The VMM must implement cryptographic mechanisms to prevent unauthorized modification of all information at rest on all VMM components.

VMMs handling data requiring "data-at-rest" protections must employ cryptographic mechanisms to prevent unauthorized 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.

Verify the VMM implements cryptographic mechanisms to prevent unauthorized modification of all information at rest on all VMM components.

If it does not, this is a finding.

Configure the VMM to implement cryptographic mechanisms to prevent unauthorized modification of all information at rest on all VMM components.
