API Security - 10 Essential Measures Every Developer Must Know

Learn ten critical security measures to protect your APIs from the most common and devastating attacks in this comprehensive 19-minute video tutorial. Discover why API security is crucial given that 84% of organizations experienced API security incidents in 2025, with API calls comprising 71% of web traffic and API breaches leaking 10 times more data than average security incidents. Master HTTPS and TLS encryption implementation including TLS 1.3 and certificate verification to secure all traffic. Understand authentication mechanisms through JWTs, token expiration strategies, secure secret storage, and OAuth 2.0 implementation. Explore authorization concepts including the distinction between authentication and authorization, BOLA (Broken Object Level Authorization) attack prevention, and Role-Based Access Control (RBAC). Implement effective rate limiting using token bucket algorithms to prevent brute force attacks and DDoS attempts. Apply robust input validation techniques including schema validation, type checking, and overflow attack prevention. Prevent injection attacks by understanding SQL injection vulnerabilities, implementing parameterized queries, and addressing NoSQL injection risks. Configure Cross-Origin Resource Sharing (CORS) properly including preflight requests and secure configuration practices. Implement CSRF (Cross-Site Request Forgery) protection through token-based defense mechanisms and SameSite cookie configurations. Prevent Cross-Site Scripting (XSS) attacks by understanding stored, reflected, and DOM-based XSS vulnerabilities, implementing proper sanitization, and using Content Security Policy headers. Deploy essential security headers including CSP, X-Frame-Options, HSTS, and X-Content-Type-Options to create multiple layers of protection for your applications.
