Infrastructure Briefing — September 30, 2024
Cloud service providers with FedRAMP authorizations must complete their transition to NIST SP 800-53 Rev. 5 baselines by September 30, 2024, forcing security, compliance, and engineering teams to close control gaps now.
Executive briefing: The FedRAMP Program Management Office set September 30, 2024 as the deadline for all authorised cloud service providers to update their security packages to NIST SP 800-53 Rev. 5 controls. Joint Authorization Board (JAB) and agency-sponsored systems that miss the date risk corrective action plans, suspension, or revocation. Zeph Tech is partnering with platform and compliance teams to accelerate boundary documentation, logging upgrades, and supply-chain attestations.
Key transition milestones
- System Security Plan refresh. Providers must rebaseline SSPs, policies, and procedures to Rev. 5 requirements, including new supply-chain (SR) and privacy (PT) control families.
- Vulnerability scanning cadence. Rev. 5 enforces enhanced automated scanning (RA-5) and authenticated scanning coverage across infrastructure-as-code pipelines and container workloads.
- Third-party risk artefacts. Updated control baselines demand formal documentation of software supply chain due diligence, SBOM access, and dependency monitoring.
- Plan of Action & Milestones (POA&M). Outstanding gaps must be tracked against Rev. 5 controls with remediation dates and evidence for agency review.
Control alignment
- NIST SP 800-53 Rev. 5. Map new SR and PT families to existing vendor risk frameworks and zero-trust logging strategies.
- NIST SP 800-171 Rev. 3 draft. Harmonise Rev. 5 implementation with anticipated CMMC Level 2 updates to reduce duplicate assessment effort.
- ISO/IEC 27001:2022 Annex A. Crosswalk supplier security, logging, and configuration management controls to maintain multi-framework certification parity.
Implementation priorities
- Conduct delta assessments across Rev. 4-to-Rev. 5 control mappings, flagging documentation, tooling, and staffing gaps.
- Automate evidence collection for logging, vulnerability management, and incident response metrics using SIEM dashboards and ticketing integrations.
- Coordinate Third-Party Assessment Organisation (3PAO) readiness reviews with updated test cases covering SR, PT, and enhanced SC controls.
Enablement moves
- Brief executive sponsors on schedule risk, including potential customer impact if authorization statuses lapse post-deadline.
- Update customer assurance portals with Rev. 5-aligned control narratives, dependency lists, and penetration test reports.
- Embed Rev. 5 checks into CI/CD guardrails so configuration drift triggers automated change holds.
