Potential false positivesedit

It’s strongly recommended that the root user is not used for everyday tasks, including the administrative ones. Verify whether the IP address, location, and/or hostname should be logging in as root in your environment. Unfamiliar root logins should be investigated immediately. If known behavior is causing false positives, it can be exempted from the rule.

Investigation guideedit
