|SC-28 (1) Cryptographic Protection || |
Selection of cryptographic mechanisms is based on the need to protect the confidentiality and integrity of organizational information. The strength of mechanism is commensurate with the security category and/or classification of the information. This control enhancement applies to significant concentrations of digital media in organizational areas designated for media storage and also to limited quantities of media generally associated with information system components in operational environments (e.g., portable storage devices, mobile devices). 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). Organizations employing cryptographic mechanisms to protect information at rest also consider cryptographic key management solutions.
The information system implements cryptographic mechanisms to prevent unauthorized disclosure and modification of Assignment: organization-defined information on Assignment: organization-defined information system components.
|SC-28 (2) Off-Line Storage || |
Removing organizational information from online information system storage to off-line storage eliminates the possibility of individuals gaining unauthorized access to the information through a network. Therefore, organizations may choose to move information to off-line storage in lieu of protecting such information in online storage.
The organization removes from online storage and stores off-line in a secure location Assignment: organization-defined information.
