SatAF-EE:An effectiveness evaluation algorithm on attack flow of satellite network

With the rapid development of satellite networks, ensuring the security of satellite networks has emerged as a pressing concern. In light of the characteristics exhibited by satellite network cyber attacks, the structured construction method of workflow is applied to the description of such attack behavior, and the concept of “satellite network attack flow” is proposed. Based on this, an effectiveness evaluation model for satellite network attack flows is established by integrating the space attack research & tactic analysis matrix with the analytic hierarchy process and grey system theory. The proposed method can quantitatively evaluate the effectiveness of satellite network attack flows (i.e., satellite network attack effectiveness) and analyze the satellite network security situation from the attacker’s perspective. Due to security concerns, satellite network attack experiments may affect the actual operation of satellite networks and even trigger security incidents; thus, three representative satellite network attack events are comprehensively evaluated to verify the practicality and efficiency of the proposed method.
