The Design And Implementation Of Security Assessment In Network Security Management System

With the development of network technology, network security issues will influence the socio-economic development and an important factor innational development strategies. In the face of the increasingly complex structure andlarge size, especially the use of a variety of new security vulnerabilities in a large number of attacks by an intruder, information system security risks and threats facing the increasingly serious. As the diversity of the computer network has connected, interconnected, open, and so on, making the network is vulnerable to various attacks,network security has become the network construction of a very important aspect. The best network security situation is "what security incident did not happen", but in the actual network environment, the existence of the vulnerability of the network system itself, even if the vulnerability itself does not cause direct damage to the network system, once these vulnerabilities are Bad behavior of the attacker has exploited will inevitably bring great risks to the network, so the safety of the network becomes very important to accurately assess.This paper proposes a comprehensive qualitative plus quantitative method of safety assessment, the assessment involved collecting various types of security incidents,presented various types of network security incidents by security level and to developthe relevant level. Design and implement network security event management systemintegration based on risk level storage modules. Implemented based on the assessment of network security systems business, and gives the security assessment to achieve results and trends.
