During the communication between various computer system parts under a basic unit various threats can appear causing different damages into the system. The spreading of the computer virus into the system must be investigated under modeling analysis and simulations must be applied. In this work survival analysis models have been introduced to overcome the problem with the computer virus. During that process of spreading two main considerations analyzed: (1) the epidemiological models of the spreading and (2) the survival of the computer virus inside the system under mathematical modeling.
Keywords: computer security; computer virus; malicious software; survival analysis.
