Characteristics of Network Non-optimum and Extensionality Security Mode

Traditional security models and single security technology cannot keep up with the change of complicated network structure and varied intrusion measure. Network security manage based on optimization has traits of low manage cost, high agility, wide applicability. This paper introduces network security management based on non-optimum system theory into new network security model, and emphases on its structure, control strategy and implementation. This paper has also come at sub-optimum principle of the networks system optimization, established the conception of sub-optimum thresholds and put forward three theorems about non-optimum parameters. Finally, according to the previous practice of optimization, kind of method has been developed to approach the sub-optimum optimum from non-optimum.
