As the key infrastructure for the next generation mobile network, 5G confronts more complex network security threats, targeting the new architecture and techniques that 5G evolves.Also as a key component of the 5G architecture, 5GC security has become an essential research topic.5GC security situational awareness aims at understanding the current security situation and making tendency predictions in near future, which is an effective technique to counter network threats under 5G scenarios and enhance 5G operations more securely and effectively.The security situational awareness was firstly introduced, 5G particularly 5GC security demands were analyzed, then the detail design of 5GC security situational awareness system was addressed, including the system architecture and key techniques.

Key words: 5G core, 5G security operation, network security situational awareness
