[QUOTE="509322, post: 623604"] 1. Block *.ps1 and other script types by default in User Space 2. Run powershell.exe with restricted privileges 3. Scripts will inherit restricted privileges from restricted interpreters - [I]even in System Space[/I] 4. Block the loading of *.dlls from User Space 5. Block the launch of *.exe from User Space 6. Disable macros 7. Whitelist only scripts that have been audited 8. If you want to get crazy you can audit scripts, sign them, and play with powershell language modes, and set restrictive policies PowerShell can be run from a *.dll or *.exe, even if powershell.exe and powershell_ise.exe are disabled. PowerShell can be launched via macros\scripts. PowerShell should not be shipped with\enabled by default on Home versions of Windows - that's just my personal opinion. [/QUOTE]
