Potential false positivesedit
It’s strongly recommended that the root user is not used for everyday tasks, including administrative tasks. 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 a known behavior is causing false positives, it can be excluded from the rule.
Investigation guideedit
The AWS Filebeat module must be enabled to use this rule.
