基于iSCSI协议的远程灾备安全模型研究

本文分析了基于iSCSI协议的灾备模型的特点及其存在的安全隐患。为了解决该模型存在的安全问题，提出了基于iSCSI协议的远程灾备安全模型。其主要设计思想是在传输线路和本地存储网络以及远程灾备网络的接口处设置防火墙．用以提高两个存储网络的抗攻击能力，利用VPN来对传输的数据进行加密，从而保证数据的安全。最后通过实验验证了该模型数据传输的安全性和具有良好的抗攻击能力。

Research on Long-range Disaster Backup Security Model Based iSCSI

This paper analysis the features and the security issues of the disaster backup model based on iSCSI protocol. In order to solve the secarity problem, the iSCSI based long-range disaster backup security model is proposed in this paper. The main design idea of the model is setting firewall between the local storage network and the transmission line ,as the same way between the disaster back-up storage network and the transmission line to improve the capacity of the anti-attack of the two storage network＇. To use VPN to the transmission of encrypted data, so as to ensure the safety data. The experimental results show that the model can indeed play a role in the protection of data security by experiment.
