Derek Melber on MicrosoftWindows Powershell:
"If you have not heard of PowerShell you must be living under a rock. If you have heard about PowerShell, then you must have been wondering how and if PowerShell is secure. I saw PowerShell for the first time about 4 years ago at an MVP conference. With all of the effort and sweat that has gone into PowerShell, it had better come with some advanced security. Well, it does! PowerShell is not just your routine scripting language. There are built in security features, as well as some additional security you can configure once in PowerShell."
