ASL AWS Disable Bucket Versioning

Summary
The ASL AWS Disable Bucket Versioning detection rule identifies when an AWS S3 bucket versioning is disabled by a user. This rule utilizes AWS CloudTrail logs to track `PutBucketVersioning` API calls where the `VersioningConfiguration.Status` is set to `Suspended`. Suspending bucket versioning is particularly alarming as it can prevent recovery from ransomware attacks by making it impossible to retrieve deleted or modified objects. The search queries map out the user actions, pinpoint the bucket affected, and log relevant details such as user account IDs, source IP addresses, and the time of the event. Administrators must carefully consider the implications of disabling versioning, as it may expose the organization to data loss risks. This detection rule is vital for maintaining data integrity and availability within AWS environments.
