Epidemiological Models Applied to Viruses in Computer Networks

Directed-Graph Epidemiological Models of Computer Viruses

Despite serious concerns raised by the proven ability of computer viruses to spread between individua.1 systems and establish themselves as a persistent infection in the computer population, there have been very few efforts t o analyze their propagation theoretically. The strong analogy between biological viruses and their co~nputntional counterparts has motivated us t o adapt the techniques of...

A modified epidemiological model for computer viruses

Since the computer viruses pose a serious problem to individual and corporative computer systems, a lot of effort has been dedicated to study how to avoid their deleterious actions, trying to create anti-virus programs acting as vaccines in personal computers or in strategic network nodes. Another way to combat viruses propagation is to establish preventive policies based on the whole operation...

Towards the Epidemiological Modeling of Computer Viruses

Epidemic dynamics of computer viruses is an emerging discipline aiming to understand the way that computer viruses spread on networks. This paper is intended to establish a series of rational epidemic models of computer viruses. First, a close inspection of some common characteristics shared by all typical computer viruses clearly reveals the flaws of previous models. Then, a generic epidemic m...

The application of DEA and queuing models to large scale computer networks

Mathematical models on computer viruses

An attempt has been made to develop mathematical models on computer viruses infecting the system under different conditions. Mathematical model 1 discusses the situation to find the probability that at any time t how many software components are infected by virus, assuming the recovery rate and proportion of un-infected population receiving infection per unit time does not change with time. Mat...
