Why Execution Policy is not Security
Written on January 20, 2016

The PowerShell execution policy seems to be widely misunderstood. It is not there to stop administrators doing things. At all. This is why:

C:\> .\badscript.ps1

Cool! Can’t run the script! Right? Wrong.

C:\> Invoke-Expression (Get-Content .\badscript.ps1)

This is one of just many, many, ways to bypass the execution policy. So if you think this is all you need to do to protect your system from nefarious operators, now’s the time to rethink that. Execution Policy serves many good purposes, but stopping users of a computer from running commands is not one of them.
