Since the terrorist attacks on September 11, 2001, computer security has taken on some new meanings. The first is positive. As part of a global tightening of belts and rolling up of sleeves, there emerged several outreaches designed to provide security training and certification to folks in all walks of life, from the consumer being alerted about identity theft, to the soldier and sailor and weapons scientists taking greater precautions with items of national security, to the common person on the street gaining a heightened awareness of hackers and crackers and cyber attackers. Gradually this new emphasis on computer and network safety has percolated down to the ordinary user’s computer in the den or living room. And because it really is a small Internet, and what affects one usually affects all, the safer individual users are, the safer the Net is for everybody.
