Coding Tech · Beginner ·🔧 Backend Engineering ·6mo ago

About this lesson

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. --- Timestamps: 0:00 - Introduction: Why API Security Matters 1:38 - Measure 1: HTTPS & TLS Encryption 3:01 - Measure 2: Authentication (JWTs & OAuth) 4:26 - Measure 3: Authorization & BOLA Prevention 6:00 - Measure 4: Rate Limiting 7:31 - Measure 5: Input Validation 9:15 - Measure 6: SQL Injection Prevention 11:05 - Measure 7: CORS Configuration 12:40 - Measure 8: CSRF Protection 14:11 - Measure 9: XSS Prevention 15:52 - Measure 10: Security Headers 17:36 - Your Security Checklist
