随着中国加入 WTO,外资进入中国电信领域,服务的概念将在电信行业中日见突出,而主机及应用系统的受损,将极大地影响运营商的品牌形象,从而导致客户的流失。NGN 网络涉及 IP 承载网、CN2和 DCN 网等,涉及网络安全问题。同时电信网络维护采用集中监控和管理,必须保障网络的安全运行。需要一种能够动态地适应网络变化的安全技术。入侵检测技术是当今一种非常重要的动态安全技术,与传统的静态防火墙技术共同使用,可以大幅度提高系统的安全防护水平。本文在对入侵榆测技术研究的基础上,结合电信网络的特点,详细分析了电信网络应用入侵检测系统的系统需求,设计电信网络入侵检测系统,建立入侵检测系统在 NGN 网络中的应用模型。基于电信网络的运行现状,实现电信网络入侵检测系统,对系统中的组成部分提出了设计解决方案。把电信网络入侵检测系统划分为三大模块。入侵检测系统在 NGN 网络的安全领域发挥巨大的经济和社会效益。
With China’s accession to the WTO, foreign investment into the field of China Telecom, the concept of service will be increasingly prominent in the telecommunications industry, while the host and application system damage, will greatly affect the operator’s brand image, resulting in the loss of customers. NGN network involves IP bearer network, CN2 and DCN network, etc., involving network security issues. At the same time, telecom network maintenance adopts centralized monitoring and management, and the safe operation of the network must be guaranteed. There is a need for a security technology that dynamically adapts to network changes. Intrusion detection technology is a very important dynamic security technology today. It can be used with the traditional static firewall technology to greatly improve the security level of the system. On the basis of the research on the technology of intrusion detection and the characteristics of telecommunication network, this paper analyzes the system requirements of telecommunication network intrusion detection system in detail, designs the telecommunication network intrusion detection system and establishes the application model of intrusion detection system in NGN network. Based on the operation status of telecom network, the network intrusion detection system of telecom network is realized, and the design solution is put forward for the components in the system. The telecommunications network intrusion detection system is divided into three modules. Intrusion detection system in NGN network security to play a huge economic and social benefits.
