电信网络安全应对策略解析

网络安全是一个涉及面广泛的问题。随着人们对网络依赖性的增强，电信网的安全性、可靠性与容灾能力越来越受到重视。虽然一开始，网络设计者就采用SDH恢复、双归属等技术来进行网络的冗余与备份。以提高电信业务的抗灾能力。但是由于灾难的不可预测性，如何做到未雨绸缪以及在紧急情况下迅速提供电信业务一直是人们关注的焦点。此外，随着WLAN、互联网和3G的广泛应用，下一代网络的安全性问题也日益受到重视。

Analysis on the Countermeasures of Telecom Network Security

Network security is a widely concerned subject. Now, people are increasingly depending on network, so they attach more and more importance to the security, reliability and disaster recovery in telecom network. At the very beginning, in order to improve the antidisaster capability of telecom service, network designers adopt such technologies as SDH recovery and dual homing to carry out network redundancy and back-up. However, disasters are unpredictable, so people always focus on how to take precautions and prompdy provide emergency telecom services. Furthermore, with wide application of WLAN, Intemet and 3G, the security of next generation network is also attracting more and more attentions.
