What it detects

This rule flags process executions of dsacls.exe where the command line includes /G and permission tokens such as GR, GE, GW, GA, WP, or WD. Granting broad or high-privilege rights can enable privilege escalation and stealthy access persistence. The detection relies on Windows process creation telemetry, specifically the image name and command-line content.
