Research On Telecom Network Security Technologies

Today with the popularization of the computer networks, network security has been becoming a day by day prominent problem. Hacker's invasion and attack is extremely prominent, the skill of Hacker is more and more wise. At the same time, the computer virus carry on the widespread dissemination with the aid of network, often causes very big harm with economic loss. Therefore, based on the safe obtained from the foundation computer network, how to enhance the information security of the enterprises IT systems, has become a hot topic. The method how to enhanc the security level of enterprise computer network by using network security technology, is presented in this paper, which includs several security technology as follow:Invasion examination technology: The invasion examination system collects each kind of information which will be analysised by the expert system to discover the latent attack behavior of networks. The network invasion examination system(NIDS) catches and analysis all texts of a telegram in network, discovers attack attempt, according to the strategy which beforehand formulates informs the manager or takes the protective measures voluntarily.Safe scanning technology: The safe scanning technology is mainly uses for to appraise the computer network system the security performance,it is an important technology of network security defense, its principle is uses the simulated strike to inspect the known security loophole which possibly exists item by item.
