In this paper, we propose an architecture of enforcing security services on the layer of HDFS, including Data Isolation Service, Secure IntraCloud Data Migration Service, and Secure Inter-Cloud Data Migration Service. Finally, a prototype has been implemented based on HDFS by our three custom security policies, and the time cost is given and evaluated. | ISSN:2249-5789 V Ramsundhar et al , International Journal of Computer Science & Communication Networks,Vol 3(4),307-312 Based on HDFS Safety Measures Construction Of Secret Storage Cloud Assistant Professor Rajiv Gandhi College of Engineering & Technology Pondicherry Abstract With the growth of business, an enterprise would like to make its PSC (private storage cloud) approach an infrastructure service in a Partner/Public Cloud. In such PSCs, there are some new security issues, First, how to isolate the data stored in the PSC from internal and external attackers; Second, how to make secure intracloud data migration within an enterprise, Third, how to secure inter-cloud data migration between the PSC and the Partner/Public Cloud. In this paper, we propose an architecture of enforcing security services on the layer of HDFS, including Data Isolation Service, Secure IntraCloud Data Migration Service, and Secure Inter-Cloud Data Migration Service. Finally, a prototype has been implemented based on HDFS by our three custom security policies, and the time cost is given and evaluated.

INTRODUCTION Storage Cloud is an emerging technology that leverages commodity hardware tied together to appear as a single storage device by the software, such as a cluster application, distributed file system(DFS) and grid computing[1]. HDFS (Hadoop DFS) [2] is an open source project and was designed to reliably store very large files across machines in a large cluster, and it has aroused concern from researchers and developers all over the world. Nowadays, there is growing interest for many enterprises to build a Private Storage Cloud (PSC) based on DFS like HDFS [3,4,5], which can be owned and managed internally. However, with the growth of business, an enterprise would like to make its PSC approach the infrastructure .
