Chapter 3 Full Disk Encryption This chapter describes the Full Disk Encryption (FDE) feature and consists of the following sections: • Section 3.1, "Overview" • Section 3.2, "Purpose" • Section 3.3, "Terminology" • Section 3.4, "Workflow" 3.1 Overview The Full Disk Encryption feature offers the ability to encrypt data on drives and use disk-based key management to provide data security. This solution provides data protection in the event of theft or loss of physical drives. With self-encrypting drives, if you remove a drive from its storage system or the server it is housed in, the data on that drive is encrypted and useless to anyone who attempts to access without the the appropriate security authorization. With the FDE feature, data is encrypted by the drives. You can designate which data to encrypt at the individual virtual disk (VD) level. Any encryption solution requires management of the encryption keys. The security feature provides a way to manage these keys. Both the WebBIOS Configuration Utility (Section Figure 4.5, "WebBIOS Virtual Drive Definition Screen") and MegaRAID Storage Manager (Section 8.2, "Selecting Full Disk Encryption Security Options") offer procedures that you can use to manage the security settings for the drives.
