About

Identifies when object versioning is suspended for an Amazon S3 bucket. Object versioning allows for multiple versions of an object to exist in the same bucket. This allows for easy recovery of deleted or overwritten objects. When object versioning is suspended for a bucket, it could indicate an adversary's attempt to inhibit system recovery following malicious activity. Additionally, when versioning is suspended, buckets can then be deleted.
