摘要
EPA网关是保障EPA系统安全的关键边界设备。状态检测防火墙采取基于连接的状态检测技术,对属于同一连接的数据包只需进行状态匹配检测而无需进行复杂的规则过滤即能确定其通过与否,从而在保证数据包过滤的安全性的基础上提高了防火墙数据包过滤效率,从而改进了系统安全保障能力。
EPA gateway is the key boundary equipment for safeguard- ing EPA systems security. One staeful inspection technology which based on link is used in staeful inspection firewall, these messages which belongs to same link only need to be doing state match inspec- tion and not need to be doing complex rule filtration, we can confirm its pass or not, so we can improve the firwalls message filtration efficiency and ensure its security,so the capability of all system security safeguard is ameliorated.
