Hierarchical Cluster Analysis of Network Security

Network security covers a wide range, mainly to ensure the integrity and effectiveness of network theory and network technology information, fully grasp the security state of the entire network system, has become an urgent need for managers and decision makers. This paper constructs an evaluation index system composed of “physical and environmental security, network and communication security, software and data security, network security precautions, personnel and management security, network security training”. In this paper, a hierarchical cluster analysis model is constructed, which is composed of “constructing initial sample matrix, sample matrix data standardization, deviation square and clustering strategy”, and its scientificity is verified by experiments. The experimental data of 24 representative network systems were selected, and the experimental results were analyzed by means of case processing summary, clustering process, icicle chart and clustering pedigree. The results show that the mathematical model proposed in this paper can scientifically classify network systems and provide basic support for network security management.
