Fix Recommendation

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

Check Contents

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.
