Description
The DL1B Control Option is used to implement PSB and DBD security for IMS batch regions, and to provide access to the TSS application interface program. 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.

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(TSS0350) b) If the DL1B Control Option value is set to DL1B(NO), there is NO FINDING. c) If the DL1B Control Option value is set to DL1B(YES), this is a FINDING.

Fix Text (F-17042r1_fix)
The IAO will ensure DL1B control option is set to (NO) Evaluate the impact associated with implementation of the control option. Develop a plan of action to set the control option value to DL1B(NO) and proceed with the change.
