Tracking criminals

Ross Milburn | July 18, 2008
The computer forensics business is booming, and it's easy to see why. Ross Milburn reports that most of the evidence that convicts wrong-doers is nowadays stored in computers.

Sophisticated users

As investigative tools become more sophisticated, so do computer users. "Even only comparatively computer literate enterprise employees may use "anti-forensic" utilities (For example, Webroot Software's Window Washer) when they suspect they may be investigated," says John Bace, Gartner analyst, in a report entitled What Every IT Manager Should Know About Digital Forensics. "Strong encryption software is widely available, as is steganographic software that hides the existence of data files from investigators," adds Bace.

Chew sees a lot of cases of employees being reprimanded and fired because of abuse of IT resources. "To avoid this problem, it is important to provide internal training and education and make them aware of the threats facing the network and the company's security policies to deal with them. The key is to persuade employees to buy into the idea."
