Abstract
Purpose: assessment of the possibility, definition of conditions and a brief description of the relational languages of logical-linguistic modeling for a formalized description and presentation of the processes of implementing information security threats in information systems. Method: application of the logical-linguistic modeling apparatus, which makes it possible to formally describe information security threats and a set of actions performed in the course of their implementation, taking into account the capabilities of relational description languages, such as Codd’s language, context-free plex-language, RX-code language, syntagmatic chains and semantic networks. Result: a brief description and comparative analysis of relational description languages and features that affect the possibility of their use for describing threats to information security and logical-linguistic modeling of their implementation processes are given. The expediency of such modeling is shown when creating promising expert systems designed for automated and automatic analysis of threats, when maintaining a data bank of threats based on the results of monitoring publications about them on the Internet. Examples of constructing formal logical-linguistic descriptions of well-known threats of computer attacks on information systems using RX-code languages and semantic networks are given, proposals are made for expanding the language of semantic networks to describe threats, taking into account new data on threats and methods for their implementation. It is noted that the proposed approach to modeling the processes of implementation of information security threats, as a rule, is applicable in the absence of the need to take into account the time factor when assessing the possibilities of their implementation.
