摘要
论文针对近几年迅速发展的信息系统远程容灾技术进行数据存储结构的脆弱性分析,对目前仍在普遍采用的DAS、NAS和SAN技术以及新近发展的IP存储技术进行简单的介绍,并提出对这些数据存储技术给容灾系统带来的安全威胁的看法,分析现有的容灾技术所存在的安全隐患,提出通过层叠文件系统技术对容灾系统添加透明加密层的方案,为容灾系统的进一步开发和对已有系统的改进提供新的思路。
This paper have done a vulnerability analysis on the data storage structure of the remote disaster recovery technology based on the information system,and briefly introduced DAS,NAS and SAN technology,as well as the IP storage technology which developed quickly in recent years.This paper also pointed out security threats of disaster recovery systems brought by these technologies,and analyzed the security risks that exist in the current disaster recovery technology.Propose to add a layer of transparent cryptographic by stacking technology file system for disaster recovery system program.Finally a new ideas is provided for the further development of disaster recovery systems and the improvement of existing systems.
