Check that pam_lastlog is used, not silent, and configured to show failed logins. # grep pam_lastlog /etc/pam.d/sshd /etc/pam.d/common-session This is a finding unless: - pam_lastlog is present in sshd and common-session, or only common-session if sshd calls common-session with the session include statement. - pam_lastlog is not configured with the "silent" option. - pam_lastlog is configured with the "showfailed" option. |

Configure pam_lastlog. Edit /etc/pam.d/sshd or /etc/pam.d/common-session (if included from sshd) and make the following changes: - if pam_lastlog is not present, add it: "session required pam_lastlog.so showfailed" - if pam_lastlog has the "silent" option specified, remove it. - if pam_lastlog does not have the "showfailed" option specified, add it. |
