20.60 Ensure 'Systems requiring data at rest protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest'

Information

This policy setting ensures that systems requiring data at rest protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest.

Encrypting data at rest protects the organization from the physical theft of the file system storage devices. It can also protect the organization from unauthorized access to computer data.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Configure systems that require additional protections due to factors such as inadequate physical protection or sensitivity of the data to employ encryption to protect the confidentiality and integrity of all information at rest.

Note: This requirement addresses protection of user-generated data as well as operating system-specific configuration data. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate, in accordance with the security category and/or classification of the information.

Impact:

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).
