Abstract: In the 5G coconstruction and sharing networks, the massive security logs and alarm audits have resulted in a lack of analysis of security data, and the disposal of security incidents is inefficient. In the face of many pain points such as lacking of threat perception ability and difficulty in security management, we propose a visualizing security situation awareness model and visualization solutions in 5G coconstruction and sharing networks. The comprehensive security situation awareness of the attack detection in the five fields of air port, operation and maintenance, system, transmission and configuration verification was tested and verified. Conduct correlation analysis of security incidents, identify crossdomain attack chain, discover the core intentions of attackers, to assist customers with achieving  active, dynamic, measurable ,visual 5G coconstruction and sharing network security, stable operation and the rapid development of the security industry.

Key words: 5G co-construction and sharing, threat analysis, security situation awareness, evidence collection and tracing, programme research, application case
