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 using 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

Restart the SSH service for changes to take effect:

$ sudo systemctl restart sshd.service
