Abstract:

Realizing situational awareness of satellite cyberspace threats is the premise of space network security defense. Aiming at the security defense of satellite cyberspace, a series of questions that need to be answered for satellite cyberspace threat situational awareness are put forward, and the ontology of cyber situational awareness for satellite (OntoCSA4Sat) is constructed, which is used for automatic correlation and reasoning of multi-source intelligence of satellite cyberspace. Through a case of representation and reasoning experiment, the consistency of OntoCSA4Sat and the feasibility of reasoning to solve the satellite cyberspace threat situation awareness problem are verified. The case shows that OntoCSA4Sat can provide an analysis framework for satellite cyberspace threat situation awareness and support for space network security defense auxiliary decision-making.

Key words: space security, cyber security, satellite, situational awareness, ontology, knowledge base, reasoning
