Title

RHEL 9 SSH daemon must display the date and time of the last successful account logon upon an SSH logon. (Cat II impact)

Discussion

Providing users feedback on when account accesses last occurred facilitates user recognition and reporting of unauthorized account use.

Check Content

Verify the SSH daemon provides users with feedback on when account accesses last occurred with the following command: $ sudo /usr/sbin/sshd -dd 2>&1 | awk '/filename/ {print $4}' | tr -d '\r' | tr '\n' ' ' | xargs sudo grep -iH '^\s*printlastlog' PrintLastLog yes If the "PrintLastLog" keyword is set to "no", the returned line is commented out, or no output is returned, this is a finding.

Fix Text

Configure the SSH daemon to provide users with feedback on when account accesses last occurred. Add the following line in "/etc/ssh/sshd_config", or uncomment the line and set the value to "yes": PrintLastLog yes The SSH service must be restarted for changes to take effect: $ sudo systemctl restart sshd.service
