摘要
针对中小规模企业网(Intranet)对即时通信安全的实际需求,对企业广泛使用的MSN Messenger进行协议分析,然后基于网络嗅探(Sniffer)技术,设计并实现了一个MSN协议监控分析系统——MSNAnalyzer。该系统以监控内部网络和预防资料泄露为目的,主要针对即时通信的文字信息和文件传输。对影响系统性能的关键部分(如数据存储和数据分析)进行了分析,并给出了相应的解决方案。最后对设计的系统进行了性能测试,测试结果显示该系统具有良好的性能,系统可以在不改变现有网络配置,不影响网络运行效率的前提下,满足中小规模企业网对即时通信的安全需求。
Aims at the factual security requirements of medium and small scale enterprise network. By means of protocol analysis, detailly analyzed the application protocol of MSN Messenger. A MSN protocol monitoring system based on network sniffer was designed and implemented. Two main functions of the system are monitoring behavior of employees and preventing spilling of secret information. Also considered about issues that would affect performance of the system, such as packet storage and data analyzing. Finally, performance tests are made on the given system. The test result indicates that the system has good performance; it can satisfy network security requirements of small scale Imranet without affecting topology and efficiency of the network.
