Abstract
The distribution of information technology is a step forward in accelerating rapidity and efficiency of transferring information. As each system, that is subjected on different anomalies, so that computer information systems are also subjected to different disorders to make a stop or destruction of it. There is a question: who would like to do harm to the system which is produced for people and society needs? HUMAN BEING is the response. However, it is not every human being, but a person, popularly called a hacker, who is educated in the information technology field and who makes damage, using computers and the Internet. Hacking and hacktivism as a function of information systems and technologies, expressed as a pattern of ethical or unethical hacking, represent a global menace, for some people, as well as whole institutions and arrangements. The actual problem, imposing here, is how creators and users of computer information systems can find a solution, or compatible protection and preventive acting in those areas where such a problem appears.
