电子政务系统中网络安全方案探讨

Discussion about network security plan in E-government system

以实际应用为案例,介绍了在电子政务系统中网络安全方案的设计。在此方案中,网络硬件方案的设计上通过采用物理隔离的内外网布线方案,采用网闸和隔离网卡技术对内外网络进行物理上的隔离,通过硬件密钥方式的实现对网络信息加密;在网络软件方案的设计中,通过防火墙、VPN、网络实时信息监控等方式,实现了对数据流和网络信息在软件层面上的过滤和分析。最终,通过软硬件措施的结合,较好地满足了系统对网络安全的需要,保证电子政务系统的网络及信息安全,达到了安全性的要求。

A network security plan for E-government system was introduced in this paper. The wiring system isolated from physics layer, the network gate, the isolated network interface card and hardware encryption techniques were adopted in this hardware design plan. The firewall, VPN and real time data monitoring techniques were used in this software design plan that filtered analyzed the data stream in the network. Through the combination of the hardware and software security techniques, the security requirement of E-government system was satisfied.
