A recent survey asked IT employees that question. The result: 88% would take sensitive company information with them on the way out, according to the polls by security solutions provider Cyber-Ark.

The most targeted types of information are passwords, financial reports, customer databases and R & D plans.

Passwords rank as the most coveted piece of information. A third of the devious staffers said they’d take password lists out the door with them. If unchanged, those passwords could give ex-employees access to any information in the company’s network.

Cyber-Ark’s advice: Change passwords routinely and have IT departments give access rights only to the employees who need them.
