What it detects
This rule flags process creation events where gpresult.exe is executed with parameters used to display the Resultant Set of Policy (RSoP) output. Attackers may use this information to understand effective Group Policy settings on a host and guide further discovery or targeting. The detection relies on Windows command-line telemetry to match gpresult.exe execution with the expected /z and /v arguments.
