Cyber Security Systems of Highly Functional Uav Fleets for Monitoring Critical Infrastructure: Analysis of Disruptions, Attacks and Counterapproaches

The modern world is becoming increasingly dependent on the security of critical infrastructure facilities (CIF), which is monitored by UAVs, their fleets and multifunctional fleet systems (MFS UAVs). The UAV MFS have a complex digital infrastructure (DIS). The DIS is based on new information technologies that have certain security deficiencies and create new cyber threats, in particular, due to specific vulnerabilities that can be exploited externally. The provi-sion of cyber security of the CIS of the MBF of UAVs has been studied thanks to the develop-ment of a sequence of analysis of cyber threats using the IMECA procedure. An overview of existing cyber security assessment methods and their limitations was conducted; developed models of the OKI monitoring system based on the UAV MBF; analyzed cyber threats to its CIS; the criticality of cyber attacks and the impact of countermeasures; formulated recommen-dations for ensuring cyber security and general conclusions based on research results. A method of ensuring cyber security of the CIS of the MBF UAV was created, which consists of determin-ing its specific features as an object of cyber threats, analyzing violators, vulnerabilities, risks of critical violations and choosing countermeasures, the use of which allows you to increase the level of cyber security and reliability of the monitoring system and ensure a temporary response to cyber threats.
