Title
The ADSP (Automatic DataSet Protection) Control Option is not set to (NO). (Cat II impact)
Discussion
The ADSP Control Option allows the TSS administrator to determine whether newly created data sets will be automatically protected. 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(TSS0250) b) If the ADSP Control Option value is set to ADSP(NO), there is NO FINDING. c) If the ADSP Control Option value is NOT set to ADSP(NO), this is a FINDING.
Fix Text
The IAO will ensure ADSP control option is set to (NO) indicating that the RACF bit in the DSCB will not be set. Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option setting to ADSP(NO) and proceed with the change.
