Research on Computer Network Security Situation Awareness Platform

With the development of information and network technology, all kinds of network attacks have also brought more and more serious threats to network security, and network security problems have become increasingly serious and concerned by everyone. However, the traditional security protection technology cannot fully adapt to the current network security situation, network security situation awareness technology came into being. This paper analyzes the JDL situation awareness model and the multi-source fusion hierarchical situation awareness model in the network security situation awareness model, designs the computer network security situation awareness platform using the modularization and hierarchical method, analyzes the data processing process, software architecture and other aspects, introduces the concept of cascading, and better calculates and predicts the risk propagation path, It can provide reference for the implementation and application of network security situation awareness platform.
