Define a documented break-glass procedure for emergency access that bypasses normal SSO when the IdP is unavailable, with strong MFA, monitoring and post-use review.
AWS Well-Architected Security Pillar SEC03-BP03 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of AWS Well-Architected Security Pillar your existing evidence covers. Hold NIST SP 800-53 Rev 5 and 52 of 63 AWS Well-Architected Security Pillar controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 0 were rejected on the NIST SP 800-53 Rev 5 pair alone.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
