Network Security Situation Awareness Model Based on Multi-Period Assessment
Chun Li, Xiao Liu Shen · Applied Mechanics and Materials · 2013
This article proposes a new model which is called hierarchical network security situation awareness model. The model emphasizes the time dimension in the assessment, it divides the assessment into two parts: short-term and long-term. The data source is the logs, flow data and others generated by equipments. These original data through the data fusion model and the situation evaluation model to obtain the short-term result, this result is the foundation of long-term. Combine the static indicators with dynamic which is calculated by short-term to figure out the long-term result. This model is based on multi-source data, and expand quantitative assessment in the different levels of time dimension, it makes up the security situation assessment in multi-period assessment and has advantage in network security situation prediction.
