O divine art of subtlety and secrecy!
Through you we learn to be invisible, through you inaudible;
and hence hold the enemy's fate in our hands.

-- Sun Tzu, The Art of War, c. 500bc

Security is a process and not a product, and should be treated as such. I think General Patton said it best when he said:

“Fixed fortifications are monuments to man’s stupidity.”
