Electronic communication developments have always been associated with many security risks since the ARPANET implementation in 1960s. In 1972, John Draper (Captain Crunch) unlocked the AT&T phone network marking the beginning of the modern technology of hacking. Later in the 1980s, the seminal developments in the U.S. laid the conceptual and practical foundation for future electronic crime tools such as trapdoors, trojans, and viruses. More recently in the Internet environment, electronic attacks have reached an epidemic level (US-CERT, 2004). In South Africa alone, over 500 Web sites were defaced in January 2005 and e-crime losses are estimated at around 40 billion a year.
