But taking a step back, it is interesting to examine where these features really belong. They were developed in storage systems to fill a need and each feature could be applied at a single point, regardless of the different hosts accessing the information.

To start a discussion about where the features really belong, let’s examine the more commonly used ones. This is not a call for change because change is unlikely.  It is a discussion that may assist in some understanding of how these features can help.

Encryption. Encryption should be done at the time an application creates or modifies data and before the data is transmitted out of the application’s control. This means the data would be encrypted when it is transmitted over any network to a storage location. Access to data from another server would require the authentication and the encryption keys for decrypting the data. Encrypting data at the storage system is not the best location because applications can access the data without controls regarding encryption. Encryption at the storage system is protection from physical theft of devices.
