In order to improve the effectiveness of security systems for telecommunications systems and networks, the paper considers the issue of assessing threats to their information security. The technique of definition of quantity of threats taking into account the probabilistic nature of the process of realization of negative impacts on the objects of telecommunications, the factors that promote and (or) their initiator obtained according to formal definitions of the quantitative indicators of threats. Methods of quantitative threat assessment in order to justify and describe the method for determining the threat to telecommunications networks and systems and quantifying the degree of this threat are considered by example. Recommendations are formulated for obtaining expert assessments of negative impacts on the object of Informatization and countering them with information security systems, as well as qualitative classification of threat categories for making decisions on the protection of telecommunications facilities.
Keywords:telecommunication systems and networks, information security, information security threats, security systems, methods for assessing information security threats.
