If all you have is a hammer, all problems look like nails.

If you go to a locksmith-solution space looks like locks, a contract guard company-solutions look like guards; same for intrusion detection-all solutions looks like IDS.

Cyber security solutions are applicable to physical security. Physical security concepts are applicable to cyber security. 

LEARN about as many aspects of security as you can...and then cross functionally creatively apply them!

EVERYTHING has security implications and lessons that can be applied to your job. BE CREATIVE. :) But don't annoy your boss!

No one counter measure is sufficient or appropriate...even James Bond's exploding Lotus theft prevention system in For Your Eyes Only.

I had a test for guards their for education and fun. 

Imagine the CEO comes to you and asks that you "secure that desk" and points his desk. How many ways can you think of complying with his order?

Most said "Put a lock on the drawers." Few went beyond that.

A few added: "Place a guard at the office door."

I had 55 solutions to his request BUT much better to ask "What exactly am I securing? What loss do you want to prevent?" This significantly narrows your choices.

Is it the Resolute Desk?, is it the bottle of Glenlivet in the desk?, is it the confidential merger information?, the picture of his mistress?, his cocaine stash?, his 357 magnum???
ASK!!!
