of an application security and DevOps audit would be that the application architecture and configurations did not consider security measures. This finding indicates a serious lack of security by design and security by default principles, which are essential for ensuring the confidentiality, integrity, and availability of the application and its data . If the application architecture and configurations are not secure, they could expose the application to various threats and vulnerabilities, such as unauthorized access, data breaches, denial-of-service attacks, injection attacks, cross-site scripting attacks, and others . This finding could also result in non-compliance with relevant security standards and regulations, such as ISO 27001, PCI DSS, GDPR, and others . Therefore, this finding should be addressed with high priority and urgency by implementing appropriate security measures and controls in the application architecture and configurations.

The other options are not as critical as option B. Option A is a moderate finding that indicates a lack of awareness and assessment of the global security standards specific to cloud, such as ISO 27017, ISO 27018, CSA CCM, NIST SP 800-53, and others . This finding could affect the security and compliance of the cloud services used by the application, but it does not directly impact the application itself. Option C is a severe finding that indicates a major incident that occurred at the cloud service provider level, such as a service interruption, breach, or loss of stored data. This finding could affect the availability, confidentiality, and integrity of the application and its data, but it is not caused by the application itself. Option D is a minor finding that indicates a lack of efficiency and consistency in integrating cloud compliance with regulatory requirements. This finding could affect the compliance posture of the application and its data, but it does not directly impact the security or functionality of the application. References:

 Effective operationalization of cloud security controls is highly dependent on the level of training and awareness among the staff who implement and manage these controls. Without proper understanding and awareness of security policies, procedures, and the specific controls in place, even the most sophisticated security measures can be rendered ineffective. Training ensures that the personnel are equipped with the necessary knowledge to perform their duties securely, while awareness programs help in maintaining a security-conscious culture within the organization.

References = This answer is supported by the CCAK materials which highlight the importance of training and awareness in cloud security. The Cloud Controls Matrix (CCM) also emphasizes the need for security education and the role it plays in the successful implementation of security controls1234.

During the implementation phase of a cloud assurance program, the focus is on establishing the operational aspects that will ensure the ongoing security and compliance of the cloud environment. This includes developing the monitoring goals and requirements which are essential for setting up the assurance framework. It involves determining what needs to be monitored, how it should be monitored, and the metrics that will be used to measure compliance and performance.

References = The information aligns with best practices for cloud migration and assurance programs as outlined in various resources, including the Cloud Assurance Program Guide by Microsoft Cybersecurity1, which discusses the importance of developing and implementing policies for cloud data and system migration, and the Enterprise Guide to Successful Cloud Adoption by New Relic2, which emphasizes the role of observability in cloud migration, including the establishment of monitoring goals.

It is most important for an auditor to be aware that an inventory of assets within a cloud environment is fundamental for the security management program. An inventory of assets is a list of all the hardware, software, data, and services that are owned, used, or managed by an organization in the cloud. An inventory of assets helps the organization to identify, classify, and prioritize its cloud resources and to implement appropriate security controls and policies to protect them. An inventory of assets also helps the organization to comply with relevant regulations, standards, and contracts that may apply to its cloud environment.12

An auditor should be aware of the importance of an inventory of assets in the cloud because it provides a baseline for assessing the security posture and compliance status of the organization’s cloud environment. An auditor can use the inventory of assets to verify that the organization has a clear and accurate understanding of its cloud resources and their characteristics, such as location, ownership, configuration, dependencies, vulnerabilities, and risks. An auditor can also use the inventory of assets to evaluate whether the organization has implemented adequate security measures and processes to protect its cloud resources from threats and incidents. An auditor can also use the inventory of assets to identify any gaps or weaknesses in the organization’s security management program and to provide recommendations for improvement.34

External attestation and certification audit reports are considered the best method to demonstrate assurance in cloud services to multiple customers because they provide an independent verification of the cloud service provider’s controls and practices. These reports are conducted by third-party auditors and offer a level of transparency and trust that cannot be achieved through self-assessments or internal documents. They help ensure that the cloud provider meets industry standards and regulatory requirements, which is crucial for customers to assess the risk and compliance posture of their cloud service providers.

References = The importance of external attestation and certification audit reports is supported by the Cloud Security Alliance (CSA) and ISACA, which state that the CCAK credential prepares IT and security professionals to ensure that the right controls are in place and to mitigate the risks and costs of audit management and penalties for non-compliance1.

The optimal and most efficient mechanism to assess the controls that the provider is responsible for is to review third-party audit reports. Third-party audit reports are independent and objective assessments of the provider’s security, compliance, and performance, conducted by qualified and reputable auditors. Third-party audit reports can provide assurance and evidence that the provider meets the industry standards and best practices, as well as the contractual and legal obligations with the SaaS company. Third-party audit reports can also cover a wide range of controls, such as data security, encryption, identity and access management, incident response, disaster recovery, and service level agreements. Some examples of third-party audit reports are ISO 27001 certification, SOC 1/2/3 reports, CSA STAR certification, and FedRAMP authorization123.

Reviewing the provider’s published questionnaires (A) may not be optimal or efficient, as the published questionnaires may not be comprehensive or up-to-date, and may not reflect the actual state of the provider’s controls. The published questionnaires may also be biased or inaccurate, as they are produced by the provider themselves.

Directly auditing the provider © may not be feasible or necessary, as the independent contractor may not have access to the provider’s environment or data, and may not have the authority or expertise to conduct such an audit. The independent contractor should rely on the third-party audit reports and certifications to assess the provider’s compliance with relevant standards and regulations.

Sending a supplier questionnaire to the provider (D) may not be optimal or efficient, as the supplier questionnaire may not cover all the aspects of the provider’s controls, and may not provide sufficient evidence or assurance of the provider’s security maturity. The supplier questionnaire may also take a long time to complete and verify, and may not be consistent with the industry standards and best practices. References :=

 The effect of applicable statutory requirements should have priority in planning the scope and objectives of a cloud audit, as they are the mandatory and enforceable rules that govern the cloud service provider and the cloud service customer. Statutory requirements may vary depending on the jurisdiction, industry, or sector of the cloud service provider and the cloud service customer, as well as the type, location, and sensitivity of the data processed or stored in the cloud. Statutory requirements may include laws, regulations, standards, or codes that relate to data protection, privacy, security, compliance, governance, taxation, or liability. The cloud auditor should identify and understand the applicable statutory requirements that affect the cloud service provider and the cloud service customer, and assess whether they are met and adhered to by both parties. The cloud auditor should also verify that the contractual terms and conditions between the cloud service provider and the cloud service customer reflect and comply with the applicable statutory requirements123.

Applicable industry good practices (A) are important for planning the scope and objectives of a cloud audit, but they are not as high priority as applicable statutory requirements. Industry good practices are the recommended or accepted methods or techniques for achieving a desired outcome or result in a specific domain or context. Industry good practices may include frameworks, guidelines, principles, or best practices that are developed by professional bodies, associations, or organizations that have expertise or authority in a certain field or area. Industry good practices may help the cloud service provider and the cloud service customer to improve their performance, quality, efficiency, or effectiveness in delivering or using cloud services. However, industry good practices are not mandatory or enforceable, and they may vary or change over time depending on the evolution of technology or business needs123.

Organizational policies and procedures © are important for planning the scope and objectives of a cloud audit, but they are not as high priority as applicable statutory requirements. Organizational policies and procedures are the internal rules and guidelines that define the objectives, expectations, and responsibilities of an organization regarding its operations, activities, processes, or functions. Organizational policies and procedures may include mission statements, vision statements, values statements, strategies, goals, plans, standards, manuals, handbooks, or instructions that are specific to an organization. Organizational policies and procedures may help the organization to align its actions and decisions with its purpose and direction, as well as to ensure consistency and accountability among its members or stakeholders. However, organizational policies and procedures are not mandatory or enforceable outside the organization, and they may differ or conflict among different organizations123.

Applicable corporate standards (D) are important for planning the scope and objectives of a cloud audit, but they are not as high priority as applicable statutory requirements. Corporate standards are the internal rules and guidelines that define the minimum level of quality, performance, reliability, or compatibility that an organization expects from its products, services, processes, or systems. Corporate standards may include specifications, criteria, metrics, indicators, benchmarks, or baselines that are specific to an organization. Corporate standards may help the organization to measure and evaluate its outputs or outcomes against its objectives or expectations, as well as to identify and address any gaps or issues that may arise. However, corporate standards are not mandatory or enforceable outside the organization, and they may differ or conflict among different organizations123. References :=

 In a multi-level supply chain structure, the cloud service provider should ensure that any compliance requirements relevant to the provider are passed to the sub cloud service providers, regardless of their geographic location. This is because the sub cloud service providers may have access to or process the data of the provider’s customers, and thus may affect the compliance status of the provider. The provider should also monitor and verify the compliance of the sub cloud service providers on a regular basis. This is part of the Cloud Control Matrix (CCM) domain COM-01: Regulatory Frameworks, which states that "The organization should identify and comply with applicable regulatory frameworks, contractual obligations, and industry standards."1 References := CCAK Study Guide, Chapter 3: Cloud Compliance Program, page 51

Regarding suppliers of a cloud service provider, it is most important for the auditor to be aware that the client organization has a clear understanding of the provider’s suppliers. This is because cloud services often involve multiple parties in the supply chain, such as cloud providers, sub-providers, brokers, carriers, and auditors. Each party may have different roles and responsibilities in delivering the cloud services and ensuring their quality, security, and compliance. Therefore, it is essential for the client organization to have visibility and assurance of the performance and compliance of the provider’s suppliers and to establish clear and transparent agreements with them regarding their roles, responsibilities, expectations, and obligations.12

An auditor should be aware of the importance of the client organization’s understanding of the provider’s suppliers because it provides a basis for assessing the risks and challenges associated with outsourcing services to a cloud provider and its supply chain. An auditor can use the client organization’s understanding of the provider’s suppliers to verify that the client organization has conducted a thorough due diligence of the provider’s suppliers and their capabilities, qualifications, certifications, and reputation. An auditor can also use the client organization’s understanding of the provider’s suppliers to evaluate whether the client organization has implemented adequate controls and processes to monitor, audit, or verify the security and compliance status of their cloud services and data across the supply chain. An auditor can also use the client organization’s understanding of the provider’s suppliers to identify any gaps or weaknesses in the client organization’s security management program and to provide recommendations for improvement.34

A cloud service provider (CSP) providing cloud services currently being used by the United States federal government should obtain FedRAMP Authorization to assure compliance to stringent government standards. FedRAMP is a government-wide program that provides a standardized approach to security assessment, authorization, and continuous monitoring for cloud products and services. FedRAMP enables agencies to leverage the security assessments of CSPs that have been approved by FedRAMP, and establishes a baseline set of security controls for cloud computing, based on NIST SP 800-53. FedRAMP also helps CSPs to demonstrate their compliance with relevant laws and regulations, such as FISMA, FIPS, and NIST standards. FedRAMP Authorization can be obtained through two paths: a provisional authorization from the Joint Authorization Board (JAB) or an authorization from an individual agency12.

The other options are incorrect because:

A. CSA STAR Level Certificate: CSA STAR is a program for security assurance in the cloud that encompasses key principles of transparency, rigorous auditing, and harmonization of standards. CSA STAR Level Certificate is one of the certification options offered by CSA STAR, which is based on the ISO/IEC 27001 standard and the CSA Cloud Controls Matrix (CCM). CSA STAR Level Certificate is not specific to the US federal government standards, and does not guarantee compliance with FedRAMP requirements3.

B. Multi-Tier Cloud Security (MTCS) Attestation: MTCS is a cloud security standard developed by the Singapore government to provide greater clarity and transparency on the level of security offered by different CSPs. MTCS defines three levels of security controls for CSPs: Level 1, Level 2, and Level 3, with Level 3 being the most stringent. MTCS Attestation is a voluntary self-disclosure scheme for CSPs to declare their conformance to the MTCS standard. MTCS Attestation is not applicable to the US federal government standards, and does not ensure compliance with FedRAMP requirements4.

C. ISO/IEC 27001:2013 Certification: ISO/IEC 27001 is a standard for information security management systems that specifies the requirements for establishing, implementing, maintaining, and continually improving an information security management system within the context of the organization. ISO/IEC 27001 Certification is an independent verification that an organization conforms to the ISO/IEC 27001 standard. ISO/IEC 27001 Certification is not exclusive to cloud computing or the US federal government standards, and does not cover all aspects of FedRAMP requirements5.

Customer management interfaces are the web portals or applications that allow customers to access and manage their cloud services, such as provisioning, monitoring, billing, etc. These interfaces are exposed to the public Internet and may be vulnerable to attacks such as phishing, malware, denial-of-service, or credential theft. If an attacker compromises a customer management interface, they can potentially access and manipulate the customer’s cloud resources, data, and configurations, leading to computing and data compromise for customers. This can result in data breaches, service disruptions, unauthorized transactions, or other malicious activities.

Reputational business impact refers to the effect on a company’s reputation and public perception following an incident or action. Option A is an example of reputational impact because the public dispute among high-level executives after a breach was reported reflects poorly on the company’s governance and crisis management capabilities. This public display of discord can erode stakeholder trust and confidence, potentially leading to a decline in the company’s market value, customer base, and ability to attract and retain talent.

References = The answer is derived from the understanding of reputational risk and its consequences on businesses, as discussed in various cloud auditing and security resources. Reputational impact is a key consideration in the governance of cloud operations, which is a topic covered in the CCAK curriculum1234.

A distributed denial of service (DDoS) attack renders the customer’s cloud inaccessible for 24 hours is an example of availability technical impact. Availability is the protection of data and services from disruption or denial, and it is one of the three dimensions of information security, along with confidentiality and integrity. Availability technical impact refers to the extent of damage or harm that a threat can cause to the availability of the information system and its components, such as servers, networks, applications, and data. A DDoS attack is a malicious attempt to overwhelm a target system with a large volume of traffic or requests from multiple sources, making it unable to respond to legitimate requests or perform its normal functions. A DDoS attack can cause a significant availability technical impact by rendering the customer’s cloud inaccessible for a prolonged period of time, resulting in loss of productivity, revenue, customer satisfaction, and reputation. References := CCAK Study Guide, Chapter 4: A Threat Analysis Methodology for Cloud Using CCM, page 81; What is a DDoS Attack? | Cloudflare

The Egregious 11 refers to a list of top threats to cloud computing, as published by the Cloud Security Alliance (CSA) in 2019. The CSA is a leading organization dedicated to defining standards, certifications and best practices to help ensure a secure cloud computing environment. The Egregious 11 report ranks the most critical and pressing cloud security issues, such as data breaches, misconfigurations, insufficient identity and access management, and account hijacking. The report also provides recommendations for security, compliance, risk and technology practitioners to mitigate these threats. The Egregious 11 is based on a survey of industry experts and a review of current literature and media reports. The report is intended to raise awareness of the risks and challenges associated with cloud computing and promote strong security practices.12 References := CCAK Study Guide, Chapter 5: Cloud Auditing, page 961; CSA Top Threats to Cloud Computing: Egregious 11

 Under the General Data Protection Regulation (GDPR), organizations are required to report a data breach to the appropriate supervisory authority within 72 hours of becoming aware of it. This timeframe is critical to ensure timely communication with the authorities and affected individuals, if necessary, to mitigate any potential harm caused by the breach.

References = This requirement is outlined in the GDPR guidelines, which emphasize the importance of prompt reporting to maintain compliance and protect individual rights and freedoms12345.

Transparent data encryption (TDE) is used for data and log files at rest. This means that TDE encrypts the database files on the disk and decrypts them when they are read into memory. TDE protects the data from unauthorized access or theft if the physical media, such as drives or backup tapes, are stolen or lost. TDE does not encrypt data across communication channels, data currently being processed, or data in random access memory (RAM). These types of data require different encryption methods, such as SSL/TLS, column encryption, or memory encryption12.

The first step to switch from the ISO/IEC 27002 control framework to the NIST 800-53 control framework is to map ISO/IEC 27002 and NIST 800-53 and detect gaps and commonalities. This step can help the organization to understand the similarities and differences between the two frameworks, and to identify which controls are already implemented, which controls need to be added or modified, and which controls are no longer applicable. Mapping can also help the organization to leverage the existing work done under ISO/IEC 27002 and avoid starting from scratch or discarding valuable information. Mapping can also help the organization to align with both frameworks, as they are not mutually exclusive or incompatible. In fact, NIST SP 800-53, Revision 5 provides a mapping table between NIST 800-53 and ISO/IEC 27001 in Appendix H-21. ISO/IEC 27001 is a standard for information security management systems that is based on ISO/IEC 27002, which is a code of practice for information security controls2.

According to the definition of audit scope, it is the extent and boundaries of an audit, which include the audit objectives, the activities and documents covered, the time period and locations audited, and the related activities not audited1 Audit scope determines how deeply an audit is performed and may vary depending on the type of audit. Audit scope can also mean the examination of a person or the inspection of the books, records, or accounts of a person for tax purposes1

The most important audit scope document when conducting a review of a cloud service provider is the processes and systems to be audited. This document defines the specific areas and aspects of the cloud service provider that will be subject to the audit, such as the cloud service delivery model, the cloud deployment model, the cloud security domains, the cloud service level agreements, the cloud governance framework, etc2 The processes and systems to be audited document also helps to identify the risks, controls, criteria, and objectives of the audit, as well as the roles and responsibilities of the auditors and the auditees3 The processes and systems to be audited document is essential for planning and performing an effective and efficient audit of a cloud service provider.

The other options are not correct because:

Option B is not correct because the updated audit work program is not an audit scope document, but rather an audit planning document. The audit work program is a set of detailed instructions or procedures that guide the auditor in conducting the audit activities4 The audit work program is based on the audit scope, but it does not define it. The audit work program may also change during the course of the audit, depending on the findings and issues encountered by the auditor4

Option C is not correct because the documentation criteria for the audit evidence is not an audit scope document, but rather an audit quality document. The documentation criteria for the audit evidence is a set of standards or guidelines that specify what constitutes sufficient and appropriate evidence to support the auditor’s conclusions and opinions5 The documentation criteria for the audit evidence is derived from the audit scope, but it does not determine it. The documentation criteria for the audit evidence may also vary depending on the nature and source of the evidence collected by the auditor5

Option D is not correct because the testing procedure to be performed is not an audit scope document, but rather an audit execution document. The testing procedure to be performed is a set of steps or actions that describe how to test or verify a specific control or process within the cloud service provider6 The testing procedure to be performed is aligned with the audit scope, but it does not establish it. The testing procedure to be performed may also differ depending on the type and level of testing required by the auditor6

 An auditor examining a cloud service provider’s SLA should be most concerned about whether the agreement excludes any operational matters that are material to the service operations, as this could indicate a lack of transparency, accountability, and quality assurance from the provider. Operational matters are the aspects of the cloud service that affect its functionality, performance, availability, reliability, security, and compliance. Examples of operational matters include service scope, roles and responsibilities, service levels and metrics, monitoring and reporting mechanisms, incident and problem management, change management, backup and recovery, data protection and privacy, and termination and exit clauses12. These matters are material to the service operations if they have a significant impact on the achievement of the service objectives and expectations of the cloud customer. The auditor should verify that the SLA covers all the relevant and material operational matters in a clear and comprehensive manner, and that the provider adheres to the SLA terms and conditions.

The other options are not the most concerning for the auditor. Option A is a desirable feature of an SLA, but not a concern if it is missing. Option B is an unrealistic expectation of an SLA, as sourcing and financial matters are usually essential in meeting the SLA. Option C is a specific example of an operational matter that is material to the service operations, but not the only one that should be included in the SLA. References:

Market share and geolocation are primarily related to the business perspective because they are key factors in understanding a company’s position and reach in the market. Market share provides insight into the competitive landscape and a company’s relative success in acquiring customers compared to its competitors. Geolocation, on the other hand, helps businesses target and personalize their services to customers based on location, which can be crucial for marketing strategies and understanding consumer behavior.

References = The relevance of market share and geolocation to the business perspective is highlighted in resources provided by ISACA and the Cloud Security Alliance (CSA). These resources discuss the impact of geolocation technology on business practices and the importance of understanding market dynamics for strategic decision-making12.

The most important audit scope document when conducting a review of a cloud service provider is the document that defines the processes and systems to be audited. This document should clearly identify the objectives, criteria, and boundaries of the audit, as well as the roles and responsibilities of the audit team and the cloud service provider. The document should also specify the scope of the cloud service provider’s services, such as the service model, deployment model, geographic location, data classification, and compliance requirements. The document should also describe the scope of the audit evidence, such as the types, sources, methods, and sampling techniques of data collection and analysis. The document should also state the expected deliverables, timelines, and reporting formats of the audit. The document should be agreed upon by both parties before the audit commences.

The document that defines the processes and systems to be audited is essential for ensuring that the audit is relevant, reliable, consistent, and complete. It helps to establish a common understanding and expectation between the auditor and the auditee, as well as to avoid any misunderstandings or conflicts during or after the audit. It also helps to focus the audit on the key risks and controls related to the cloud service provider’s operations and performance. It also helps to ensure that the audit complies with the applicable standards, frameworks, and regulations.

The auditor’s next course of action should be to review the contract and DR capability of the cloud service provider. The contract should specify the roles and responsibilities of both parties regarding disaster recovery, as well as the service level agreements (SLAs) and recovery time objectives (RTOs) for the critical application. The DR capability should demonstrate that the cloud service provider has a plan that is aligned with the organization’s requirements and expectations, and that it is tested annually and validated by independent auditors. The auditor should also verify that the organization has a process to monitor and review the cloud service provider’s performance and compliance with the contract and SLAs.

Planning an audit of the provider (B) may not be feasible or necessary, as the auditor may not have access to the provider’s environment or data, and may not have the authority or expertise to conduct such an audit. The auditor should rely on the provider’s audit reports and certifications to assess their compliance with relevant standards and regulations.

Reviewing the security white paper of the provider © may not be sufficient or relevant, as the security white paper may not cover the specific aspects of disaster recovery for the critical application, or may not reflect the current state of the provider’s security controls and practices. The security white paper may also be biased or outdated, as it is produced by the provider themselves.

Reviewing the provider’s audit reports (D) may be helpful, but not enough, as the audit reports may not address the specific requirements and expectations of the organization for disaster recovery, or may not cover the latest changes or incidents that may affect the provider’s DR capability. The audit reports may also have limitations or qualifications that may affect their reliability or validity. References :=

How to Maintain and Test a Business Continuity and Disaster Recovery Plan

Establishing ownership and accountability most enhances the internal stakeholder decision-making process for the remediation of risks identified from an organization’s cloud compliance program. Cloud compliance refers to the principle that cloud-delivered systems must comply with the standards required by their customers. Compliance requirements may include data protection regulations such as HIPAA, PCI DSS, GDPR, ISO/IEC 27001, NIST, and SOX. A cloud compliance program is a set of policies, procedures, and controls that help an organization to achieve and maintain compliance with these requirements12.

A cloud compliance program involves identifying, assessing, prioritizing, and mitigating the risks associated with using cloud services. To effectively manage these risks, an organization needs to establish ownership and accountability for each risk and its remediation. Ownership and accountability mean assigning clear roles and responsibilities to the internal stakeholders who are involved in the cloud compliance program, such as the cloud service provider, the cloud customer, the cloud users, the cloud auditors, and the cloud regulators. By doing so, an organization can ensure that the internal stakeholders have the authority, resources, and incentives to make timely and informed decisions for the remediation of risks123.

The other options are not the most effective ways to enhance the internal stakeholder decision-making process for the remediation of risks. Option A, automating risk monitoring and reporting processes, is a good practice for improving the efficiency and accuracy of the cloud compliance program, but it does not address the issue of who is responsible for making decisions based on the monitoring and reporting results. Option B, reporting emerging threats to senior stakeholders, is a good practice for increasing the awareness and visibility of the cloud compliance program, but it does not address the issue of how to prioritize and respond to the emerging threats. Option D, monitoring key risk indicators (KRIs) for multi-cloud environments, is a good practice for measuring and tracking the performance and effectiveness of the cloud compliance program, but it does not address the issue of how to align and coordinate the decisions across different cloud environments123. References :=

According to the ISACA Cloud Auditing Knowledge Certificate Study Guide, the primary goal of a cloud auditor during the planning phase of a cloud audit is to address audit objectives1. The audit objectives are the specific questions that the audit aims to answer, such as whether the cloud service meets the security, compliance, performance, and availability requirements of the cloud customer. The audit objectives should be aligned with the organization’s context, risk appetite, and expectations. The audit objectives should also be clear, measurable, achievable, relevant, and timely.

The other options are not the primary goal of a cloud auditor during the planning phase of a cloud audit. Option A is a possible activity, but not the main goal of the planning phase. The appropriate tests are determined based on the audit objectives, criteria, and methodology. Option C is a possible constraint, but not the main goal of the planning phase. The audit resources should be allocated based on the audit scope, complexity, and significance. Option D is a possible outcome, but not the main goal of the planning phase. The sufficient evidence is collected during the execution phase of the audit, based on the audit plan. References:

Rotating cryptographic keys regularly is a security best practice that helps to mitigate the risk of unauthorized access to encrypted data. When keys are rotated, old keys are retired and replaced with new ones, making any compromised keys useless to an attacker. This process helps to limit the time window during which a stolen key can be used to breach data. Key rotation is a fundamental aspect of key management lifecycle best practices, which include generating new key pairs, rotating keys at set intervals, revoking access to keys, and destroying out-of-date or compromised keys.

References = The importance of key rotation is supported by various security standards and best practices, including recommendations from the National Institute of Standards and Technology (NIST)1 and the Cloud Security Alliance (CSA)23. These sources emphasize the need for periodic renewal and decommissioning of old keys as part of a comprehensive key management strategy.

Visibility to the source code within build scripts would give an auditor the best view of design and implementation decisions when an organization uses programmatic automation for Infrastructure as a Service (IaaS) deployments. IaaS is a cloud service model that provides virtualized computing resources, such as servers, storage, network, and operating systems, over the internet. Programmatic automation is the process of using code or scripts to automate the provisioning, configuration, management, and monitoring of the cloud infrastructure. Build scripts are files that contain commands or instructions to create or modify the cloud infrastructure according to the desired specifications.12

An auditor can use the source code within build scripts to gain insight into how the organization designs and implements its cloud infrastructure. The source code can reveal the following information3:

The type, size, and number of cloud resources that are provisioned and deployed

The configuration settings and parameters that are applied to the cloud resources

The security controls and policies that are enforced on the cloud resources

The dependencies and relationships between the cloud resources

The testing and validation methods that are used to verify the functionality and performance of the cloud resources

The logging and auditing mechanisms that are used to track and record the changes and activities on the cloud resources

By reviewing the source code within build scripts, an auditor can evaluate whether the organization follows the best practices and standards for cloud infrastructure design and implementation, such as scalability, reliability, security, compliance, and efficiency. An auditor can also identify any gaps or risks in the organization’s cloud infrastructure and provide recommendations for improvement.

 According to the ISACA Cloud Auditing Knowledge Certificate Study Guide, the primary objective for an auditor to understand the organization’s context for a cloud audit is to validate an understanding of the organization’s current state and how the cloud audit plan fits into the existing audit approach1. The auditor should consider the organization’s business objectives, strategies, risks, and opportunities, as well as the regulatory and contractual requirements that apply to the organization’s use of cloud services. The auditor should also assess the organization’s cloud maturity level, governance structure, policies and procedures, roles and responsibilities, and existing controls related to cloud services. The auditor should then align the cloud audit plan with the organization’s context and ensure that it covers the relevant scope, objectives, criteria, and methodology.

The other options are not the primary objective for an auditor to understand the organization’s context for a cloud audit. Option A is a possible audit procedure, but not the main goal of understanding the organization’s context. Option C is a possible audit outcome, but not the main purpose of understanding the organization’s context. Option D is a possible audit finding, but not the main reason for understanding the organization’s context. References:

ISO/IEC 27017:2015 is a standard that provides guidelines for information security controls applicable to the provision and use of cloud services by providing additional implementation guidance for relevant controls specified in ISO/IEC 27002, as well as additional controls with implementation guidance that specifically relate to cloud services1. ISO/IEC 27017:2015 is designed to be used by organizations for cloud services that intend to select controls within the process of implementing an information security management system based on ISO/IEC 27001, which is the international standard for information security management systems1. ISO/IEC 27017:2015 can help organizations to establish, implement, maintain and continually improve their information security in the cloud environment, as well as to demonstrate compliance with contractual and legal obligations1.

ISO/IEC 27002 is a code of practice for information security controls that provides best practice recommendations on information security management for use by those who are responsible for initiating, implementing or maintaining information security management systems2. However, ISO/IEC 27002 does not provide specific guidance for cloud services, which is why ISO/IEC 27017:2015 was developed as an extension to ISO/IEC 27002 for cloud services1.

Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) is a set of security controls that provides organizations with a detailed understanding of security concepts and principles that are aligned to the cloud model. The CCM is not a standard, but rather a framework that can be used to assess the overall security risk of a cloud provider. The CCM can also be mapped to other standards, such as ISO/IEC 27001 and ISO/IEC 27017:2015, to facilitate compliance and assurance activities.

NIST SP 800-146 is a publication from the National Institute of Standards and Technology (NIST) that provides an overview of cloud computing, its characteristics, service models, deployment models, benefits, challenges and considerations. NIST SP 800-146 is not a standard, but rather a reference document that can help organizations to understand the basics of cloud computing and its implications for information security. NIST SP 800-146 does not provide specific guidance or controls for cloud services, but rather refers to other standards and frameworks, such as ISO/IEC 27001 and CSA CCM, for more detailed information on cloud security. References :=

A SOC2 Type 2 report can best help an auditor to get information about the operating effectiveness of controls addressing privacy, availability, and confidentiality of a service organization. A SOC2 Type 2 report is an internal control report that examines the security, availability, processing integrity, confidentiality, and privacy of a service organization’s system and data over a specified period of time, typically 3-12 months. A SOC2 Type 2 report is based on the AICPA Trust Services Criteria and provides an independent auditor’s opinion on the design and operating effectiveness of the service organization’s controls. A SOC2 Type 2 report can help an auditor to assess the risks and challenges associated with outsourcing services to a cloud provider and to verify that the provider meets the relevant compliance requirements and industry standards.12 References := CCAK Study Guide, Chapter 5: Cloud Auditing, page 971; SOC 2 Type II Compliance: Definition, Requirements, and Why You Need It2

Risk appetite and budget constraints have the most substantial impact on how aggressive or conservative the cloud approach of an organization will be. Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Budget constraints are the limitations on the financial resources that an organization can allocate to its cloud initiatives. Both factors influence the organization’s strategic decisions on which cloud service models, deployment models, providers, and solutions to adopt, as well as the level of security, compliance, and performance to achieve. An organization with a high risk appetite and a large budget may opt for a more aggressive cloud approach, such as moving critical applications and data to a public cloud provider, while an organization with a low risk appetite and a small budget may opt for a more conservative cloud approach, such as keeping sensitive information on-premises or using a private cloud provider12.

A centralized risk and controls dashboard is the best option for ensuring a coordinated approach to risk and control processes when duties are split between an organization and its cloud service providers. This dashboard provides a unified view of risk and control status across the organization and the cloud services it utilizes. It enables both parties to monitor and manage risks effectively and ensures that control activities are aligned and consistent. This approach supports proactive risk management and facilitates communication and collaboration between the organization and the cloud service provider.

References = The concept of a centralized risk and controls dashboard is supported by the Cloud Security Alliance (CSA) and ISACA, which emphasize the importance of visibility and coordination in cloud risk management. The CCAK materials and the Cloud Controls Matrix (CCM) provide guidance on establishing such dashboards as a means to manage and mitigate risks in a cloud environment12.

The technical impact of this incident would be categorized as an integrity breach in reference to the Top Threats Analysis methodology. The Top Threats Analysis methodology is a process developed by the Cloud Security Alliance (CSA) to help organizations identify, analyze, and mitigate the top threats to cloud computing, as defined in the CSA Top Threats reports. The methodology consists of six steps: scope definition, threat identification, technical impact identification, business impact identification, risk assessment, and risk treatment. Each of these provides different insights and visibility into the organization’s security posture.1

The technical impact identification step involves determining the impact on confidentiality, integrity, and availability of the information system caused by each threat. Confidentiality refers to the protection of data from unauthorized access or disclosure. Integrity refers to the protection of data from unauthorized modification or deletion. Availability refers to the protection of data and services from disruption or denial.2

An integrity breach occurs when a threat compromises the accuracy and consistency of the data or system. An integrity breach can result in data corruption, falsification, or manipulation, which can affect the reliability and trustworthiness of the data or system. An integrity breach can also have serious consequences for the business operations and decisions that depend on the data or system.3

In this case, the cybersecurity criminal was able to access an encrypted file system and overwrite parts of some files with random data. This means that the data in those files was altered without authorization and became unusable or invalid. This is a clear example of an integrity breach, as it violated the principle of ensuring that data is accurate and consistent throughout its lifecycle.4

In the context of cloud operationalization, “below the waterline” refers to the aspects of cloud services that are managed and controlled by the cloud service provider (CSP) rather than the customer. This analogy is often used to describe the shared responsibility model in cloud computing, where the CSP is responsible for the infrastructure’s security and stability, akin to the submerged part of an iceberg that supports the structure above water. The customer, on the other hand, is responsible for managing the controls and security measures “above the waterline,” which include the applications, data, and access management they deploy in the cloud environment.

References = The information provided is based on standard cloud computing models and the shared responsibility concept, which is a fundamental principle discussed in cloud auditing and security literature, including the CCAK curriculum and related resources1.

 The three layers of the Open Certification Framework (OCF) primarily help cloud service providers and cloud clients improve the level of transparency and assurance. The OCF is designed to provide a trusted and independent evaluation of cloud providers through a flexible, incremental, and multi-layered certification process. This framework enhances transparency by making it easier for consumers to understand and compare providers’ security and compliance capabilities. Additionally, it offers assurance by integrating with third-party assessment and attestation statements, thereby increasing the security baseline for all participants.

References = The benefits of the OCF in improving transparency and assurance are detailed in the Cloud Security Alliance’s documentation on the Open Certification Framework1.

DevSecOps is an approach that integrates security practices into every phase of the software development lifecycle. It emphasizes the incorporation of security from the beginning, rather than as an afterthought, and utilizes automation to ensure security measures are consistently applied throughout the development process. This method allows for early detection and resolution of security issues, making it an essential practice for organizations with mature security programs and cloud adoption.

References = The definition and best practices of DevSecOps are well-documented in resources provided by leading industry authorities such as Microsoft1 and IBM2, which describe DevSecOps as a framework that automates the integration of security into the software development lifecycle.

The Cloud Octagon Model was developed to support organizations’ risk assessment methodology. Risk assessment is the process of identifying, analyzing, and evaluating the risks associated with a cloud computing environment. The Cloud Octagon Model provides a logical approach to holistically deal with security aspects involved in moving to the cloud by introducing eight dimensions that need to be considered: procurement, IT governance, architecture, development and engineering, service providers, risk processes, data classification, and country. The model aims to reduce risks, improve effectiveness, manageability, and security of cloud solutions12.

Periodic documentation review is a critical process that helps organizations identify control gaps and shortcomings, particularly in the context of cloud computing. This process involves regularly examining the documentation of processes, controls, and policies to ensure they are up-to-date and effective. It allows an organization to verify that the controls are operating as intended and to discover any areas where the controls may not fully address the organization’s requirements or the unique risks associated with cloud services. By conducting these reviews, organizations can maintain compliance with relevant regulations and standards, and ensure continuous improvement in their cloud security posture.

References = The significance of periodic documentation review is highlighted in cloud auditing and security best practices, as outlined by the Cloud Security Alliance (CSA) and the Certificate of Cloud Auditing Knowledge (CCAK) program12. These resources emphasize the importance of regular reviews as part of a comprehensive cloud governance and compliance strategy.

 In the context of Infrastructure as a Service (IaaS), a vulnerability assessment will scan virtual machines to identify vulnerabilities in both operating system and application infrastructure contained within the customer’s instances. IaaS is a cloud service model that provides customers with access to virtualized computing resources, such as servers, storage, and networks, hosted by a cloud service provider (CSP). The customer is responsible for installing, configuring, and maintaining the operating system and application software on the virtual machines, while the CSP is responsible for managing the underlying physical infrastructure. Therefore, a vulnerability assessment will scan the customer’s instances to detect any weaknesses or misconfigurations in the operating system and application layers that may expose them to potential threats. A vulnerability assessment can help the customer to prioritize and remediate the identified vulnerabilities, and to comply with relevant security standards and regulations12.

 Contracts and SLAs are legal documents that define the roles, responsibilities, expectations, and obligations of both the cloud service provider (CSP) and the cloud customer. They also specify the terms and conditions for service delivery, performance, availability, security, compliance, data protection, incident response, dispute resolution, liability, and termination. An auditor should review these documents to assess the alignment of the CSP’s services with the customer’s business requirements and risk appetite, as well as to identify any gaps or inconsistencies that may pose legal risks. References:

Identity and access management (IAM) and data protection are the areas that should be reviewed when auditing a public cloud, as they are the key aspects of cloud security and compliance that affect both the cloud service provider and the cloud service customer. IAM and data protection refer to the methods and techniques that ensure the confidentiality, integrity, and availability of data and resources in the cloud environment. IAM involves the use of credentials, policies, roles, permissions, and tokens to verify the identity and access rights of users or devices. Data protection involves the use of encryption, backup, recovery, deletion, and retention to protect data from unauthorized access, modification, loss, or disclosure123.

Patching and configuration (A) are not the areas that should be reviewed when auditing a public cloud, as they are not the key aspects of cloud security and compliance that affect both the cloud service provider and the cloud service customer. Patching and configuration refer to the processes and practices that ensure the security, reliability, and performance of the cloud infrastructure, platform, or software. Patching involves the use of updates or fixes to address vulnerabilities, bugs, errors, or exploits that may compromise or affect the functionality of the cloud components. Configuration involves the use of settings or parameters to customize or optimize the functionality of the cloud components. Patching and configuration are mainly under the responsibility of the cloud service provider, as they own and operate the cloud infrastructure, platform, or software. The cloud service customer has limited or no access or control over these aspects123.

Vulnerability management and cyber security reviews (B) are not the areas that should be reviewed when auditing a public cloud, as they are not specific or measurable aspects of cloud security and compliance that can be easily audited or tested. Vulnerability management and cyber security reviews refer to the processes and practices that identify, assess, treat, monitor, and report on the risks that affect the security posture of an organization or a domain. Vulnerability management involves the use of tools or techniques to scan, analyze, prioritize, remediate, or mitigate vulnerabilities that may expose an organization or a domain to threats or attacks. Cyber security reviews involve the use of tools or techniques to evaluate, measure, benchmark, or improve the security capabilities or maturity of an organization or a domain. Vulnerability management and cyber security reviews are general or broad terms that encompass various aspects of cloud security and compliance, such as IAM, data protection, patching, configuration, etc. Therefore, they are not specific or measurable areas that can be audited or tested individually123.

Source code reviews and hypervisor (D) are not the areas that should be reviewed when auditing a public cloud, as they are not relevant or accessible aspects of cloud security and compliance for most cloud service customers. Source code reviews refer to the processes and practices that examine the source code of software applications or systems to identify errors, bugs, vulnerabilities, or inefficiencies that may affect their quality, functionality, or security. Hypervisor refers to the software that allows the creation and management of virtual machines on a physical server. Source code reviews and hypervisor are mainly under the responsibility of the cloud service provider, as they own and operate the software applications or systems that deliver cloud services. The cloud service customer has no access or control over these aspects123. References :=

 The CSA STAR Attestation allows for the immediate adoption of the Cloud Controls Matrix (CCM) as additional criteria alongside the AICPA Trust Service Criteria. It also offers the flexibility to update the criteria as technology and market requirements evolve. This is because the CSA STAR Attestation is a combination of SOC 2 and additional cloud security criteria from the CSA CCM, providing guidelines for CPAs to conduct SOC 2 engagements using criteria from both the AICPA and the CSA Cloud Controls Matrix.

References = The information is supported by the Cloud Security Alliance’s resources, which explain that the CSA STAR Attestation integrates SOC 2 with additional criteria from the CCM, allowing for a comprehensive approach to cloud security that aligns with evolving technologies and market needs1.

One possible reason why the results of third-party audits and certification should be relied on when analyzing and assessing the cybersecurity risks in the cloud is to contrast the risk generated by the loss of control. When an organization moves its data and processes to the cloud, it inevitably loses some degree of control over its security and compliance posture, as it depends on the cloud service provider (CSP) to implement and maintain adequate security measures and controls1 This loss of control can increase the organization’s exposure to various cybersecurity risks, such as data breaches, unauthorized access, denial of service, malware infection, etc2

To mitigate these risks, the organization needs to have a clear understanding of the security and compliance level of the CSP, as well as the shared responsibility model that defines the roles and responsibilities of both parties3 Third-party audits and certification can provide some level of assurance that the CSP meets certain standards and requirements related to security and compliance, such as ISO/IEC 27001, CSA STAR, SOC 2, etc. These audits and certification can also help the organization compare and contrast the security posture of different CSPs in the market, as well as identify any gaps or weaknesses that need to be addressed or compensated.

Therefore, relying on the results of third-party audits and certification can help the organization contrast the risk generated by the loss of control in the cloud, and make informed decisions about selecting and managing its cloud services.

Regression testing is a type of software testing that confirms that a recent program or code change has not adversely affected existing features1 It involves re-running functional and non-functional tests to ensure that previously developed and tested software still performs as expected after a change2 Regression testing is suitable for large code sets in environments where time to completion is critical, as it can help detect and prevent defects, improve quality, and enable faster delivery of secure software. Regression testing can be automated to reduce manual errors, speed up feedback loops, and increase efficiency and reliability3

The other options are not correct because:

Option A is not correct because parallel testing is a type of software testing that involves testing multiple applications or subsystems concurrently to reduce the test time4 Parallel testing does not necessarily ensure the integration of security testing, as it depends on the quality and coverage of the test cases and scenarios used for each application or subsystem. Parallel testing may also introduce challenges such as synchronization, coordination, and communication among the testers and developers5

Option B is not correct because full application stack unit testing is a type of software testing that involves testing individual units or components of an application in isolation to verify their functionality, logic, interfaces, and performance6 Full application stack unit testing does not ensure the integration of security testing, as it does not consider the interactions and dependencies among the units or components, or the behavior of the application as a whole. Unit testing is typically performed by developers at an early stage of the software development life cycle, and may not cover all the security aspects or requirements of the application7

Option C is not correct because functional verification is a type of software testing that involves verifying that the software meets the specified requirements and satisfies the user needs. Functional verification does not ensure the integration of security testing, as it does not focus on how the software is designed or configured, or how it handles malicious or unexpected inputs. Functional verification is typically performed by quality assurance teams at a later stage of the software development life cycle, and may not detect all the security vulnerabilities or risks of the software.

According to the blog article “Continuous Auditing and Continuous Certification” by the Cloud Security Alliance, a certification target helps in the formation of a continuous certification framework by incorporating the scope description and security attributes to be tested1 A certification target is a set of security objectives that a cloud service provider (CSP) defines and commits to fulfill as part of the continuous certification process1 Each security objective is associated with a policy that specifies the assessment frequency, such as every four hours, every day, or every week1 A certification target also includes a set of tools that are capable of verifying that the security objectives are met, such as automated scripts, APIs, or third-party services1

The other options are not correct because:

Option A is not correct because the service level objective (SLO) and service qualitative objective (SQO) are not part of the certification target, but rather part of the service level agreement (SLA) between the CSP and the cloud customer. An SLO is a measurable characteristic of the cloud service, such as availability, performance, or reliability. An SQO is a qualitative characteristic of the cloud service, such as security, privacy, or compliance2 The SLA defines the expected level of service and the consequences of not meeting it. The SLA may be used as an input for defining the certification target, but it is not equivalent or synonymous with it.

Option C is not correct because the frequency of evaluating security attributes is not the only component of the certification target, but rather one aspect of it. The frequency of evaluating security attributes is determined by the policy that is associated with each security objective in the certification target. The policy defines how often the security objective should be verified by the tools, such as every four hours, every day, or every week1 However, the frequency alone does not define the certification target, as it also depends on the scope description and the security attributes to be tested.

Option D is not correct because CSA STAR level 2 attestation is not a component of the certification target, but rather a prerequisite for it. CSA STAR level 2 attestation is a third-party independent assessment of the CSP’s security posture based on ISO/IEC 27001 and CSA Cloud Controls Matrix (CCM)3 CSA STAR level 2 attestation provides a baseline assurance level for the CSP before they can define and implement their certification target for continuous certification. CSA STAR level 2 attestation is also required for CSA STAR level 3 certification, which is based on continuous auditing and continuous certification3

Cryptography and authentication are good candidates for continuous auditing, as they are critical aspects of cloud security that require constant monitoring and verification. Cryptography and authentication refer to the methods and techniques that ensure the confidentiality, integrity, and availability of data and communications in the cloud environment. Cryptography involves the use of encryption algorithms and keys to protect data from unauthorized access or modification. Authentication involves the use of credentials and tokens to verify the identity and access rights of users or devices. Continuous auditing can help to assess the effectiveness and compliance of cryptography and authentication controls, such as data encryption, key management, password policies, multifactor authentication, single sign-on, etc. Continuous auditing can also help to detect and alert any anomalies or issues that may compromise or affect cryptography and authentication, such as data breaches, key leakage, password cracking, unauthorized access, etc123.

Procedures (A) are not good candidates for continuous auditing, as they are not specific or measurable aspects of cloud security that can be easily automated or tested. Procedures refer to the steps or actions that are performed to achieve a certain objective or result in a specific domain or context. Procedures may vary depending on the type, nature, or complexity of the task or process involved. Continuous auditing requires a clear and consistent definition of the expected outcome or output, as well as the criteria or metrics to evaluate it. Procedures may not provide such a definition or criteria, and may require human judgment or interpretation to assess their effectiveness or compliance123.

Governance (B) is not a good candidate for continuous auditing, as it is not a specific or measurable aspect of cloud security that can be easily automated or tested. Governance refers to the framework or system that defines the roles, responsibilities, policies, standards, procedures, and practices for managing and overseeing an organization or a domain. Governance may involve multiple stakeholders, such as management, board of directors, regulators, auditors, customers, etc., who have different interests, expectations, or perspectives. Continuous auditing requires a clear and consistent definition of the expected outcome or output, as well as the criteria or metrics to evaluate it. Governance may not provide such a definition or criteria, and may require human judgment or interpretation to assess its effectiveness or compliance123.

Documentation quality (D) is not a good candidate for continuous auditing, as it is not a specific or measurable aspect of cloud security that can be easily automated or tested. Documentation quality refers to the degree to which the documents that describe or support an organization or a domain are accurate, complete, consistent, relevant, and understandable. Documentation quality may depend on various factors, such as the purpose, audience, format, style, language, structure, content, etc., of the documents involved. Continuous auditing requires a clear and consistent definition of the expected outcome or output, as well as the criteria or metrics to evaluate it. Documentation quality may not provide such a definition or criteria, and may require human judgment or interpretation to assess its effectiveness or compliance123. References :=

Cloud Auditing Knowledge: Preparing for the CCAK Certificate Exam

In multi-cloud environments, organizations use cloud services from multiple providers. This can lead to challenges in maintaining visibility and control over the data and services due to the varying management tools, processes, and security controls across different providers. The complexity of managing multiple service models and the reliance on different cloud service providers can reduce an organization’s ability to monitor and control its resources effectively, thus increasing the risk of reduced visibility and control.

References = The information aligns with the principles outlined in the CCAK materials, which emphasize the unique challenges of auditing the cloud, including ensuring the right controls for confidentiality, integrity, and accessibility, and mitigating risks such as those associated with multi-cloud environments12.

 ISO/IEC 15027017 is a cloud-specific security standard that provides guidelines for information security controls applicable to the provision and use of cloud services. It is based on ISO/IEC 27002, which is a general standard for information security management, but it also includes additional controls and implementation guidance that specifically relate to cloud services. ISO/IEC 15027017 is intended to help both cloud service providers and cloud service customers to enhance the security and confidentiality of their cloud environment and to comply with relevant regulatory requirements and industry standards.12 References := ISO/IEC 27017:2015 - Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services1; Cloud Security Standards: ISO, PCI, GDPR and Your Cloud - Exabeam3; ISO/IEC 27017 - Wikipedia2

 According to the cloud shared responsibility model, the cloud customer is responsible for managing the access controls for the SaaS functionality and operations, and this should be audited by the cloud auditor12. Access controls are the mechanisms that restrict and regulate who can access and use the SaaS applications and data, and how they can do so. Access controls include identity and access management, authentication, authorization, encryption, logging, and monitoring. The cloud customer is responsible for defining and enforcing the access policies, roles, and permissions for the SaaS users, as well as ensuring that the access controls are aligned with the security and compliance requirements of the customer’s business context12.

The other options are not the aspects of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Option B is incorrect, as vulnerability management is the process of identifying, assessing, and mitigating the security weaknesses in the SaaS applications and infrastructure, and this is usually handled by the cloud service provider12. Option C is incorrect, as patching is the process of updating and fixing the SaaS applications and infrastructure to address security issues or improve performance, and this is also usually handled by the cloud service provider12. Option D is incorrect, as source code reviews are the process of examining and testing the SaaS applications’ source code to detect errors or vulnerabilities, and this is also usually handled by the cloud service provider12. References:

 A dot release of the Cloud Controls Matrix (CCM) indicates a technical change (revision, addition, or deletion) of a number of controls that is smaller than 10% compared to the previous full release. A dot release is a minor update to the CCM that reflects the feedback from the cloud security community and the changes in the cloud technology landscape. A dot release does not change the domain structure or the overall scope of the CCM, but rather improves the clarity, accuracy, and relevance of the existing controls. A dot release is denoted by a decimal number after the major version number, such as CCM v4.1 or CCM v4.2. The current version of the CCM is v4.0, which was released in October 20211.

The other options are incorrect because:

A. a revision of the CCM domain structure: A revision of the CCM domain structure is a major change that affects the organization and categorization of the controls into different domains. A revision of the CCM domain structure requires a full release, not a dot release, and is denoted by an integer number, such as CCM v3 or CCM v42.

C. the introduction of new control frameworks mapped to previously published CCM controls: The introduction of new control frameworks mapped to previously published CCM controls is an additional feature that enhances the usability and applicability of the CCM. The introduction of new control frameworks mapped to previously published CCM controls does not require a dot release or a full release, but rather an update to the mapping table that shows the relationship between the CCM controls and other industry-accepted security standards, regulations, and frameworks3.

D. technical change (revision, addition, or deletion) of a number of controls that is greater than 10% compared to the previous full release: A technical change (revision, addition, or deletion) of a number of controls that is greater than 10% compared to the previous full release is a significant change that affects the content and scope of the CCM. A technical change (revision, addition, or deletion) of a number of controls that is greater than 10% compared to the previous full release requires a full release, not a dot release, and is denoted by an integer number, such as CCM v3 or CCM v42.

Cloud Controls Matrix (CCM) - CSA

The CSA Cloud Controls Matrix (CCM) V4: Raising the cloud security bar

Cloud Security Alliance Releases New Cloud Controls Matrix Auditing Guidelines

When auditing a public cloud, it is essential to review areas such as Identity and Access Management (IAM) and data protection. IAM involves ensuring that only authorized individuals have access to the cloud resources, and that their access is appropriately managed and monitored. This includes reviewing user authentication methods, access control policies, role-based access controls, and user activity monitoring1.

Data protection is another critical area to review. It involves ensuring that the data stored in the public cloud is secure from unauthorized access, breaches, and leaks. This includes reviewing data encryption methods, data backup and recovery processes, data privacy policies, and compliance with relevant data protection regulations1.

While the other options may also be relevant in certain contexts, they are not as universally applicable as IAM and data protection for auditing a public cloud. Source code reviews and hypervisor (option B), patching and configuration (option C), and vulnerability management and cybersecurity reviews (option D) are important but are more specific to certain types of cloud services or deployment models. References:

A RACI chart is a tool used to clarify the roles and responsibilities in processes, projects, or operations. In the context of cloud compliance, documenting these responsibilities in a RACI chart ensures that all parties within the enterprise are aware of their specific obligations regarding compliance with laws and regulations. This helps in creating a clear, organized view of how each part of the organization contributes to overall compliance, facilitating better coordination and accountability.

References = The answer is informed by general best practices in cloud compliance and governance, which recommend the use of RACI charts or similar tools to delineate responsibilities clearly. While I can’t reference specific documents from the CCAK or related resources, these practices are widely accepted in the field of cloud security and compliance.

Exception reporting is crucial for maintaining effective cloud application controls within an organization. It involves monitoring and reporting deviations from standard operating procedures, which can indicate potential security issues. This proactive approach allows organizations to address vulnerabilities promptly before they can be exploited. Exception reporting is a key component of a robust security posture, as it provides real-time insights into the operational effectiveness of controls and helps maintain compliance with security policies.

References = The importance of exception reporting is highlighted in best practices for cloud security, which emphasize the need for continuous monitoring and immediate response to any anomalies detected in cloud applications

Access controls are the aspect of Software as a Service (SaaS) functionality and operations that the cloud customer is responsible for and should be audited. Access controls refer to the methods and techniques that verify the identity and access rights of users or devices that access or use the SaaS application and its data. Access controls may include credentials, policies, roles, permissions, tokens, multifactor authentication, single sign-on, etc. The cloud customer is responsible for ensuring that only authorized and legitimate users or devices can access or use the SaaS application and its data, as well as for protecting the confidentiality, integrity, and availability of their data. The cloud customer should also monitor and audit the access and usage of the SaaS application and its data, as well as any incidents or issues that may affect them123.

Source code reviews (A) are not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Source code reviews refer to the processes and practices that examine the source code of software applications or systems to identify errors, bugs, vulnerabilities, or inefficiencies that may affect their quality, functionality, or security. Source code reviews are mainly under the responsibility of the cloud service provider, as they own and operate the software applications or systems that deliver SaaS services. The cloud customer has no access or control over these aspects123.

Patching (B) is not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Patching refers to the processes and practices that ensure the security, reliability, and performance of the cloud infrastructure, platform, or software. Patching involves the use of updates or fixes to address vulnerabilities, bugs, errors, or exploits that may compromise or affect the functionality of the cloud components. Patching is mainly under the responsibility of the cloud service provider, as they own and operate the cloud infrastructure, platform, or software. The cloud customer has limited or no access or control over these aspects123.

Vulnerability management (D) is not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Vulnerability management refers to the processes and practices that identify, assess, treat, monitor, and report on the risks that affect the security posture of an organization or a domain. Vulnerability management involves the use of tools or techniques to scan, analyze, prioritize, remediate, or mitigate vulnerabilities that may expose an organization or a domain to threats or attacks. Vulnerability management is mainly under the responsibility of the cloud service provider, as they own and operate the cloud infrastructure, platform, or software. The cloud customer has limited or no access or control over these aspects123. References :=

 An example of availability technical impact is a distributed denial of service (DDoS) attack that renders the customer’s cloud inaccessible for 24 hours. Availability technical impact refers to the effect of a cloud security incident on the protection of data and services from disruption or denial. Availability is one of the three security properties of an information system, along with confidentiality and integrity.

Option A is an example of availability technical impact because it shows how a DDoS attack, which is a type of cyberattack that overwhelms a system or network with malicious traffic and prevents legitimate users from accessing it, can cause a severe and prolonged disruption of the customer’s cloud services. Option A also implies that the customer’s organization depends on the availability of its cloud services for its core business operations.

The other options are not examples of availability technical impact. Option B is an example of confidentiality technical impact, which refers to the effect of a cloud security incident on the protection of data from unauthorized access or disclosure. Option B shows how a breach of customer personal data from an unsecured server, which is a type of data leakage or exposure attack that exploits the lack of proper security controls on a system or network, can cause a violation of the privacy and security of the customer’s data. Option C is an example of integrity technical impact, which refers to the effect of a cloud security incident on the protection of data from unauthorized modification or deletion. Option C shows how an administrator inadvertently clicking on phish bait, which is a type of social engineering or phishing attack that tricks a user into clicking on a malicious link or attachment, can expose the company to a ransomware attack, which is a type of malware or encryption attack that locks or encrypts the data and demands a ransom for its release. Option D is also an example of integrity technical impact, as it shows how a hacker using a stolen administrator identity, which is a type of identity theft or impersonation attack that exploits the credentials or privileges of a legitimate user to access or manipulate a system or network, can alter the discount percentage in the product database, which is a type of data tampering or corruption attack that affects the accuracy and reliability of the data. References :=
