name: CloudTrail S3 Logging
|
|
author: princechaddha

severity: high
|
|
description: |
|
|
Ensure AWS CloudTrail logs are captured in S3 buckets with Server Access Logging enabled for audit and forensic purposes.
|
|
impact: |
|
|
Without S3 Server Access Logging for CloudTrail, tracking unauthorized access or modifications to CloudTrail logs becomes difficult, impacting incident response and forensic analysis.
|
|
remediation: |
|
|
Enable Server Access Logging on the S3 bucket used by CloudTrail. Configure the logging feature to capture all requests made to the CloudTrail bucket.
