IM业务在隔离环境下代理方法的研究与实现

Research and Implementation of IM Proxy Method in Isolation Environment

网络隔离技术在承载重要信息的网络安全保障中有着广泛的应用。在对涉密内网进行物理隔离的安全隔离系统中,提出了一种能够让受隔离系统保护的内网用户使用当前主要的IM业务软件与外网进行通信的代理方法。在对MSN Messenger进行协议分析的基础上,设计并实现了一种能够在隔离环境下对MSN Messenger实施代理的软件。

Network isolation technology is widely used in protecting some networks on which important information are carried. A proxy method for some popular IM software is proposed in a security isolation system, in order to make it possible that clients in the protected LANs can communicate with other clients outside the protected LANs. MSN protocol is analyzed and a proxy for MSN Messenger in such isolation environment is designed and realized.
