You know you're a computer security professional when:

You not only lock your laptop with a physical cable leash, but you change the combination of the lock when it's not in use so that it can't be "compromised".

Although you have no ill intent, you spend no small amount of your downtime in airports thinking of ways to circumvent TSA security -- and you've come up with several can't-miss terrorist ideas that even Jack Bauer couldn't stop.

You lock your screensaver with twice as much insistence when security friends are around than when strangers are, because you're not nearly as worried about a stranger's intentions.

You're immediately discontent with all newly announced security solutions, even before you know anything beyond the name.

Having extralong passwords that you must type over and over again to get correct is not a bother.

You have a database program to store all your passwords, but even it doesn't contain a single, decoded password.

When you read industry-mandated security guidelines, you chuckle at all the newbie mistakes.

You secretly hope you don't miss a big virus outbreak while you are out on vacation.

Any security book you read is covered in pen from the technical corrections you've made.

Very true.
