During my career as a law enforcement officer and corporate security manager/investigator in Silicon Valley, I have investigated many types of crimes from murder to fraud and personnel issues to computer code theft. My last law enforcement position was as the Senior Criminal Investigator, on the Santa Clara County (Silicon Valley) District Attorney's Computer Crime / High Tech Theft Team where I specialized in the investigation & recovery of intellectual property, investigation of network crimes, and recovering evidence from all types of computer systems. I was on the hi tech team from 1989 to 1998 during the boom time in Silicon Valley so I had to opportunity to work with most of the major companies in Silicon Valley.

After leaving law enforcement I served in the following positions in Silicon Valley:Corporate Security Manager, Netscape Corporation
Senior Investigator at 3Com Corp (mgmt level position)
Corporate Security Manager at myCFO, Inc.
Coordinator & Instructor, Corporate Security Manager Program, University of California Santa Cruz Extension
It has been my experience that in most technology theft cases, more technology has been taken than was originally thought stolen and that the best way to recover your property and learn the extent of your loss and damage is to conduct the proper type of investigation and try to recover your property from the person who took it. This must be done quickly and quietly. Read my paper "REPORTING & PLANNING GUIDELINES - INDUSTRIAL ESPIONAGE & NETWORK INTRUSIONS" to learn these techniques. The 12 page paper is available by pressing the bullet at Planning&Reporting below, it is old but may provide some information.
There are also links to organizations and sites that security professionals and those interested in the investigation of computer crime should know such as High Technology Crime Investigation Association, ISSA, and American Society for Industrial Security.
