A Quantification Method for Network Security Situational Awareness
Lin Yuan · 2010
After analyzing and quantifying the network security situation awareness, a quantification method for NSSA based on conditional random fields (CRFs) was proposed. Based on the positive and negative ideal comparative standards, the evaluation index elements are processed in a non-dimensional grey way, and a qualitative-quantitative evaluation method with the multilayer linear weight for the network security situation awareness is put forward. Finally, the feasibility and validity of the method are verified by analyzing some practical examples.
