Title

The MSUSPEND Control Option is not set to (YES). (Cat II impact)

Discussion

The MSUSPEND Control Option allows the MSCA ACID to be suspended automatically if the password violation threshold is set via the PTHRESH option and that limit is exceeded. This will prevent a user from making an unlimited number of guess attempts to determine the MSCAs password. 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.
