Operating systems handling data requiring "data-at-rest" protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. 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). Satisfies: SRG-OS-000404-GPOS-00183, SRG-OS-000405-GPOS-00184
Review the requirements by the Information Owner to discover whether the system stores sensitive or classified information. If the system does not store sensitive or classified information, this is not applicable. Verify that data-at-rest encryption is enabled by entering the following command: cli% controlencryption status Licensed | Enabled | BackupSaved | State | SeqNum | Keystore yes | Yes | no | normal | 0 | --- If the "Enabled" flag is not set to "Yes" as shown in the output above, this is a finding.
Contact an authorized installer to enable the data-at-rest encryption feature. The data-at-rest encryption feature has hardware and licensing prerequisites that must be verified by an authorized installer prior to enabling the feature.
