Germany’s ‘revenge rockets’ were uncovered by spies who seemed to be so unimportant they weren’t noticed.

Every company who works with classified information needs a written, shared and used elicitation countermeasures program.

If you have a security clearance, it doesn’t mean you can’t relax and enjoy your vacation. You must remember, however, you have a clearance.

Security clearance holders are briefed regularly on security protocols and standard operating procedures. Unusual circumstances still occur, and we need to be prepared for those, as well.

A wise mentor of mine once advised, “There are two ways to guarantee you’ll lose your clearance: Fool around with money and morals.” 

All cleared facilities have implemented programs to spot insider threats. Do cleared employees also know how to report suspicious behavior and potential leaks?

Security professionals dissect bombings as one would a corpse after a mysterious killing. They offer lessons learned and advice to follow.

Always remember to err on the side of caution. If you interact with someone whose identity you don’t know, report it. If you find yourself wondering, always report.

One successful feature of espionage is simply to take what’s lying around. What items are you throwing in the trash?

Do you know what happens to the documents you create? You may be leaving a paper trail that puts your company or agency data in jeopardy.
