The research on dynamic self-adaptive network security model based on mobile agent

The rapid development and wide application of computer networks presents a new challenge to information security and network security. Traditional security models and single security technology cannot keep up with the change of complicated network structure and varied intrusion measures. Network security management based on policy has traits of low management cost, high agility and wide applicability. The mobile agent not only collects but also processes data, overcomes traditional agent's shortcomings, improves response and relieves network burden. This paper introduces network security management based on policy and a mobile agent into a new network security framework, and emphases its structure, control strategy and implementation.
