Industrial Automatic Control Systems and Controllers Annotation << Back Expert Approach to Assessment of Level of Threat of Information Leakage on Pemin Channels and her Security from Such Threats S.V. Skryl’, S.S. Nikulin, M.V. Ponomarev, I.M. Tegentsev, M.V. Kuznetsov In article methodical approach to assessment of level of threat of information leakage on channels of collateral electromagnetic radiations and aimings and her security from threats of this sort based on systematization of interrelations between sources of threats of information leakage with her vulnerabilities and actually threats is considered. At the same time procedures of systematization are empirical, and probabilistic assessment of interrelations between sources of threats of information leakage and its vulnerabilities – expert. Is proved probabilistic representations of an indicator of level of threat of information leakage on channels of collateral electromagnetic radiations and aimings and an indicator of security of information as the events making full group. Keywords: collateral electromagnetic radiations and aiming (PEMIN); interception of informative signals of electromagnetic and electric fi elds; information leakage on PEMIN channels; the level of threat of information leakage on PEMIN channels; security of information on PEMIN channels.
