浅析基于嵌入式网络防火墙安全策略

为了将嵌入式网络系统与既有普通网络系统进行区分,对既有网络安全系统存在的主要构成与缺陷进行了分析,探讨了嵌入式网络系统承受的主要网络攻击类型和网络防火墙安全防范的主要特点。并针对嵌入式网络防火墙的特点、防火墙的数据包过滤机理与算法进行了分析,提出采用递归流分类算法形成网络防火墙的安全策略,以达到提高防火墙数据包的处理能力。

Analysis of Embedded Network Firewall Based on Security Policy

In order to network system embedded with both ordinary network system to distinguish,this paper analyses the main existing form and defects in the existing network security system,discusses the embedded network system under main network attacking the main characteristics and the network firewall security. Meanwhile,according to the characteristics of embedded network firewall firewall packet filtering mechanism and algorithm are analyzed,the security policy put forward by recursive flow classification algorithm to form a network firewall,in order to improve the processing ability of the firewall packet.
