一种Intranet信息保护系统的设计和实现

鉴于当前单位信息安全和知识产权所面临的威胁和挑战、网络上恶意移动代码攻击事件日渐增多及破坏力度增大的事实,着重研究Intranet信息保护技术。提出了一种Intranet信息保护系统的体系结构,所实现的系统包括数据采集、数据预处理、策略管理、数据分析、数据表示五个部分。将潜在语义索引方法运用到该系统中,很好地实现了分析效率和准确度的平衡。系统可以检测和拦截不允许传送的信息内容,有效阻止恶意移动代码,为Intranet信息安全提供了一种行之有效的解决方案。

Design and Implementation of an Intranet Information Protection System

With the widespread use of the Internet and Intranet,it is becoming more and more important for us to pro-tect privacy information and intellectual property right of corporations and stop malicious mobile code.This paper focuses our thoughts on information protection technology and presents an architecture for Intranet information protection system(IIPS).The system includes five components that are data collection,data pre-process,policy management ,data analysis and data presentation.Latent Semantic Indexing(LSI )is used in IIPS to analyze the information flowing between Intranet and public networks.Experimental results show that the system carries out the analysis accurately as well as efficiently.The system detects and stops malicious mobile code and information which is not permitted to be transmitted.It pro-vides an effective solution to information protection in an Intranet environment.
