# Enterprise Security Module — Build Progress

## Status: ✅ COMPLETE (All Sections)

- [x] **Section 1:** Prisma Schema (SecurityLog + enhanced AuditLog) + Security Module Foundation (constants, interfaces, utils)
- [x] **Section 2:** Password Security (Argon2id hashing, password policy validator) — wired into AuthService/AuthModule
- [x] **Section 3:** JWT + Refresh Token Hardening (SHA-256 at rest, token reuse detection, secure cookies, session binding, JWT claims hardening)
- [x] **Section 4:** Rate Limiting (global + route-specific, custom ThrottlerGuard, proxy IP extraction, admin allowlist, 429 response with Retry-After)
- [x] **Section 5:** XSS Protection (Helmet strict CSP, body sanitizer middleware, response sanitizer interceptor, HSTS, security headers)
- [x] **Section 6:** CSRF Protection (HMAC token service, CSRF guard, double-submit cookie, JWT CSRF rationale)
- [x] **Section 7:** SQL Injection Protection (input validator, parameterized query util, Prisma ORM enforcement)
- [x] **Section 8:** Audit Logs + Security Monitoring (audit/security loggers, interceptors, monitoring service, admin controller)
- [x] **Section 9:** RBAC + Permission Guard Enhancement (role hierarchy, enhanced roles guard, permission decorator)
- [x] **Section 10:** HTTPS + Deployment (Nginx config, Let's Encrypt SSL docs, secure cookies guide)
- [x] **Section 11:** Tests (unit tests for password, CSRF, token security, rate limiting, XSS, SQL injection, audit, RBAC)
- [x] **Section 12:** Documentation (SECURITY.md — full security architecture, OWASP compliance, component explanations)

## Notes
- All secrets sourced from environment variables only (never hardcoded).
- All DB access via Prisma ORM; raw SQL only with parameterized queries.
- Prisma migration required after schema changes: `npx prisma migrate dev --name add_security_logs`
- Run `npx prisma generate` to regenerate Prisma client after schema changes
- Tests use Jest globals (`describe`, `it`, `expect`, `jest`) — these resolve at runtime, not compile-time
