Description
The CPFRCVUND Control Option indicates whether or not the local node can receive commands propagated from nodes which have not been defined to the CPFNODES list. 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(TSS0280) b) If the CPFRCVUND Control Option value is set to NO, There is NO FINDING. c) If the CPFRCVUND Control Option value is set to YES, this is a FINDING.

Fix Text (F-16738r1_fix)
The IAO will ensure CPFRCVUND 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 setting to NO and proceed with the change.
