Recently there was a situation where a student at Dawson College in Montreal hacked into his school’s network and was expelled from the school.
What seemed like a pretty obvious and reasonable result turned out not to be so clear-cut.
Eric Chabrow wrote a column on this at govinfosecurity.com, The Ethics Behind Gray-Hat Hacking.
He asked me for my opinion, I provided some background on an incident that happened while I was the CIO at the US Department of Transportation which I felt provided some insight into the question at hand.
