In a recently posted white paper entitled “Decrypting Enterprise Storage Security”, Greg Schulz of the StorageIO Group discusses the options for encrypting and securing enterprise data and storage. He discusses in detail the method of employing encryption and tiered data security which allows multiple levels of security, depending upon the criticality and sensitivity of the data. The more critical the data, the more layers of security are applied.
Schulz specifically cites the Fujitsu ETERNUS architecture for its tiered data security capabilities. “Tiered data protection and security strategies can be deployed leveraging storage system-based encryption for data at rest combined with appliance-based encryption to protect data in-flight for local and remote mirror, replications and electronic tape vaulting. The Fujitsu ETERNUS with storage system-based encryption protects data with encryption on an individual LUN (logical unit number) or using volume granularity enabling the user to avoid treating all data the same. In other words, the ETERNUS enables the alignment of the appropriate level of security and encryption to counter applicable threat risks to the data.”
