PCI SSC QSA_New_V4 Dumps Questions Answers

Protecting the Database Server

PCI DSS v4.0 requires that systems storing cardholder data, such as database servers, must not be directly accessible from untrusted networks (Requirement 1.3).

The database server should be behind network security controls like firewalls and placed in a segmented network isolated from untrusted networks​​.

Segmentation Best Practices

The web server, which interfaces with external users, can remain accessible from the Internet but should reside in a DMZ to prevent direct access to the internal network.

This separation protects the database server from external threats while maintaining system functionality​​.

Incorrect Options

Option A: Combining the web and database servers increases the attack surface and violates best practices.

Option C: Moving the web server to the internal network exposes the internal environment.

Option D: Segmentation is critical, but the reason is not solely to allow more concurrent connections.

Requirement Context:

PCI DSS Requirement 12.5 mandates that security policies and operational procedures are not only documented but also distributed to relevant parties to ensure clarity and compliance.

Importance of Distribution and Awareness:

All affected parties, including employees, contractors, and third parties with access to the cardholder data environment (CDE), must receive and understand the policies. This ensures they adhere to the security measures​​.

Review and Updates:

Security policies must be kept up to date and reviewed at least annually or after significant changes in the environment. While other options such as encryption or restricted access are important for security, the critical focus is on distribution and awareness to ensure operational effectiveness​​.

Testing and Validation:

During assessments, QSAs validate the implementation by examining training records, communication logs, and acknowledgment forms signed by affected parties​​.

Relevant PCI DSS v4.0 Guidance:

Section 12.5.1 of PCI DSS v4.0 outlines that the dissemination of policies must ensure that all personnel understand their roles in securing the environment​​.

Customized Approach Overview:

Under PCI DSS v4.0, entities can use a Customized Approach to meet requirements by implementing controls tailored to their environment. This allows flexibility while still achieving the intent of the security requirement.

Role of Assessors:

Assessors (QSAs) are responsible for evaluating both the implementation of customized controls and ensuring these controls fulfill the security objectives of the PCI DSS requirements​​.

QSAs must document the evaluation, evidence reviewed, and results in the Report on Compliance (ROC).

Controls Matrix and Targeted Risk Analysis (TRA):

The Controls Matrix and TRA are key components of the Customized Approach. QSAs assist in verifying the accuracy and completeness of these tools during assessments​​.

Documenting in the ROC:

The ROC must include a narrative explaining the assessor’s findings regarding the customized control, validation methods, and any evidence collected​.

Relevant PCI DSS v4.0 Guidance:

Appendix D and E of the PCI DSS v4.0 ROC Template emphasize that QSAs can evaluate and confirm adherence to the Customized Approach provided this is documented comprehensively in the ROC​.
