3.12 Security Assessment5 pts

3.12.3 — Monitor controls continuously

Monitor security controls on an ongoing basis to ensure the continued effectiveness of the controls.

You monitor controls on an ongoing basis, not just at assessment time.

What it actually means

Continuous monitoring — keeping an eye on whether controls stay effective between formal assessments. It's the operational habit that keeps your score from drifting (and keeps your annual affirmation honest). Often realized through your SIEM, EDR, compliance dashboards, and periodic checks.

Pass or fail — an assessor needs a "yes" to each
