Industrial Automatic Control Systems and Controllers Annotation << Back Characteristics of Probabilistic Timeliness to Threats of Information Security in Computer Systems for Different Violation Models A.M. Sychev, T.V. Meshcheryakova, K.S. Skryl’, Yu. S. Nikitina In an article, there are the conditions of timeliness to threats of information security in computer systems for standard violation models: simplest model, combinational models and model of integral action of threats. The stated conditions are considered as the accidental events. The probability representation of such accidental events is provided by the changing of timing parameters of threats to information security and response mechanisms to these threats. There is a graphic interpretation of such representation in the article. In addition, there is a general form of indexes of timeliness to threats of information security in computer systems for standard violation models and the formal representation of these indexes as probabilities that belong to the areas of timing parameters changing of threats to information security and response mechanisms to these threats. The private type of this representation is provided. Keywords: violation models of information security in computer systems, conditions of timeliness to threats of information security, an index of timeliness to threats of information security.
