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."

Classified Processing

[delphin42]

I used to work for a defense contractor where many of our computers were used to process classified information. Besides controlling access to the room in which the computers were located, stickers were placed over all the access points to the internals of the machine. The stickers were signed and dated by the security officer when they were placed and if one was broken, the computer had to be carefullly inspected before it would be returned to operation. Needless to say, employees were enouraged to report wear on stickers before they were completely broken, to avoid having to throughly inspect the innards of the device for bugs.
