ACF2 SECVOLS GSO record value must be set to VOLMASK(). Any local changes are justified and documented with the ISSO.

The SECVOLS record defines the DASD and tape volumes for which CA-ACF2 provides volume-level protection. Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive and tape drive, when used for backups) within an operating system.

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.
