摘要
防火墙是一种静态的网络安全防范措施 ,入侵检测、预防与恢复都是静态和动态相结合的技术 .防火墙的维护与防火墙的建立和配置同等重要 ,文中分析了防火墙的关键技术 ;基于路由的包过滤技术与基于特定应用的代理服务技术 ;研究了防火墙的主要维护技术 ;基于网络的入侵检测、基于管理员的预防与恢复 .
Firewall is static on guard measure for network security, Intrusion detection, Precaution and Healing are technology, which is combination of static method with dynamic method. The presented paper analyzed the key technology of firewalls: based on roating packet filtering and based on special provision appliance proxy service; This paper also discussed major maintenance tecnhology of firwalls : based on network instrusion detection and based on manager precaution and healing.
