Security Tools for OS X -- DenyThumbDrives

The other day I posted about a problem regarding the default behavior under OS X, which ignores permissions for mounted firewire drives. I decided to look for a solution to this rather than relying on administrators to set the proper option. What I uncovered is a nifty tool called DenyThumbDrives that allows you to prevent the mounting of local volumes based on their size and media type.

This tool allows me to solve the issue with insecure default settings for firewire disks while also allowing me to prevent data theft via USB thumbdrives and external disks. I understand data can still be stolen via other means such as network connections; however, it's a step in the right direction. DenyThumbDrives is also a free utility.
