Selectively log network activity events by identity in AWS CloudTrail

Configure CloudTrail to use UserIdentity filtering for network activity events to log only relevant events, such as access denied events from untrusted identities, thereby reducing logging costs and improving security monitoring efficiency.

Adopt UserIdentity filtering in CloudTrail to provide fine-grained control over network activity event logging, enabling better security posture and cost optimization for the platform.

Evaluate implementing UserIdentity filtering in CloudTrail to enhance security by selectively logging network activity events, reducing logging costs, and minimizing operational noise, leading to improved data perimeter strategies and better detection of unauthorized access attempts.
