Network Security Assessment Detection Method

With the rapid development of information computerizing for the police network, all kinds of confidential information exist in it. With police network security technique, the method to deal with network attack is to adopt passive defense means. All these means seem too less able to handle swiftly changing attack methods. In order to protect the police network system proactively and to make the police network security defense system dynamic and change the measure actively but not passively are the task of network security research.The paper aims at further research on the system of testing and evaluating network security. The research work mentioned in this paper is mainly about:(1) It analyzes the problems and solutions of network security generally. It presents the basic requirements, problems and techniques of network security.(2) It presents the key techniques of this testing and evaluating system, which includes the testing of vulnerability and the evaluating of the tested system. It describes the techniques of scanning holes and simulating attacks, which are used to find the vulnerability of the tested system; it provides one way to evaluate the risk level of the tested system.(3) It describes the check and measure and implementation of this system, which comprises the aim of check and measure, the architecture of this system, the modules of the system and some other techniques in the implement. It presents the results of check model of this system, which indicates that the design and implementation of this system are feasible.
