2. Authentication – JWTs, token expiration, secret storage, OAuth 2.0
3. Authorization – Authentication vs authorization, BOLA attacks, RBAC
4. Rate Limiting – Token bucket algorithm, preventing brute force & DDoS
5. Input Validation – Schema validation, type checking, preventing overflow attacks
6. Injection Prevention – SQL injection, parameterized queries, NoSQL injection
7. CORS – Cross-origin resource sharing, preflight requests, proper configuration
