| Description | ||||
| 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. | ||||

Check Text (C-223512r958552_chk)
From an ACF command screen enter:
SET CONTROL(GSO)
LIST SECVOLS
If the GSO SECVOLS record values conform to the following requirements, this is not a finding.
VOLMASK()
NOTE: Local changes will be documented in writing with supporting documentation.
If there is any deviation from the above requirements in the GSO SECVOLS record values, this is a finding.
Fix Text (F-25173r504607_fix)
Define the GSO SECVOLS record values to conform to the following requirements.
VOLMASK()
Example:
SET C(GSO)
INSERT SECVOLS VOLMASK()
