Episode 59 — API Security: Authentication, Authorization and Rate Limiting

APIs are the glue of modern cloud applications, and their security is a top priority. In this episode, we explore how authentication and authorization work for APIs, highlighting practices such as OAuth 2.0, API gateways, and fine-grained permissions. We also explain why rate limiting and throttling are essential to preventing abuse and denial-of-service conditions.

On the CCSP exam, API security often appears in scenario questions where misconfigured endpoints or over-privileged tokens lead to risk. By studying these principles, you’ll be ready to secure APIs effectively and demonstrate knowledge of one of the most exam-relevant and real-world topics in application security.
