As a security investigator, you have been asked to determine if company confidential information (intellectual property) has been copied from enterprise computers. Investigation centers on a particular computer that has shown a high volume of network traffic at unusual times. In the course of conducting your investigation you discover that large capacity removable media has been attached to the suspect computer. A preview examination reveals that software used for secure deletion had been downloaded to the desktop. Prepare an investigative plan listing the lines of investigation that you plan to pursue.
