Security

In this chapter, we provide an overview of the need for security. We describe the available techniques and several key points.

9.1 Security in the storage area network

Security is always a major concern for networked systems administrators and users. Even for specialized networked infrastructures, such as a storage area network (SAN), special care must be taken so that information does not get corrupted, either accidentally or deliberately, or fall into the wrong hands. And, we also must ensure that the correct security is in place at ...
