摘　　要：随着计算机网络的迅猛发展和普及,网络安全已经愈来愈受到研究人员的重视,目前运用在防火墙上的核心技术仍然是包过滤和代理网关服务,为提高防火墙的检测效率和降低开发费用,本文从协议上入手,提出了在MAC层捕获数据包,然后在应用层过滤处理的策略,大大提高了防火墙的应用能力。As computer network developes and becomes popular rapidly,researchers have paid more and more attention to network security.Nowadays,the core technology used in firewall is still packet filtering and proxy gateway.In order to improve the efficiency and reduce the developmental expenses,the paper looks into the network protocol,and comes up with the idea of capturing packets on the MAC layer and filtering them on the application layer,in order to greatly improve the applicability of firewall.
