Dedicated Information Network Security Defense System Research And Design,

The development of information technology has permeated every aspect of society, the army is no exception. Along with the computer technology, the development of information technology, the information network system will become the key military various business platform. Meanwhile, information network security defense system more and more cause for concern. At present, our military's information network construction has already formed a certain scale. But compared with the rapid development of army's information technology, security and defense system is relatively lag and weak . Construction of a network security defense system, building an effective network security system has become an increasingly pressing issue .This paper analyzes the security of military information network construction of the basic status, weaknesses and threats facing the reality, and then combined with the military unit of the actual construction of integrated information network, its current situation, the security requirements analysis, security and defense system for the functional design, and then for The Network developed a set of security and defense programs, and determine the relevant technical measures and product selection. Among them, the first focus is network traffic monitoring and intrusion detection, the establishment of a traffic anomaly detection model adaptive AR; The subsystem carries on analysis on the security situation and the security requirements firstly, then designes based on Policy (Security Policy), Protection (protective), Detection (detection), Response (response). Finally carries on the test to the security subsystem, has made the good progress. That all had achieved good results. Technology used in the text are advanced and mature in the world, has a good open and operational, the entire design can be used as security requirements similar to the reference model solution.Therefore, in order to strengthen shielding systems construction of the information security and to sharpen whole protection capability of the information security system, the deep research on synthesis safety protection questions of the information network has the vital practical significance embarking from the system theory viewpoint.
