Potential false positivesedit

Sign-ins using PowerShell may be done by a system or network administrator. Verify whether the username, hostname, and/or resource name should be signing into your environment. Sign-ins from unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
