使用分布式防火墙技术实现内外网关数据安全交换

Using the distributed firewall technology to realize the internal and external gateway data exchange safely

防火墙是在内部网与外部网之间实施安全防范的系统,它限制外界用户对内部网络的访问,管理内部用户访问外部网络的权限,保护着主机信息在网络上的安全。分布式防火墙技术的使用可以加强内外网关之间数据交换的安全性,本文使用该技术设计、实现了内外网关数据的安全交换。

The firewall is the security system between the internal network and the external network, it restricts the outside user visit to internal network, manages the jurisdiction of the internal user to visit the exterior network, and protects the main engine information security in the network. The use of distributed firewall technology might strengthen security of the data exchange between the inside and outside gateways, this paper uses this technology to design and realize the inside and outside gateway data exchange safely.
