Storage Security has more moving parts than ever especially considering the convergence of IP and storage networking technologies. The type of storage includes ephemeral, long-term disk, and raw disk.

Different storage types of ISO 27040 such as SAN, NAS, DAS Security, Cloud Storage Security are very helpful to identify important security issues and provide guidance for storage management security for block-based systems and research and best practices for the network attacks.

Encryption can happen at a variety of levels of a computer's infrastructure. Data can be encrypted at the database level, with the added benefit of being able to apply encryption at the column or table space level.

A cryptographic key is used for one purpose only, so it is a best practice not to reuse those keys. Ephemeral keys should be used for data and fly it, and long-term keys for data at rest. It is advisable to keep the data encryption and other keys separate and use randomly chosen keys.

SED stands for self-encrypting drives and in this model cryptographic processing takes place on the chips that are co-located in the drive itself.

Key management is the management of cryptographic keys and encrypts the system, this includes dealing with the generation exchange storage use and even the replacement of these keys. The top three critical best practices in key management are Key management workflows, Key mgmt. practices and Crypto life cycle management.

Big Data is a broad term for data sets, so large or complex that traditional data processing applications are inadequate. Big Data is defined by significant data volume variety and volume.
