NSK300 Netskope Certified Cloud Security Architect Exam Questions and Answers

Netskope Cloud Security Posture Management (CSPM) allows for the creation of custom rules using Domain Specific Language (DSL) for all three major cloud platforms: AWS, Azure, and GCP. This capability is integral to CSPM and enables organizations to tailor their security posture assessments to their specific needs across different cloud environments.

To verify the previous value of a structured data field in Salesforce after an unauthorized change, you would use Skope IT with an Access Method of API Connector. This method allows you to search the Application Event Details for the ‘Old Value’ field. By filtering with the user details and the edit activity, you can pinpoint the exact change and retrieve the original value of the field.

To integrate Netskope with a third-party DLP engine using ICAP, you must configure the Netskope Secure Forwarder.

Secure Forwarder is the only Netskope component that supports:

ICAP communication

Forwarding inline web traffic to external DLP engines

Bidirectional ICAP requests/responses (REQMOD/RESPMOD)

This allows Netskope to send inspected content to your on-prem or third-party DLP appliance for additional scanning.

Why the other options are incorrect

A. On-Premises Log Parser (OPLP)Used for ingesting logs into Netskope — not for ICAP or traffic processing.

C. Netskope Cloud ExchangeUsed for integrations with SIEM, SOAR, ticketing, threat intel — not for inline DLP.

D. Netskope AdapterUsed mainly for SSPM/API integrations — not relevant for ICAP or external DLP engines.

When designing a policy for AWS S3 bucket scans with a custom DLP profile in Netskope, the available policy actions are Alert and Quarantine. These actions allow you to be notified when a policy violation occurs and to quarantine sensitive data to prevent potential data loss or exposure. The Alert action will notify the designated personnel or system when a match to the DLP profile is found during the scan. The Quarantine action will move the offending file to a secure location where it can be reviewed and dealt with appropriately1.

To accomplish the task of not steering specific domains to the Netskope Cloud while using the Explicit Proxy over Tunnel (EPoT) steering method, you would define exception domains in the PAC file (A). This is because the PAC file is used to specify which domains should bypass the proxy and connect directly, thus allowing for granular control over the traffic that is steered to Netskope1.

For a server subnet that is isolated and requires content filtering for any server that might access the Internet using a browser, the two Netskope deployment methods that would meet this requirement are:

B. Deploy Data Plane on Premises (DPoP) with a proxy configuration on the servers: Deploying DPoP would allow the isolated servers to connect to the Netskope cloud for content filtering through a proxy configuration. This setup would enable the servers to have controlled access to the Internet for content filtering purposes without requiring direct Internet access1.

C. Deploy IPsec or GRE tunnels in the segment to steer traffic from the servers to Netskope: By deploying IPsec or GRE tunnels, the traffic from the servers can be securely directed to Netskope for content filtering. This method is suitable for environments where servers do not have direct Internet access, as the tunnel provides a secure path for traffic to reach Netskope’s cloud services1.

These deployment methods are designed to work in environments with strict network isolation and provide the necessary content filtering capabilities for servers accessing the Internet.

Netskope supports automatic remediation of security violations through its Auto-Remediation frameworks, which are available in the public Netskope GitHub Open Source repository. These frameworks allow for the automatic mitigation of risks associated with security misconfigurations in your cloud environment. The Netskope Auto-Remediation framework for AWS, for example, deploys a set of AWS Lambda functions that query the Netskope API at scheduled intervals and automatically mitigates supported violations1. Similarly, there are frameworks for GCP and other cloud environments that follow the same principle2. This capability is particularly useful for low-risk environments where the security operations team’s workload can be reduced by automating the remediation process.

The Fast Scan component of Netskope Threat Detection utilizes Machine Learning to quickly detect and block malware in real-time. This is part of Netskope’s multi-layered security approach, which includes various engines to defend against a wide range of threats. The Fast Scan capability specifically leverages machine learning-based detection for rapid analysis and response to potential threats1.

Network Steering in Digital Experience Management is the appropriate Netskope monitoring tool for this scenario. It allows the Network Operations Center (NOC) to quickly view the status of the tunnels and provides an easy way to visualize the locations of the tunnels. This tool is designed to give a clear overview of network health and performance, which is essential for managing global connectivity and ensuring the reliability of the service.

To validate that the GRE tunnel is configured correctly and that traffic is flowing to Netskope, the correct statements are:

A: You can use your local router or network device to verify that keepalives are being received and traffic is flowing to Netskope. This is a standard method for checking the health and activity of a GRE tunnel.

C: You can verify that the tunnel is up and receiving traffic in the Netskope UI under Settings > Security Cloud Platform > GRE. This is a feature provided by Netskope to monitor the status of GRE tunnels directly from the Netskope interface12.

Statement B is incorrect because Netskope provides its own tools for monitoring the status of the tunnel. Statement D is incorrect because the Netskope Trust portal provides information on the overall service status and updates, not specific tunnel status3.

For a new Netskope tenant provisioned, to create a secure tenant configuration, you should consider changing the following default settings:

B. Change Untrusted Root Certificate to Block: This setting will ensure that any traffic coming from an untrusted root certificate is blocked, which is a critical security measure to prevent man-in-the-middle attacks and other types of cyber threats1.

D. Change “Disallow concurrent logins by an Admin” to Enabled: This setting will prevent multiple concurrent logins by the same admin account, which is an important security control to mitigate the risk of unauthorized access. If an admin’s credentials are compromised, this setting will help limit the potential damage by ensuring that only one session can be active at a time1.

These changes are part of the recommended security hardening guidelines for Netskope tenants to enhance the overall security posture of the tenant environment.

The reported issue of slow website and SaaS application access for users in the San Francisco branch office, despite being connected to a Netskope data plane in New York, can be attributed to the geographical distance between the user location and the data plane. The Netskope Security Cloud operates through a distributed network of data planes strategically placed in various regions. When users connect to a data plane that is geographically distant, it can result in latency due to longer network traversal times. In this case, the closest Netskope data plane to San Francisco might be unavailable or experiencing high load, leading to performance issues. To address this, consider optimizing data plane selection based on proximity to the user location or investigating any data plane availability or performance issues.

In the scenario where CASB traffic steering is enabled using the Netskope Client without a Real-time Protection policy being activated, the default behavior of the traffic is to allow and log it (B). This means that the traffic will not be blocked; instead, it will be permitted to pass through and will be recorded for monitoring and analysis purposes. This default setting ensures visibility into the traffic and user activities without immediately enforcing a block, allowing for a period of observation and policy tuning before potentially more restrictive actions are taken1.
