The API Gateway must audit rate limiting events.

The API Gateway must audit rate-limiting events to ensure robust security, performance, and compliance across all APIs it manages. Rate-limiting is a critical mechanism to protect APIs from abuse, such as denial-of-service (DoS) attacks or excessive resource consumption by malicious users. By auditing these events, the gateway can track and log instances where rate limits are exceeded, providing valuable insights into abnormal traffic patterns or attempts to bypass limits. This helps identify potential threats early, allowing for timely interventions. Additionally, auditing rate-limiting events allows for detailed logging and reporting, which are essential for troubleshooting, performance monitoring, and ensuring fair usage of API resources.
