Description
(RACF0440: CAT II) INTERVAL specifies the maximum number of days that each users password is valid. When a user logs on to the system, RACF compares the system password interval value specified in the user profile. RACF uses the lower of the two values to determine if the users password has expired. 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.

Fix Text (F-17178r1_fix)
The IAO will ensure that PASSWORD(INTERVAL) SETROPTS value is set to 60 days. This specifies the maximum number of days that each user’s password is valid. Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option as specified in the example below: The RACF Command SETR LIST will show the status of RACF Controls including PASSWORD INTERVAL. (1) Setting the password interval to 60 days is activated with the command SETR PASSWORD(INTERVAL(60)).
