Found this to be an interesting article that someone might like to read as well. I did a search, but didn't see anything posted.
"Cyberwar" is a heavily loaded term, which conjures up Hollywood inspired images of hackers causing oil refineries to explode.
Some security celebrities came out very strongly against the thought of it, claiming that cyberwar was less science, and more science fiction.
Last year on May 21, the United States Cyber Command (USCYBERCOM) reported reaching initial operational capability, and news stories abound of US soldiers undergoing basic cyber training, which all point to the idea that traditional super powers are starting to explore this arena.
Recent activities with one government contractor and Anonymous, however, show clearly that cyber operations have been going on for a long while, and that the private sector has been only too ready to fill the cyber mercenary role for piles of cash.
