Cybercrime is increasing, resulting in major financial losses to businesses (Swartz, 2002). There were over 8000 computer intrusions in 1999 (Wolf, 2000), and in 2001 reported losses were estimated at approximately $455.8 million, up from $378 million in 2000. Many businesses do not quantify or report their losses, fearing bad publicity or an FBI investigation (Swartz, 2002; Wolf, 2000). Cybercrimes are divided into four categories: trespass, theft, obscenity, and violence (Wall, 1998). Cybertrespass merely involves unauthorized entry into another’s computer system. This can range from an intellectual challenge to spying and terrorism. Cybertheft, similar to traditional theft, involves anything from credit-card fraud to piracy. These two categories

are most common among juvenile hackers, whereas cyberobscenity and cyberviolence are mostly adult crimes (Demarco, 2001).
