Kerberos is security system that helps prevent people from stealing information that gets sent across the wires from one computer to another. Usually, these people are after your password. The name "Kerberos" comes from the mythological three-headed dog whose duty it was to guard the entrance to the underworld. The Kerberos security system, on the other hand, guards electronic transmissions that get sent across the Internet. It does this by scrambling the information -- encrypting it -- so that only the computer that's supposed to receive the information can unscramble it. In addition, it makes sure that your password itself never gets sent across the wire: only a scrambled "key" to your password. Kerberos is necessary because there are people who know how to tap the lines between computers and listen for your password. They do this with programs called "sniffers", and the only way to stop them would be to physically guard every inch of the Internet ... computers, cables and all. This, of course, is impossible. As long as there are physically insecure networks in the world, we'll need something like Kerberos to maintain the integrity and security of our electronic communications
