Schneier On Un-Authentication 336
Trailrunner7 writes "Bruce Schenier writes on Threatpost.com: 'In computer security, a lot of effort is spent on the authentication problem. Whether it is passwords, secure tokens, secret questions, image mnemonics, or something else, engineers are continually coming up with more complicated — and hopefully more secure — ways for you to prove you are who you say you are over the Internet. This is important stuff, as anyone with an online bank account or remote corporate network knows. But a lot less thought and work have gone into the other end of the problem: how do you tell the system on the other end of the line that you are no longer there? How do you un-authenticate yourself? My home computer requires me to log out or turn my computer off when I want to un-authenticate. This works for me because I know enough to do it, but lots of people just leave their computer on and running when they walk away. As a result, many office computers are left logged in when people go to lunch, or when they go home for the night. This, obviously, is a security vulnerability.'"
Effective way to keep screens locked (Score:5, Funny)
A bank I did some consulting work for had a very effective cultural rule to force people to lock their machines when they left their desks: if you find an unlocked machine, pull up the email client and send a message to everyone: "today's my birthday, drinks on me after work!" (other NSFW messages left to the readers imagination.)
Apparently, very few people left their machines unlocked more than once...

Of course, the fun rose exponentially when two people had their machines unlocked. I would frequently carry on a whole phantom conversation.
"Hey, let's go to lunch tomorrow"
"I can't, I have to wax my hamster"
"I didn't know you had a hamster"

MS solved this problem, but removed it with W2K+ (Score:5, Funny)
Windows 95/98/ME had a built-in solution to this problem, but MS removed it in the Win 2K and newer. They simply had the machine crash every 2 hours. Heavy handed, sure, but it worked.

Well, at least you aren't 17 anymore. 1 out of 2 isn't bad.

Any time someone left a machine unlocked in the MC we would pounce on it. It would take less than 2 minutes to get emails out to the appropriate members of the chain of command to volunteer the Marine for every shit duty we could find (and swap his or her desktop background screen saver to something highly entertaining or inappropriate).
