Well, it's very hard to say that someone isn't trying to bug his keyboard. It might be a valid concern. However, if someone *is* then you have to look at all the other possibilities as well. A small audio bug can be enough to pick up key clicks, and some interesting work has been done in reconstructing input based on inter-key timing. The better typist you are, the better it works. That's one small example. What about the many, many others given physical access to the environment? I'm not saying that anyone should forget about securing their computer and environment, just that if you're going to consider a new area to secure, you should think about all the other ways an attacker with such access might glean information. People with unquestioned need to secure their environment choose to create a physically secure area, rather than try to allow free access and secure individual components from tampering. It's cheaper. It's also more effective since it also prevents the placing of surveillance equipment *without* tampering with legitimate equipment, and prevents tampering with some component you haven't thought about yet. -- Darrin Chandler | Phoenix BSD Users Group [EMAIL PROTECTED] | http://bsd.phoenix.az.us/ http://www.stilyagin.com/ |
