Educause is sponsoring a contest for Computer Security Awareness- I just happened to hear about this and there looks like about a month to pursue if you know of a student or other group interested in.

A total of $8,800 will be awarded:

four "gold" prizes of $1,000, four "silver" prizes of $800 and four
"bronze" prizes of $400.  The contest is now open and has a deadline of
April 30, 2009.
