Potential false positivesedit

An RDS security group may be created by a system or network administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. Security group creations by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
