The Computer Crime and Security Survey is conducted by the Computer Security Institute (CSI) with the participation of the San Francisco Federal Bureau of Investigation's (FBI) Computer Intrusion Squad. This survey indicates how often crime occurs on computer networks and how expensive these crimes can be. The 2004 survey is based on responses from 494 computer security practitioners in U.S. corporations, government agencies, financial institutions, medical institutions and universities. The most recent CSI/FBI survey is accessible, from the CSI web page, via the link below.
