10 Hi,
11
12 sounds interesting (and i personally like this idea), but i think it is much
13 more easier/reliable (but also more expensive) for a company to equip their
14 employees with special pre-installed notebooks that have an encrypted
15 filesystem together with some kind of hardware-token for authentication.
16
17 The problem is, if you cannot trust the hardware you're booting the cd from,
18 then there is not much use in any well-designed security-boot-cd. Just think
19 of tampered hardware with some kind of hardware-keylogger installed (for
20 example http://www.keyghost.com/)
21
22 I think this is just one aspect why so many companies spend so much money in
23 expensive notebooks for their external workers: they have control over the
24 software _and_ the hardware.
25
26 Maybe the use of TPA-Architectures will solve this problem in the future
27 (*lol*), but i think this is completely another story :)
