Abstract

In recent years the problem of computer security has increasingly awakened public agencies and various organizations, and sensitive data of all kinds traverse it: personal letters, credit card numbers, private data etc. The Internet has developed from a university playground to a communication network for private persons, companies, government agencies, and various organizations, and sensitive data of all kinds traverse it: personal letters, credit card numbers and bank account PINs, medical histories and examination results, management data, military secrets, and development plans of high-tech firms. Since ever more computers are networked, increasingly many computers are the targets of hackers. There are sporting hackers who want to hackers demonstrate their intelligence by intruding into others’ computer systems as well as professional hackers who target systems for destruction or to copy and sell classified information.
