IMECA ANALYSIS OF CYBERSECURITY FOR MULTI-FUNCTIONAL UAV FLEETS UNDER COMBINED ATTACKS: BASIC MODELS AND COUNTERMEASURE CHOICE

Abstract

The article explores the specifics of risk-oriented cybersecurity assessment for multi-functional fleets of unmanned aerial vehicles (UAVs) under conditions of combined cyberattacks. Basic models of sequential, parallel, and sequential-parallel combined attacks are proposed. The modified IMECA method is utilized for assessment, enabling the determination of cyberthreat and attack criticality on vulnerabilities for UAV fleet systems. Various approaches and examples of selecting and implementing countermeasures to enhance system protection against potential threats are described. Emphasis is placed on a balanced choice of countermeasures based on quality indicators (impact on risks) and the cost of implementation to ensure the security of UAV fleet systems. Further research is directed towards refining models and methodologies for security assessment under various combinations of cyberattacks and attacks by electronic warfare means.
