The API Gateway must audit authentication and authorization information.

The API Gateway must audit authentication and authorization information to ensure robust security, compliance, and accountability in access control. As the central entry point for all incoming API requests, the gateway is responsible for verifying the identity of users and ensuring they have the necessary permissions to access specific resources. By auditing authentication and authorization events, the gateway creates an audit trail that helps track and verify who accessed the API, when, and with what permissions. This is crucial for identifying and responding to potential security threats, such as unauthorized access attempts or privilege escalation. Auditing also helps detect suspicious patterns, such as repeated failed login attempts or attempts to access restricted endpoints, which could indicate an ongoing attack.
