3G(第三代移动通信系统)系统的安全是3G系统正常运行和管理的基本保障,3G信息的安全性和网络资源使用的安全性已成为3G网络安全将面临更大挑战。文中给出入侵侵检测(IDS)技术的概念并对入侵检测系统做了描述和分析。入侵检测系统作为信息安全保障中一个重要环节,采用主动防御策略应对3G网络安全面临的威胁和存在的安全问题,最后提出基于3G入侵检测的防范和对策。
The security of 3G (third generation mobile communication system) system is the basic guarantee for the normal operation and management of 3G system. The security of 3G information and the safety of network resources have become a challenge for 3G network security. In this paper, the concept of Intrusion Detection and Detection (IDS) technology is given and the intrusion detection system is described and analyzed. As an important part of information security, intrusion detection system adopts active defense strategy to deal with the threats and security problems of 3G network security. Finally, the prevention and countermeasures based on 3G intrusion detection are proposed.
