What is API Security?
What does 'API Security' mean?
Protection aimed specifically at API endpoints rather than browser-facing pages. It typically covers discovering which APIs exist, validating requests against a schema, enforcing authentication and rate limits, and blocking abuse such as credential stuffing or scraping. APIs are targeted because they expose data and business logic directly, often with no user interface in front of them.
