CMMC Incident Response Timelines and Reporting Rules

The article explains CMMC incident response requirements across Levels 1–3, mapping Level 2 to NIST SP 800-171 R2 (IR 3.6.1–3.6.3) and Level 3 to NIST SP 800-172 enhancements (3.6.1e SOC 24/7, 3.6.2e CIRT deployable within 24 hours), while noting CMMC’s continued reliance on Rev 2 despite NIST’s Rev 3 update. It clarifies that DFARS 252.204-7012 sets the reporting timeline to 72 hours from discovery, broadens what constitutes a reportable “cyber incident,” and outlines the six incident response phases (preparation, detection, analysis, containment/eradication/recovery, user response). The piece also highlights that SOC/CIRT capabilities can be outsourced and includes promotional content for Ignyte’s compliance platform.
