A few years back, I attended a workshop hosted by NJ Infragard. It's a group that puts on workshops related to security, specifically computer security.
(Amusingly enough, every time I mention Infragard, I get an email from someone telling me how "bad" they are. I also get a comment every time I post anything remotely related to Web design, from someone who hates a stock photo company called Getty Images. Always interesting to see what brings out the commenters and emailers!)
Anyway, that said, one meeting had the key speaker being Kevin Murray, of Murray Associates. His company is one that is part of an industry I didn't even realize exists. His company will come in and sweep your company for wiretaps, listening devices, and the like. It was quite educational for me. He told some crazy stories about how far people go to spy, in politics, and in private industries like pharmaceuticals.
Anyway, the company maintains a blog with tons of news involving espionage, privacy, and security. This site is definitely one I check out from time to time. I enjoy computer security, but I am not actively involved in it on a day-to-day basis. Reading the perspective of someone who is out there in the field is entertaining and educational for me.
