FedRAMP incident-reporting regime: CSPs must report incidents to: (a) the FedRAMP PMO; (b) agency customer points-of-contact; (c) US-CERT (CISA) per the FISMA incident-reporting requirements. INCIDENT TYPES requiring reporting: confirmed incidents affecting CSP system + customer agency data + Personally Identifiable Information (PII) + Controlled Unclassified Information (CUI) + cryptographic-system compromise + significant ConMon-detected anomalies. INCIDENT REPORTING TIMELINES per FedRAMP guidance + the 2024 OMB M-24-15: initial notification within 1 hour of confirmation for high-severity incidents (vs the prior 4-hour requirement); status updates + final reports per FedRAMP PMO + agency expectations + the CIRCIA (Cyber Incident Reporting for Critical Infrastructure Act of 2022) Final Rule (effective 2026) which extends to FedRAMP-authorized CSPs serving critical infrastructure agencies. INCIDENT RESPONSE PLAN (IRP) is part of the FedRAMP authorization package + must be reviewed annually + tested per the Contingency Plan testing requirements.
