| [Objective/Significance] In the face of complex and ever-changing domestic and international cybersecurity threat situations, traditional cybersecurity technologies have become difficult to detect and evaluate security conditions. Strengthening the application of threat intelligence technology and enhancing the ability of cybersecurity situation assessment has become an important link in the field of cybersecurity situation assessment. [Methods/Processes] Using network security situation assessment methods to estimate the scope and severity of the impact of hidden dangers and threats, identify network security hidden dangers and threats, and grasp the current state of network security intelligence. Applying threat intelligence to network security situation assesment, starting from three aspects: threat situation, vulnerability situation, and asset operation situation, constructs a network security situational evaluation index system. Build a hierarchical network security situation assessment method guided by network security situation assessment indicators. [Results/Conclusions] By incorporating threat intelligence capabilities, network security detection capabilities have been improved, and network security situation assessment indicators have become more objective and accurate, making it easier for network security managers to make more scientific and reasonable decisions on the overall management of network security. |
