The command-line program to modify user permissions for files in Windows is called icacls, where ACL is for access control list, and i'm guessing the S indicates plural. What does IC stand for?

I had thought CACLS was "Change Access Control ListS", but Wikipedia's article on Cacls: section on icalcs says "Integrity Control Access Control List".

What can I say, except "Trust the 'pedia"?

I think it stands for Inherited Change Access Control List System (or Security or maybe Service?), though it's anyone's guess since MS seems to have buried that little tidbit of information deep in the bowels of technet.

It's essentially just a new and improved iteration of CACLS that was introduced with Windows Vista.
