Disable or detect wireless network, bluetooth and 3G cards...
Posted on 2009-05-12
During this year's exams students here are allowed to use their own computers when writing. They are also allowed to store any information relevant to the subject on their drives. However any form of communication (between computers and from outside sources) is strictly prohibited.
Relevant modes of illegal communications might be:
Internal 3G mobile cards
IrDA (low risk)
I have tried to find out if Windows has a 'soft spot' common for the above networking modes, which could easily be disabled programmatically. However this does not seem to be possible. (If anyone here has other information, please pop in). The second best solution would be to have a small applet running monitioring any network activity. Once network activity is discovered, a colored alert window pops up on top of the current window, attraction the attention of the exam surveillance staff. It would be relatively easy to have all students manually deactivate their wireless and bluetooth cards and have the above applet monitor if they get activated again.
I'm interested in tips on how to avoid any non-cable communication occur to/from a computer in this situation. The small monitoring applet mentioned above should display a small stamp-size window in the lower right corner of the screen when running (to proof it is actually running), and an attention-attraction colored window when an illegal situation is detected. The visual part is no problem, but I need help and tips on how to properly monitor or detect the above mentioned communication modes on Windows XP and Vista.
Thanks a lot for creative comments and tips on this topic.
