CM.L2-3.4.3 — Track, review, approve or disapprove, and log changes to organizational systems.

What this control requires

Track, review, approve or disapprove, and log changes to organizational systems.

Source: CMMC L2 v2.13 CM.L2-3.4.3 / NIST SP 800-171 R2 3.4.3 (official control text).

Why this matters

Uncontrolled changes to production systems are a leading cause of outages, security gaps, and compliance violations. This control requires formal change management: every modification to infrastructure, applications, configurations, or baselines must be documented, justified, approved by authorized personnel, and logged with a complete audit trail. It prevents rogue changes, ensures rollback capability, creates accountability, and enables forensic investigation when incidents occur. Without this discipline, one unauthorized firewall rule change or undocumented patch can expose controlled unclassified information or disrupt mission-critical operations.

What evidence assessors expect

Assessors typically look for: PDF, screenshot, CSV export, configuration export. FORCE coaches you through the exact implementation steps and captures each artifact in-platform.
