Potential false positives

edit

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