Title

The SUBACID Control Option is not set to (U,8). (Cat II impact)

Discussion

The SUBACID Control Option indicates how TSS will derive an ACID for batch jobs that are submitted through an online terminal, from another batch job, or from a started task. 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 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 migration process or contingency plan activation.

Check Content

a) Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(STATUS) Automated Analysis Refer to the following report produced by the TSS Data Collection: - PDI(TSS0600) b) If the SUBACID Control Option values are set to SUBACID(U,8), there is NO FINDING. c) If the SUBACID Control Option values are NOT set to SUBACID(U,8), this is a FINDING.

Fix Text

Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option setting to SUBACID(U,8), and proceed with the change.
