It's not encryption. It's not a password. It's not connecting through a VPN or an anonymizing service.
Security means vastly different things to a national government, an e-commerce site, or a home user.
By Bill Machrone Governments are rightly paranoid about little things like their military preparedness, new weapons systems, communications codes, and sensitive information about other governments. Businesses are constantly evolving, and your chief competitor would love to know what you're up to. On the personal level, most of us don't have anything quite so vital as state secrets to protect, but theft of numbers and information that we use every day can make our lives a living hell. You only have to talk to one victim of identity theft to understand the excruciating agony of suddenly being victimized by technology, as computers reject your bank and credit cards, and credit reports repeatedly reflect some crook's misadventures with your name and money. Security expert Bruce Schneier's new book , Secrets and Lies , details the challenges of maintaining security in a networked world.
