Modeling Information Security Threats and Determination of Their Relevance for Information Systems of Informatization Objects of Federal Executive Authorities
( Pp. 106-114)

Task. The purpose of writing this article is to improve the security of information in information systems. Model. The article explores methods for modeling information security threats and determining their relevance for information systems of informatization objects of federal executive authorities. Conclusions. The study is based on an assessment method that uses a cluster of outcomes, and the concept of “significance coefficient” is also introduced, as the product of the corresponding values of the priority vectors of outcome clusters. Value. The materials presented in the article will help improve methods for analyzing and evaluating the assets of an informatization object, vulnerabilities, information security threats, possible attacks and security goals.
