Detriment quantitative assessment of the network security incidents

Abstract:

From the point of view on the network system availability, to evaluate the harm caused by security incidents, a performance - based quantification assessment method of network security is proposed. The meth- od references the concept of entropy in information theory to quantify the performance indexes by choosing router nodes, and compares these index changes in the entropy before and after the security incident to meas- ure the impact on the network. Worm simulation and actual provincial nodes experiment show that the pro- posed approach can be effectively applied to the quantification assessment of large-scale network availability
