name: CloudTrail S3 Object Lock
|
|
author: princechaddha

description: |
|
|
Ensure Amazon CloudTrail S3 buckets have Object Lock enabled to prevent log deletion and ensure regulatory compliance.
|
|
impact: |
|
|
Without Object Lock, S3 objects such as CloudTrail logs can be deleted, compromising audit trails and violating compliance requirements.
|
|
remediation: |
|
|
Enable S3 Object Lock in Governance mode with a retention period that meets your compliance requirements for CloudTrail S3 buckets.
