Marcos K. Aguilera, Minwen Ji, Mark Lillibridge, John MacCormick, Erwin Oertli, David G. Andersen, Mike Burrows, Timothy Mann, Chandramohan A. Thekkath
2018
We propose a practical and efficient method for adding security to network-attached disks (NADs).  ...  In contrast to previous work, our design requires no changes to the data layout on disk, minimal changes to existing NADs, and only small changes to the standard protocol for accessing remote block-based  ...  Acknowledgments We would like to thank Fay Chang and John Wilkes for useful discussions as well as our shepherd Greg Ganger and the anonymous referees for helpful suggestions.  ...

Performance Analysis of RAIDs in Storage Area Network

Sneha M.
2015 International Journal of Computer Applications  
Storage area network is a disk system concentrated on network which allows clients or servers to use the disk system as a local disk.  ...  Direct Attached Storage, Network Attached Storage and Storage Area Network are the different kind of networking and storage facilities used in different domains from small scale industries to large scale  ...  The replication done at the block level is done over TCP/IP protocol which is secured by the SSH established on the network.  ...

NAS: A DISTINCT WAY TO STORE AFFORDABLY

Joy Singh, Sudhanshu Kumar Jha
2020 International Journal of Engineering Applied Sciences and Technology  
Network based storage combined with smart storage management like DAS (Directly Attached Storage), NAS (Network Attached server), and SAN (Storage Attached Network).  ...  The requirement for large storage repositories has increased multi times in recent times; new type of network storage has become important for large data storage.  ...  SCSI is a "block level" protocol, or block-I/O, because SCSI commands specify particular blocks (sectors) on a specific disk. Initially, SCSI commands were sent through "parallel SCSI" only.  ...

Design, implementation and evaluation of security in iSCSI-based network storage systems

Shiva Chaitanya, Kevin Butler, Anand Sivasubramaniam, Patrick McDaniel, Murali Vilayannur
2006 Proceedings of the second ACM workshop on Storage security and survivability - StorageSS '06  
This paper studies the performance and security aspects of the iSCSI protocol in a network storage based system.  ...  Our proposed lazy approaches improved throughput by as much as 46% for microbenchmarks and 30% for application benchmarks in comparison to the IPSec based approaches.  ...  The work by Aguilera et al [4] addresses the access control mechanisms needed at the block level for network attached disks.  ...

Efficient methodology for implementation of Encrypted File System in User Space [article]

Dr. Shishir Kumar, U.S. Rawat, Sameer Kumar Jasra, Akshay Kumar Jain
2009 arXiv   pre-print
Encryption techniques for file system level encryption are described, and general issues of cryptographic system interfaces to support routine secure computing are discussed.  ...  EFS supports secure storage at the system level through a standard UNIX file system interface to encrypted files. User can associate a cryptographic key with the directories they wish to protect.  ...  EFS pushes file encryption entirely into the client file system interface, and therefore does not suffer from many of the difficulties inherent in user level and disk and network based system level encryption  ...
