Intrusion Detection For Your PC Case

Anonymous Coward writes "Ryan du Bois, from genbukan security (aka red0x), has created a chassis intrusion detection system for your computer box: the actual physical case. He also wrote a paper describing three separate implementations of this CIDS system: Contacts, Pressure switchs, and a PLA (programmable microchip). Included in his paper are complete designs for the first two and a promise for the last to come soon. Definitely worth a read. The paper is available in many formats including OpenOffice 1.0, HTML , TEXT and a Tarball of them all. You can also obtain the signatures as well as his Automated Security Tools Project, of which this is a member."

what I learned from the movies

is that we need lasers set up in an inefficient pattern surrounding the box itself.

'hackers' chastity belt

[paradesign]

this seems kinda funny. First 'hacker' makes case mods so you can see al of his frilly internals. then he puts on a system so you cannot touch or have access to them. this is strangely reminiscent of the lingerie / chastity belt scenerio, see... no touch. see... no touch.

Back in the sixties, rumor has it that men tended to view their motobikes as something of a sexual nature, perhaps equating it with a woman.

They cared for it, they made it beautiful, they rode it, they rode it, they rode it...

This comment on chastity belts brings back to light the much debated issue of the hacker's liaison with his computer. He cares for it, makes it beautiful (case mods), sometimes prefers it naked (no case), install the latest software (XP) and then it crashes and he gets screwed, screwed, screwed...

I guess if they had porn on bikes we'd never had gotten this far.

My IDS...

Gracie, the gray tabby cat sleeps atop my PC case. If her bed is disturbed... and I do mean in any way... she cries for days on end. She can't be consoled. I have no choice but to hunt down the man what tried to jack my HDD and present his head to the cat like she does when she brings me mice.

Great intrusion detection

[wowbagger]

Leave a fake grenade, with the pin pulled and the spoon held down by the outside of the case in the computer.

Identify intrusion by the stain on the floor.

For bonus points, replace the fake grenade with a real one.

Don't worry, Microsoft already takes care of this.

[Anonymous Coward]

Don't worry about it if you have Windows XP.

1) If someone breaks in and doesn't change anything inside, you don't care.

2) If someone DOES break in and change anything in the hardware configuration, Windows XP will think it is no longer running on the same computer and stop working until you contact Microsoft for a new activation key.

Dear Slashdot, wot's a microswitch?

[Anonymous Coward]

I have never seen a microswitch. Perhaps one of you could send me a photo of one.

Actually, whenever I need a microswitch (home-made XYZ plotters, etc), I open up a case at work and pinch the 'CIDS' device. Very handy!

"Sounds interesting, but incredibly impractical."

Ah! You have issued the rallying cry of the /. case-modder...

"It sounds interesting yet totally impractical! To arms, my brothers! Let us mod this case!"

A-Bombs have existed for quite some time, but if someone cobbled together a DIY nuke, it would sure be news.

I wouldn't recommend using one as a way to tamperproof your PC though. The radiation causes parity errors.

If you want to see real CIDS, go talk to people who make and use military encryption devices. (shake some of them too hard and they electrically self-destruct -- they erase their tiny little brain.)

And some devices erase the tiny little brain of the intruder as well.
