Potential false positivesedit
Role deletions may be done by a system or network administrator. Verify whether the user email, resource name, and/or hostname should be making changes in your environment. Role deletions by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
