Potential false positivesedit

Bucket components may be deleted by a system or network administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. Bucket component deletions by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
