The AWS S3 Delete Objects Detection rule monitors the deletion of multiple objects from Amazon S3 buckets, which could signify unauthorized or suspicious actions taken by users. The detection utilizes AWS CloudTrail logs to actively identify events where the 'DeleteObjects' API call is executed. The rule is triggered whenever one or more objects are deleted, with a defined threshold of one deletion event for the rule to activate. Upon detection, a medium severity alert is generated, prompting an investigation into the user's actions. A series of investigative steps are suggested in the runbook to ascertain if the deletion was authorized and to check for potential misuse of credentials. This helps to mitigate risks related to data loss and ensures the integrity of S3 bucket access controls. The rule is essential for organizations relying on AWS S3 for storage to prevent data breaches and unauthorized deletions.
