Details
Check Text (C-244541r1017347_chk)
To verify that null passwords cannot be used, run the following command:
$ sudo grep -i nullok /etc/pam.d/password-auth
If output is produced, this is a finding.
Fix Text (F-47773r743871_fix)
Remove any instances of the "nullok" option in the "/etc/pam.d/password-auth" file to prevent logons with empty passwords.
Note: Manual changes to the listed file may be overwritten by the "authselect" program.
