Title

The IBM RACF INACTIVE SETROPTS value must be set to 35 days. (Cat II impact)

Discussion

Inactive identifiers pose a risk to systems and applications because attackers may exploit an inactive identifier and potentially obtain undetected access to the system. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. Operating systems need to track periods of inactivity and disable application identifiers after 35 days of inactivity.

Check Content

From a z/OS command input screen enter: List SETRopts If the INACTIVE value is set properly In the message "INACTIVE USERIDS ARE BEING AUTOMATICALLY REVOKED AFTER xxx DAYS.", where xxx is a value "35" or less, this is not a finding.

Fix Text

Configure the INACTIVE SETROPTS value to a value that is "35" or less. INACTIVE specifies the number of days that a USERID can remain unused and still be considered valid.
