Abstract:

For making more scientific and comprehensive quantitative measure on the security of the LAN, the idea of measuring the defense performance byusing attack effect is proposed. The malicious code, network attacks, information sabotage attack, information attack, and other content security attack scenarios are designed. Attack target set containing attack duration, control duration, interference duration, infection rates are proposed.  Based on the attack target set, a network defense performance model using AHP analysis method is presented. Simulation results show that the proposed measurement method and model can better measure the security of network protection systems.

Key words: security measurement;LAN;index system;quantitative calculation
