SLEM 5 must display the date and time of the last successful account logon upon an SSH logon.

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

Verify all remote connections via SSH to SLEM 5 display 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'
     /etc/ssh/sshd_config:PrintLastLog yes

If the "PrintLastLog" is not set to "yes", is commented out, missing, or conflicting results are returned, this is a finding.

Configure SLEM 5 to provide users with feedback on when account accesses last occurred.

Add or modify the following lines in the "/etc/ssh/sshd_config" file:

PrintLastLog yes

Restart the SSH daemon in order for the changes to take effect:

     > sudo systemctl restart sshd.service
