Understanding API Security

API Security is the practice of protecting application programming interfaces (APIs) from attacks and misuse across their lifecycle. It covers authentication and authorization (using protocols such as OAuth 2.0 and JSON Web Tokens), input validation, rate limiting, encryption of data in transit, and monitoring and logging of API traffic. Strong API security defends against threats like broken authentication, injection, excessive data exposure, and denial-of-service attacks against backend services.
