Auditor Translation Guide: How to speak "Auditor Language" using key terms like correlated, continuously, and exceptions.
💡 Frequently Asked Questions
Q: What is NIST SP 800-53 CM-3 Enhancement 7?
A: CM-3(7) requires organizations to review changes to the system at an organization-defined frequency or under specific circumstances to determine whether unauthorized changes have occurred.
Q: How do you satisfy CM-3(7) with CI/CD automation?
A: Instead of manual weekly CAB meetings, map every production deployment to a pull request, commit hash, and automated pipeline execution. Set up continuous monitoring to alert security teams immediately when an unmapped/unauthorized change occurs (exception reporting).
