Model of complex flows address threats to information security in communication networks special purpose

Currently, special-purpose communications networks are widely used in government bodies, bodies that carry out the functions of the country's defense, state security and law enforcement. In connection with the features of the functioning of infocommunication systems and communication networks for special purposes, it must be borne in mind that they are deployed and provide management and interaction within the existing departmental and interdepartmental communication systems. The article proposes a model for the formation of a set of means to counter threats to information security in communication networks for special purposes. A description of such complexes is given, situations and grounds for their application are considered. Attention is drawn to the identification of common technological features of the formation of a set of means to counter threats to information security in communication networks for special purposes. To formulate requirements for complexes of means of counteracting threats to information security in communication networks for special purposes, a rule base has been compiled on the basis of which certain countermeasures will be selected. The authors modeled the functioning of a complex of countermeasures using the apparatus of linguistic variables and fuzzy expert systems. Based on the results obtained, requirements can be proposed for creating a set of means to counter threats to information security in special communication networks. The mathematical apparatus used in this article, based on the use of linguistic variables and fuzzy expert systems, can fully characterize the dependence of the effectiveness of countermeasures on the totality of implemented protective measures.
