Authorization Boundary Clinic
Enforce tenant, object, action, and administrative policy. Attempt horizontal and vertical privilege escalation through every route.
Required evidence
Submit diagrams, versioned configuration, runnable positive and negative tests, audit events, one rejected design, remediation record, and residual-risk owner. Scanner output without mechanism-level triage does not pass.
Oral defense
Name the attacker and asset, explain the exact control property, demonstrate a denied misuse case, and execute revocation or safe recovery.
Source backbone
Use NIST SP 800-63, OWASP ASVS, relevant RFCs, and Building Secure and Reliable Systems.
