As part of our ongoing maintenance and improvement of rules and rule bundles, we are updating rules related to AWS CloudTrail log metric filters. This change will offer a shift towards organization-level CloudTrail configurations, enabling enhanced security and manageability for your resources.

Please be aware that the existing rules will be deprecated in the following bundles:

• AWS FTR version 1.0.0
• CIS Benchmark from version 1.1.0 to 1.5.0
• Organization Rules
• S3 Best Practice version 1.0 and version 1.1
• Stax Foundation Compliance version 1.0

The deprecated rules are as follows:

• Ensure a log metric filter and alarm exist for AWS Config configuration changes, 
• Ensure a log metric filter and alarm exist for AWS Management Console authentication failures, 
• Ensure a log metric filter and alarm exist for Management Console sign-in without MFA, 
• Ensure a log metric filter and alarm exist for changes to Network Access Control Lists (NACL), 
• Ensure a log metric filter and alarm exist for changes to network gateways,
• Ensure a log metric filter and alarm exist for CloudTrail configuration changes,
• Ensure a log metric filter and alarm exist for disabling or scheduled deletion of customer-created CMKs, 
• Ensure a log metric filter and alarm exist for IAM policy changes, 
• Ensure a log metric filter and alarm exist for route table changes, 
• Ensure a log metric filter and alarm exist for S3 bucket policy changes, 
• Ensure a log metric filter and alarm exist for security group changes, 
• Ensure a log metric filter and alarm exist for unauthorized API calls, 
• Ensure a log metric filter and alarm exist for usage of root user credentials, 
• Ensure a log metric filter and alarm exist for VPC changes

The newly introduced rules will take their place with the following rule names respectively:

• CloudTrail should have a log metric filter for AWS Config changes,
• CloudTrail should have a log metric filter for Console authentication failures,
• CloudTrail should have a log metric filter for Console sign-in without MFA,
• CloudTrail should have a log metric filter for NACL changes,
• CloudTrail should have a log metric filter for Network Gateway changes,
• CloudTrail should have a log metric filter for CloudTrail configuration changes,
• CloudTrail should have a log metric filter for scheduled deletion of customer-created CMKs,
• CloudTrail should have a log metric filter for IAM policy changes,
• CloudTrail should have a log metric filter for route table changes,
• CloudTrail should have a log metric filter for s3 bucket policy changes,
• CloudTrail should have a log metric filter for security group changes,
• CloudTrail should have a log metric filter for unauthorized API calls,
• CloudTrail should have a log metric filter for root user credentials,
• CloudTrail should have a log metric filter for VPC changes

Please note that the check history for the deprecated rules will not be kept.
