Network security defensive system, method and security management server

Abstract

The utility model relates to a data communication network safety technology, more particularly, provides a network security defense system and the method as well as a safety management server, so as to conduct the active defense against the terminal equipment which attacks the severs in the network. The network security defense system comprises a safety certification client, a safety access exchanger, a certification charging server, a network attack monitoring unit and a safety management server. The network security defense mechanism provided can ascertain the terminal equipment which attacks the network and assume the active defense against such terminal equipment, so as to effectively guard against the continuous diffuseness of network attach incident.

Description

technical field

[0001] The invention relates to data communication network security technology, in particular to a network security defense technology. Background technique

[0002] With the continuous advancement of network technology, network intrusion activities are also developing and becoming increasingly active. Among all kinds of network intrusion activities, network attacks against servers, especially key servers, can be said to be the most threatening and likely to cause the greatest loss. A key server refers to a server that stores important information in the network. A large amount of important information is stored on a key server as an intangible asset. Once it is threatened by network security, it will inevitably affect the stored important information, resulting in immeasurable losses. What's more deadly is that these network intrusions come not only from external hackers, but also from insiders.

[0003] At present, various enterprises and units mainly ado...
