Security Architecture

Authentication & Authorization

Current State

• Backend enforces Auth0 JWT validation via Fastify using @fastify/jwt and get-jwks (JWKS-based public key retrieval).
• Protected endpoints require a valid Authorization: Bearer <token> header and populate request.user on success.

Protected Endpoints (JWT required)

• Vehicles CRUD endpoints (/api/vehicles, /api/vehicles/:id)
• Vehicles dropdown endpoints (/api/vehicles/dropdown/*)
• Fuel logs endpoints (/api/fuel-logs*)
• Stations endpoints (/api/stations*)

Unauthenticated Endpoints

• None

Data Security

VIN Handling

• VIN validation using industry-standard check digit algorithm
• VIN decoding via integrated MVP Platform service (FastAPI) with shared database and caching
• No VIN storage in logs (mask as needed in logging)

Database Security

• User data isolation via userId foreign keys
• Soft deletes for audit trail
• No cascading deletes to prevent data loss
• Encrypted connections to PostgreSQL

Infrastructure Security

Docker Security

• Development containers run as non-root users
• Network isolation between services
• Environment variable injection for secrets
• No hardcoded credentials in images

API Client Security

• Separate authenticated/unauthenticated HTTP clients where applicable
• Request/response interceptors for error handling
• Timeout configurations to prevent hanging requests
• Auth token handling via Auth0 wrapper
