CloudTrail should use Customer managed keys to encrypt the logs

Property

Service	cloudtrail
Provider	AWS
Vulnerability Type	omission

Description#

CloudTrail logs are being encrypted using AWS-managed keys instead of customer-managed keys, which limits the ability to control key policies, permissions, and rotation. This reduces the flexibility and security of sensitive audit log data.

Impact#

Without customer-managed keys, organizations cannot enforce fine-grained access controls or customize key management practices for CloudTrail logs. This increases the risk of unauthorized access to audit trails and may result in non-compliance with security or regulatory requirements.

Resolution#

Use Customer managed key
