| Abstract: | With the increasing trend of militarization of space and cyberspace, China's space strategy is facing increasingly serious challenges. To secure space cybersecurity, there is an urgent need to develop a situational understanding capability for satellite cyberspace. In this paper, we first propose the key questions that need to be answered for situational understanding, construct inference rules based on satellite network situational understanding ontology and satellite network situational understanding knowledge map, propose a knowledge-based analysis method for satellite cyberspace situational understanding, and realize automatic correlation analysis of multi-source intelligence for satellite cybersecurity by reasoning on satellite cyberspace situational understanding knowledge base. Finally, the correctness and effectiveness of the proposed method are verified by case evaluation, which provides support for China's space-based asset protection auxiliary decision-making. |
