API Security

Overview

APIs are the primary attack surface of modern applications. As architectures shift toward microservices, serverless functions, and third-party integrations, the number of exposed API endpoints grows dramatically. Every endpoint is a potential entry point for attackers. Securing APIs requires a layered approach that includes transport security, authentication, authorization, input validation, rate limiting, and proper response handling. A single misconfigured header or overly permissive CORS policy can expose an entire system.

Security Headers

Security headers instruct browsers and clients on how to handle responses, significantly reducing the attack surface for common web-based attacks.
