目前,各大企业机构已经意识到信息化对其核心竞争力的价值,纷纷建设了企业网络和各种应用系统。在完善整体网络及应用建设的同时,为了保障各种应用系统安全高效的运转,也进行了不少的网络安全建设,在互联网入口处部署防火墙、VPN、防病毒网关等网关型安全设备,防范来自外网的安全威胁；对于网络终端的安全,主要是对所有主机部署防病毒软件。但是,越来越多的变种木马、蠕虫病毒、间谍软件时刻危害着企业内网的计算机终端,而且,据权威资料统计,企业网络的安全威胁80%来自于企业内部,进行网络攻击的技术门槛越来越低(网上就可以下载到攻击工具),使得内部网络仍然面临着来自内部计算机终端的安全威胁。
At present, major enterprises and institutions have realized the value of information technology for their core competitiveness and have successively built enterprise networks and various application systems. While improving the overall network and application construction, in order to ensure the safe and efficient operation of various application systems, a great deal of network security construction has also been carried out. Gateway-based security devices such as firewalls, VPNs and anti-virus gateways are deployed at the Internet entrance to prevent From outside the network security threats; for network terminal security, mainly for all hosts deploying anti-virus software. However, more and more varieties of Trojans, worms and spyware are always endangering the intranet’s computer terminals. Moreover, according to authoritative statistics, 80% of the enterprise network security threats come from within the enterprise and the technical threshold for network attacks Getting lower and lower (online to download to attack tools), leaving the internal network still facing security threats from internal computer terminals.
