Potential false positivesedit

Suspending the recording of a trail may be done by a system or network administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. Trail suspensions from unfamiliar users or hosts should be investigated. If a known behavior is causing false positives, it can be excluded from the rule.

Investigation guideedit
