Industrial Automatic Control Systems and Controllers Annotation << Back A Mathematical Model for Assessing the Effectiveness of Mechanisms for Protecting Information from Virus Attacks S.V. Skryl’, A.M. Sychev, T.V. Meshcheryakova, V.I. Arutyunova, D.A. Golubkov The article presents a mathematical model for assessing the effectiveness of mechanisms for protecting information from virus attacks. The content and scenario representations of the infringer of information security in a computer system (CS) are considered in conditions when malicious programs are used as an infringing tool. A scenario presentation of the mechanisms of antivirus protection is given. The mathematical presentation of the temporal characteristics of virus attacks and information protection processes against the effects of malicious programs is substantiated. The results of mathematical modeling of virus attacks and anti-virus protection mechanisms are presented to assess the effectiveness of such mechanisms at typical values of the time characteristics of the simulated processes. The indicator of the effectiveness of mechanisms for protecting information from virus attacks as a mathematical function is investigated. Keywords: virus attacks; anti-virus protection mechanisms; infringer of information security in a computer system; effectiveness of mechanisms for protecting information from virus attacks.
