📋 Implementări Complete

Backend

Autentificare JWT [C-01]

• ✅ backend/auth.py — JWT creation, validation, role checking
• ✅ /users/login — returnează TokenResponse (access_token, user_id, role, expirare 8h)
• ✅ Toți routers-ii — Depends(get_current_user) enforce
• ✅ Admin-only endpoints — Depends(get_current_admin)
• ✅ user_id — extras din JWT token, NU din request body [M-02]

Rate Limiting [H-02]

• ✅ slowapi integrat în requirements.txt
• ✅ /items/extract-label — @limiter.limit("10/minute") per IP
• ✅ Protecție împotriva spam pe AI endpoint

CORS Configurație [M-01]

• ✅ ALLOWED_ORIGINS din env var (fallback: localhost:3000, localhost:3002)
• ✅ Allow methods specific: GET, POST, PUT, DELETE, OPTIONS
• ✅ allow_credentials=True (valid cu specific origins)

Patch-uri Directe

• ✅ C-02 — Eliminat bypass password
• ✅ C-03 — Admin seed cu parola aleatoare
• ✅ H-01 — LDAP injection fix (escape_filter_chars)
• ✅ H-03 — MIME validation + 10MB limit upload
• ✅ M-03 — Logging LDAP via log.debug()

Frontend

JWT Handling [L-01]

• ✅ frontend/lib/auth.ts — saveToken, getToken, getAuthHeader, clearAuth
• ✅ Token storage — localStorage (inventory_token + inventory_user)
• ✅ Login page — salveaza TokenResponse din /users/login
• ✅ Token attach — Axios interceptor adauga Authorization: Bearer <token> pe toate cererile

Token Expiry [L-01]

• ✅ 401 Unauthorized → clearAuth() + redirect /login
• ✅ Interceptor pe axiosInstance
• ✅ Auto-logout pe expirare

Deployment

docker-compose.yml

• ✅ Backend environment vars: DATA_DIR, LOGS_DIR, ALLOWED_ORIGINS, JWT_SECRET_KEY
• ✅ Comentarii pentru producție
• ✅ Fallback values pentru development

Environment Variables

Var	Dev Default	Prod Requă	Purpose
ALLOWED_ORIGINS	localhost:3000, localhost:3002	SETEAZĂ!	CORS origins
JWT_SECRET_KEY	ephemeral (random)	SETEAZĂ!	JWT signing key
DATA_DIR	/app/data	-	Database location
LOGS_DIR	/app/logs	-	Logs location

🚀 Producție — Checklist

CRITICE — SETEAZĂ ÎNAINTE DE DEPLOY:

• JWT_SECRET_KEY — Generează cu openssl rand -hex 32
• ALLOWED_ORIGINS — Setează originile reale (ex: https://inventory.example.com)
• TLS/HTTPS — Caddy proxy configurate cu certificat valid
• Database backup — SQLite data/ mappped la persistent volume
• Logs rotation — logs/ mappped și monitorizate

RECOMANDATE:

• Setează log level → WARNING (nu DEBUG)
• Configureaza rate limiting pe alt nivel (nginx/cloudflare) pentru DDoS
• Monitorizare alertă pe 401 spikes (token expiry issues)
• Rotire periodică JWT_SECRET_KEY

📝 Testing Local

1. Run Development Setup

docker-compose up --build

2. Test Login

curl -X POST http://localhost:8000/users/login \
  -H "Content-Type: application/json" \
  -d '{"username": "Admin", "password": "<initial_password_din_logs>"}'

3. Test Protected Endpoint cu Token

curl -H "Authorization: Bearer <access_token>" \
  http://localhost:8000/items/

4. Test 401 (token expired)

curl -H "Authorization: Bearer invalid" \
  http://localhost:8000/items/
# Expect: 401 Unauthorized

5. Test Rate Limiting (extract-label)

# 11 cereri rapid — 11-a trebuie să fail cu 429
for i in {1..15}; do
  curl -X POST -F "file=@image.jpg" \
    -H "Authorization: Bearer <token>" \
    http://localhost:8000/items/extract-label
  sleep 0.1
done

✅ Validări

• ✅ Backend complet securizat
• ✅ Frontend token handling complet
• ✅ Rate limiting pe AI endpoint
• ✅ CORS configurable
• ✅ Toți routers-ii au auth enforcement
• ✅ Token expiry + redirect login
• ✅ Admin role check funcțional
• ✅ LDAP injection protected
• ✅ File upload validation
• ✅ Audit logging cu user_id din token

🎓 Lecții Învățate

1. CORS cu credentials=True — trebuie origins specifice, NU wildcard
2. Rate limiting — esențial pe endpoints costisitoare (AI)
3. JWT expirare — 8h e balanță bună între security + UX
4. user_id din token — elimină spoof-uri pe operații
5. Debug logging — PII leaks (DN-uri LDAP) dacă nu e grijă
