Abstract:
In the present article the estimation of quality information security of the information-telecommunication systems functioning in the conditions of influence threats is spent. The description of likelihood models of virus attacks to distributed elements ITCS and calculation of their risks is offered to be solved by means of discrete distribution probabilities of Markova-Poja. With the help of the count the generalized model of realization virus attack on distributed ITCS is presented. Analytical expressions for an estimation of security attacked by virus program code ITCS are received the absolute and relative indicator of security, in particular, is defined. Also the analysis of dependence of risk from change of parameters of distribution of Markova-Poja has been carried out, schedules for research of dynamics risk are constructed.
