CASE SCENARIO

ACME Industry develops custom software for the aviation industry. Its main competitors are companies like Raytheon and Boeing, as well as a few smaller contractors.

Pat Smith has worked for ACME Industry for five years. Pat’s supervisor has noted that after being passed over several times for a promotion, Pat has become quite disgruntled. The company fears that Pat may be offering proprietary company information to a competitor in exchange for a job.
