Loss Prevention Specialist
Companies hate getting ripped off, and so they hire employees to protect their assets -- both in the real world and in cyberspace. Loss prevention specialists (or agents) can work independently, or they can be hired by organizations ranging from big corporations to the FBI.
If you work for a big department store, you might consult with management on ways to prevent shoplifting -- including monitoring both employees and shoppers on foot and through surveillance videos to ensure they don't swipe any of the merchandise. At the corporate level, you'll use your skills and insight to identify potential areas for loss (including vandalism and embezzlement), and then find ways to boost security in those areas. If there are any apparent thefts or losses occurring, you'll be called upon to launch an investigation and bring the culprits to justice.
Computer-savvy former cops can put their policing skills to work online, setting up computer security systems for companies and then fighting back against cyber attacks.
