An Evaluation Model of Computer Network Security Based on Rough Set

It is very important to know the security status of computer networks accurately.At present,most computer network security evaluation system don't analyze the datum thoroughly.Therefore it is difficult to acquire the security status of computer networks at the whole.An algorithm model with rough set theory to mine the rules of computer network security evaluation is proposed.A rough set knowledge system description of computer network security evaluation is studied.A fuzzy rough set attribute reduction method is given.The decision rules mining method presented in this paper is validated with a simplified network security evaluation data set.The experiment results show that decision rules acquired by the method are in accord with the fact.
