Phase 9 Sprint 9.1 - Red Team Validation Architecture

Summary

Added a dedicated red-team simulation suite as a release-gating security control within CI.

Threat Model

• CI must treat incoming changes as untrusted and reject any build that permits critical attack-path regressions.

Attack Vectors Considered

• Replay and signature bypass.
• Service identity spoofing / MITM fingerprint mismatch.
• Cross-tenant access.
• Queue poisoning.
• Tamper log integrity bypass.
• Rate limit exhaustion.

Mitigations Implemented

• Phase 9.1 simulation suite executes adversarial request and tampering scenarios.
• Security workflow now includes red-team simulations in required regression gate.
• Promotion gate remains fail-closed when any simulation test fails.

Residual Risk

• This sprint validates known controls; emerging vectors still require periodic suite expansion.

Future Improvements

• Add attack replay corpus and scenario versioning.
• Add federation-specific replay and key-rotation adversarial tests.
