Researching Network Storage Security Technology

Network storage time is called the third IT tide. The network storage technology has developed rapidly in the nearly 10 years, and has been applied to each profession. With the popular of the network storage, the security of network storage has been attended day by day. The security of the network storage includes the security of storage network and the data on the storage network.In this paper, after analyzing the risks and threats of the network storage, we provide the protect measures for the common network storage technology such as Network Attached Storage, Storage Area Network and the IP Storage. For the great capacity storage's protection, either physical side or electrical side, I think it needs"Deep Defence"secure stratagem for the every level storage. This way doesn't depend on simplex program or safeguard densely covering the whole storage network including host and network device and storage device, such as :(1) SAN storage protect function: Logical Unit Number, Masking and Zone are the common secure technology in order to authenticate the hosts that have authorization to access special storage disk array.(2) Data safeguard method: I design it with system root disk mirror, HA cluster, RAID level, redundancy path and remote mischance backup. It should cooperate with agile backup policy. I discover a backup way without business down time. It's effective for the never stop business.(3) At last, I suggest often evaluate SAN security with certain evaluation way such as two my creating SAN security evaluation matrix table. Then we can promote the related point security level according to the evaluation result.(4) The thesis subject, storage security, in one of the intedning IT hospots. It is very challenge to research and delivery, because it relates to storage and network and server security technology. Refer to myself limited experience and energy, the paper just focus on the actual field in my power. Through study plenty of storage security reference and developmental trend, I analyse all kinds of data security problem's countermeasure and evaluation methods.
