This detection rule monitors changes to the Windows Registry that indicate the enabling of the PowerShell script execution policy, specifically via the key located at `\Policies\Microsoft\Windows\PowerShell\EnableScripts`. The detection mechanism triggers when the specified registry entry is set to a DWORD value of `0x00000001`, which signifies that script execution is permitted. Enabling script execution can pose security risks as it allows potentially malicious scripts to run, hence the importance of monitoring this change to maintain system integrity and safety.
