Faronics has released Deep Freeze Mac OS X 1.7, the latest version of its flagship workstation security software. Deep Freeze Mac OS X provides two types of protection: Non-restrictive protection allows a standard user to make any changes they like in their home directory, but restores the entire directory to its exact original configuration at a specified tim; Restrictive protection lets an administrator specify read, write, and execute privileges on-the-fly on a per-user basis for any file, folder, application, or system preference pane, no matter where it resides on the hard drive. Deep Freeze Mac OS X requires Mac OS X 10.2 or later. Various pricing options are available from the Web site.
