Security for the Storage Network Merging NAS and SAN
Dezhi Han, Jianzhong Huang · 2006
With the development of the networked storage and its application, the SNMNS (storage network merging NAS and SAN) came into being, which has such advantages as high performance, low cost, good connectivity and so on. But the security issue has become more complicated, because the SNMNS serves the block I/O requests and the file I/O requests at the same time. In that paper, we have developed a security system module used to the SNMNS to prevent it from many types of attacks. This module not only uses effective authentication to keep data of the system from being obtained by unauthorized users, but also offers data integrality checking and user authentication. The experimental results have shown that the security module not only can guard against both remote attacks and those who gain physical access to the SNMNS, but also can be seamlessly integrated into underlying file systems, with little influence on their performance
