Physical Security:

There can be two physical security problems in a SAN.

• Data can be stolen
• Data can be lost or destroyed by natural disaster.

There are plenty of method which can prevent from loss with such problem such data  should be unreadable from unauthorized person , back up should be planned wisely etc.

Security in Transition:

When data transmits in the network, the data maybe sniffed or modified in the process of transition. Two methods that can  be applied to secure the data during transition are Using encryption, and strict protocol.

Access Control

In SAN environment, since every host connects with every storage device setting access privilege can prevent uncontrolled access. There are three types of access privilege setting method like Zone technology,LUN masking and IP SAN technology.

Planning for Security of Manage Console

All the security setting or policy are set on the manage console, so if anyone gain the access control of manage console, they will get what they want by changing the setting. So it is as important as protecting storage device. The security of manage console is mainly based on the OS. So some policy such as Strong authentication, strict accounting and audit requirements and  Intrusion detection system can be implemented.

While accessing the possibility of storage area network, Overall Risk assessment should be done on planning phase and security should be considered outside of box, hence implementing the security issue wisely.
