CAT II
ACF2 SECVOLS GSO record value must be set to VOLMASK(). Any local changes are justified and documented with the ISSO.
From: IBM z/OS ACF2 Security Technical Implementation Guide (V9R8)
Description
<VulnDiscussion>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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
