| Check Text (C-18366r369570_chk) |
| Verify the SUSE operating system enforces a delay of at least four seconds between logon prompts following a failed logon attempt. # grep pam_faildelay /etc/pam.d/common-auth* auth required pam_faildelay.so delay=4000000 If the value of "delay" is not set to "4000000" or greater, "delay" is commented out, "delay" is missing, or the "pam_faildelay" line is missing completely, this is a finding. |

Add a parameter "pam_faildelay" and set it to a value of "4000000" or greater: # delay is in micro seconds auth required pam_faildelay.so delay=4000000 |
