A Hierarchical Network Security Risk Assessment Method Based on Vulnerability Attack Link Generated

摘要

A hierarchical network architecture is constructed in order to exactly assess the security risk of a computer network system. On this basis, a vulnerability attack link generated algorithm is proposed. And then the rationality of the hierarchical network architecture and accuracy of the network security risk assessment method are verified respectively through a typical experiment. The results of the experiment show that the vulnerabilities don't exist in isolation, the risk of hosts authorized to access can be assessed through this method and thereby providing guidance for the risk to be reduced within the system administrators' control.
