METHOD FOR EVALUATING THE ABILITY OF A COMPUTER NETWORK NODE TO OPERATE UNDER CONDITIONS OF INFORMATION AND TECHNICAL IMPACT

摘要

FIELD: information technologies.;SUBSTANCE: invention relates to a method for evaluating the ability of a computer network node to operate under conditions of information and technical impact. To implement the method, form a simulation model of the computer network, rank all its nodes, determine weighting coefficients of each node, measure the time of opening by network computer reconnaissance, as well as the start and end time of each node and the time of the quasi-stationary state, the maximum and minimum value of the time needed for an attacker to search each node, as well as the maximum and minimum time of its recognition, the time of making a decision to open it, the time for its impact, the amount of digital information flow, the number of node connections, predict the number of opening tools available to an attacker, measure the number of damaged network nodes, record the information and technical impacts on network nodes, simulate these impacts, simulate the joint functioning of computer network models and information and technical impacts, calculate the reliability of the opening and the validity of the impact, compare them with the threshold values, reconfigure the network when it is exceeded, and make a re-commutation of the communication channels.;EFFECT: protection of computer node from information and technical impacts is improved.;1 cl, 1 dwg
