Details

Check Text (C-260570r1082233_chk)

Verify that null passwords cannot be used. Run the following command: $ grep nullok /etc/pam.d/common-auth /etc/pam.d/common-password If this produces any output, this is a finding.

Fix Text (F-64207r1082232_fix)

Remove any instances of the "nullok" option in "/etc/pam.d/common-password" to prevent logons with empty passwords. Remove any instances of the "nullok" option in "/etc/pam.d/common-auth" and "/etc/pam.d/common-password".
