REST API Security

Definitions

1. The protection of RESTful APIs against authentication flaws, authorization bypass, injection, excessive data exposure, abuse, and misuse of tokens or request semantics. REST API security depends on more than HTTPS; it requires careful design of identity, validation, rate limits, and object-level access control.

   In plain English: Security for web APIs that use REST-style requests and responses.

   Example: "The platform passed transport encryption checks but still failed REST API security because any authenticated user could request another customer's object by ID."
