API Security: 10 Essential Measures Every Developer Must Know
In 2025, 84% of organizations experienced at least one API security incident. API calls now make up 71% of web traffic, and API breaches leak 10x more data than average security incidents. This video covers the 10 battle-tested security measures that will protect your applications from the most common and devastating attacks.
What you'll learn:
1. HTTPS & TLS - Encrypt all traffic, TLS 1.3, certificate verification
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
8. CSRF Protection - Token-based defense, SameSite cookies
9. XSS Prevention - Stored/Reflected/DOM-based XSS, sanitization, CSP headers
10. Security Headers - CSP, X-Frame-Options, HSTS, X-Content-Type-Options
Master all 10 measures and you'll block the vast majority of attacks before they ever reach your data.
