Successful business activities of a company is hard to achieve if the precondition of adequate protection of the whole information system (hardware and software), the network and data base, has not been met, i.e. if the complete information system security has not been achieved. Information outflow or damages in the IT system, i.e. situations in which information security is threatened, may cause delays in work, make communication hard, cause serious business losses, compromise the brand and image of the company, even lead to its destruction.
The response of the company and other systems to these situations in which information infrastructure is under attract must be quick and, which is the most important, ready, so as to defend them and minimize potential damage.
Intrusions of computer viruses and other harmful software can be very costly for companies, even several time more than planned by projections of financial investment in protection and prevention measures, which management, with the excuse of cutting down expenses, refuses when the security budget is made, which is a usual scenario in the regional market.
