Information Network Security Situation Awareness Method Basedon Heterogeneous Data Sources
Perceiving the security situation of information networks provides a reliable basis for proposing and implementing secu-rity protection strategies,greatly avoiding information loss and leakage.In this context,a method for information network security situ-ational awareness based on heterogeneous data sources is studied.Utilize integrated models to collect heterogeneous source data and implement cleaning processing.Extract network security situational elements from heterogeneous source data using principal compo-nent analysis.Calculate the quantification value of primary elements based on the weight of secondary elements in the network security situation.Input it into a deep neural network,calculate the security situation value of the information network,and classify the securi-ty level.The results show that the security situation value of a certain company shows a trend of first stabilizing,then decreasing,and then increasing.The network security level starts to decline after maintaining a very high level for a period of time,until reaching a lower level,and then rebounds to a very high level.
