# 🛡️ Luxe Platform - Enterprise Security Model & Audit Checklist

## Security Mitigations & Standards

### 1. OWASP Top 10 Protections
- **SQL Injection**: Handled natively by Prisma ORM prepared statements and parameterized queries.
- **Cross-Site Scripting (XSS)**: Handled by `@fastify/helmet` setting strict HTTP security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options).
- **Cross-Site Request Forgery (CSRF)**: Refresh tokens are stored in `HttpOnly`, `SameSite=Strict`, `Secure` cookies.
- **Brute Force Protection**: Rate limiting enforced at 100 requests / 15 minutes per IP via `@fastify/rate-limit`, plus progressive account login lockouts.

### 2. Password & Encryption Standards
- Password Hashing: **Argon2id** with 64MB memory cost, 3 iterations, and 4 degree parallelism.
- Tokens: **JWT (ES2022 / RS256 or HS256)** short-lived access tokens (15m) with refresh token rotation (7d).

### 3. Dynamic Policy RBAC
- Role-based and Permission-based dynamic policy evaluation on every sensitive endpoint.
- Database-driven permissions preventing hardcoded authorization checks.

### 4. Audit Logging
- Every sensitive action (Status updates, User suspensions, Verification approvals, Balance adjustments) records an immutable `AuditLog` entry tagged with IP, User Agent, Timestamp, and Admin ID.
