API Security Best Practices Cheat Sheet
API Security Best Practices Cheat Sheet
11 PagesThis cheat sheet provides practical guidance for securing APIs, which are primary attack surfaces in modern apps. It stresses strong authentication (OAuth 2.0 with PKCE, MFA, key rotation) and strict authorization using RBAC and JWTs. Data protection is a major focus, with encryption in transit (TLS) and at rest (AES-256), along with key rotation. It also covers integrity (HMAC, digital signatures) and input validation to prevent injection attacks. The overarching message is to treat APIs as critical infrastructure and secure them with layered controls across authentication, authorization, and data protection.
