What is the purpose of a Control Assessment Guide (CAG)?

The purpose of a Control Assessment Guide (CAG) is to offer guidelines for security control assessments. A CAG is a structured document that supplies specific criteria, methodologies, and best practices to effectively assess the implementation and effectiveness of security controls within an organization. It serves as a roadmap for assessors to evaluate whether the security measures in place meet established standards and are functioning as intended.

By outlining the assessment process, such as what to look for and how to document findings, a CAG helps ensure a consistent approach across different assessments, thereby supporting the organization in identifying vulnerabilities and compliance with relevant security frameworks and regulations. This is essential for maintaining robust security posture and protecting sensitive information. The focus is on assessment methodologies and criteria rather than legalities, penalties, or training programs, which is why the other answer choices do not accurately reflect the primary function of a CAG.
