Description
The NPPTHRESH Control Option sets the threshold value for the number of attempts allowed for new password re-verification before complete logon sequence needs restarting. In accordance with DODI 8500.2 for DOD information systems processing sensitive information and above, and CJCSM 6510.01, the following recommendations concerning password requirements are mandatory and apply equally to both classified and unclassified systems: 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.
