Certified Governance Risk and Compliance (CGRC) Practice Exam 2025 – All-in-One Guide to Master Your Certification!

The correct answer is based on the role that NIST SP 800-53A plays in the context of security control assessments. NIST SP 800-53A specifically focuses on the assessment and evaluation of the security controls outlined in NIST SP 800-53. It provides a standardized approach for assessing the effectiveness of those controls, helping organizations to determine whether they are meeting the necessary security requirements.

By using NIST SP 800-53A, organizations can follow a consistent methodology when conducting assessments, thus enabling them to identify weaknesses or gaps in their security measures more effectively. This systematic approach facilitates more rigorous and repeatable assessments, which is crucial for maintaining compliance with various regulatory and governance frameworks.

The other documents mentioned serve different purposes: NIST SP 800-37 relates to risk management framework processes, NIST SP 800-41 gives guidance on firewalls and intrusion detection, and NIST SP 800-66 focuses on health care information security. None of these directly address the assessment methodology for the controls specified in NIST SP 800-53, reinforcing why NIST SP 800-53A is the correct choice.
