Check Text (C-237900r858930_chk)

Display the System Configuration File. If the "JOURNALING" statement is set to: Facility ON LOGON Lockout after three attempts for 15 minutes, this is not a finding. Note: Site may set Lockout value at 0, this will require system administrator action for reset. Issue "QUERY JOURNAL" command. If the response is as follows this is not a finding: Journal: LOGON-on

Fix Text (F-41069r858929_fix)

Configure the System Configuration "JOURNALING" statement to: Facility ON LOGON Lockout after 3 attempts for 15 minutes or 0 if system administrator action is desired.
