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 from unfamiliar users or hosts should be investigated. If a known behavior is causing false positives, it can be excluded from the rule.

The AWS Filebeat module must be enabled to use this rule.
