The TSO GSO record values must be set to the values specified.


Overview

Finding ID Version Rule ID IA Controls Severity
V-152 ACF0500 SV-152r3_rule DCCS-1 DCCS-2 Medium
Description
The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any one of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during a migration process or contingency plan activation.
