Potential false positives

edit

The GuardDuty detector may be deleted by a system or network administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. Detector deletions from unfamiliar users or hosts should be investigated. If a known behavior is causing false positives, it can be excluded from the rule.
