The application server must implement cryptographic mechanisms to prevent unauthorized modification of organization-defined information at rest on organization-defined information system components.
Description
Discussion Text
Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive, tape drive) within an application server. Alternative physical protection measures include protected distribution systems.
To prevent unauthorized disclosure or modification of the information, application servers must protect data at rest by using cryptographic mechanisms.
Selection of a cryptographic mechanism is based on the need to protect the integrity of organizational information. The strength of the mechanism is commensurate with the security category and/or classification of the information. Organizations have the flexibility to either encrypt all information on storage devices (i.e., full disk encryption) or encrypt specific data structures (e.g., files, records, or fields).
