Improper assignments of attributes in the LOGONID record may allow users excessive privileges resulting in unauthorized access.
Refer to the following reports produced by the ACF2 Data Collection: - ACF2CMDS.RPT(TSOUSERS) - ACF2CMDS.RPT(MAXDAYS0) - ACF2CMDS.RPT(MAXDAYS) - ACF2CMDS.RPT(MINDAYS) Automated Analysis Refer to the following report produced by the ACF2 Data Collection Checklist: - PDI(ACF0570) Verify that the interactive userids are properly defined. If the following guidance is true, this is not a finding. ___ Ensure that all logonid record fields for interactive users are specified as in the table entitled INTERACTIVE USERS - ACF2, in the z/OS STIG Addendum. ___ Ensure that MAXDAYS is a value of 1 to 60 days. Note: Current DoD policy has changed requiring that the password change interval is set to a value of 1 to 60. Ensure that this is in effect. Note: FTP only process and server to server userids may have MAXDAYS(0) and LIDZMAX specified. These users must be identified in the FTPUSERS group in the Dialog Process or FTP in the name field. Additionally, these users must change their passwords on an annual basis.
