Architecture of Modular system for Assessing Security of Telemetry Information Transmission System

This article discusses an assessment system of security level of aircraft's telemetry information transmission system. The paper analyses methods of air-ground communication systems and their security level. Analysis shows a need to build an assessment system of the overall integral index of dependability. This article contains detailed structural scheme of collection and transmission of telemetry system and scheme of protocols used in such type of communication. The security assessment system is presented as a bunch of different modules such as attack graph building module, module for simulation actions of an intruder, etc. All of them are connected to each other. As a result, the user can get recommendations on how to fix discovered software and hardware vulnerabilities as well as a list of identified weaknesses in the security policy. This allows to form an integral evaluation of the overall level of system security, as one of the basic components of the dependability as well as the level of the security of its components.
