Security - Auth Module

Report vulnerabilities via project-level SECURITY.md.

Security Scope

Security in the auth module focuses on fail-closed identity validation, resilient credential/token handling, replay/revocation controls, and continuous trust verification boundaries.

Threat Model

Threat	Current Mitigation Surface
forged or tampered tokens	signature/claim validation and revocation checks in token validators
credential brute-force and replay	rate-limiting, replay-cache, and blacklist/session controls
provider-integration abuse	explicit protocol adapters with structured validation and failure handling
cross-realm identity confusion	federated identity and principal validation boundaries
long-lived trust drift	zero-trust continuous verification and session enforcement paths

Implemented Security Controls

• authentication adapters are explicit and method-specific.
• token/session flows include revocation/replay-aware support surfaces.
• audit and metrics paths provide security-relevant observability.
• policy/trust checks can gate downstream execution before business handlers.

Security Follow-ups

• continue hardening distributed revocation and federation edge behavior.
• maintain strict handling for optional provider degradation scenarios.
• keep threat-specific diagnostics and enforcement behavior testable and observable.
