石嘴山供电局软交换系统安全实施方案

Security Scheme of Soft Switch System in Shizuishan Power Supply Bureau

针对石嘴山供电局使用软交换系统后存在网络物理结构与普通业务混用网络,以及通过连接公网实现远端用户接入等情况带来的不安全因素进行分析,制定出相应的安全防护措施。通过在中心使用双网结构,IP话机的接入在交换机上采用Voice VLAN功能,远程用户使用基于IP Sec加密技术的VPN通道等安全措施,提高了软交换系统的安全运行水平。

Based on the situation that the physical structure and normal service mixed after the application of softswitch system in Shizuishan Power Supply Bureau, this paper analyses the unsafe factors caused by connecting remote users via public network. It discusses the security measures such as the dual-network structure in the center, IP phones access the switch using Voice Vlan feature, and remote users use IP Sec based VPN channel encryption technology. After the application of safety measures, the security of softswitch system has been improved greatly.
