Approach to assessing the danger of destructive effects of malware on special-purpose automated systems

Abstract

The purpose of this study is to develop models for determining the values and severity levels of malware. The relevance of the study is confirmed by the constant increase in the number of malicious programs and the damage caused by their implementation, including on automated special-purpose systems. This paper discusses three classes of malware: malicious utilities, Trojans, viruses, and worms. Weight coefficients for malware classes are calculated using the hierarchy analysis method. An algorithm for assessing the danger of destructive effects based on the behavioral patterns of malicious programs has been developed. Pairs and triples of behavioral patterns have been identified, the joint implementation of which increases the risk of destructive effects of malware. The model was verified to assess the danger of malware implemented in various operating systems. During the verification of the model, malware has determined the hazard values and hazard levels.
