Effectiveness Measurement of Information Network in the Condition of the Computer Virus Attack

On the basis of effectiveness model of information network and propagation model of computer virus,this paper constructs the effectiveness measurement model of information network in the condition of the computer virus attack. The blue army carries out the computer virus attack.On the other hand,the red army implements two countermeasures: 1) effective implication of antivirus measures;2) in effective implication of antivirus measures.This paper simulates the conflict of two sides,and analyzes the influence on the effectiveness of the information network.
