Industrial Automatic Control Systems and Controllers Annotation << Back Mathematical Models of the Temporal Characteristics of Threats of Unauthorized Access to Computer Information S.V. Skryl’, V.M. Sychev, T.V. Meshcheryakova, Yu.S. Nikitina, V.V. Gayfulin, A.A. Suvorov The article deals with the method of transition from the functional representation of the actions of the violator of information security in the process of implementation of threats of unauthorized access (NSD) to information in computer systems (CS) to the mathematical one. Restrictions on mathematical representation of temporal characteristics of such threats as random variables are substantiated. The structure of mathematical models of these characteristics is given. Keywords: computer systems; unauthorized access to computer information; time characteristics of threats of NSD; mathematical models of threats of unauthorized access to information in computer systems.
