基于Linux防火墙与入侵检测系统的FIBDS模型

The Model of FIBDS Based on Linux Firewall and IDS System

防火墙是内部网络用来防止来自外部网络侵害的一种安全防范工具.入侵检测系统则用来对外部网络的非法入侵进行监督和报警.将防火墙和入侵检测软件的优势结合起来,提出一种基于防火墙和入侵检测系统的FBIDS模型,并给出了模型实现的关键技术.

Firewall is a network component applied to protect the intrusion of outer network in the intranet. Intrusion detective system is used to monitor and warn the illegal intrusion. The author combines the advantage of firewall with intrusion detective software and proposes a FBIDS model based on the cooperative work of firewall and intrusion protective software as well as the key technique for its realization.
