Check Text (C-73299r1048180_chk)
Verify the SSH daemon provides users with feedback on when account accesses last occurred with the following command:

$ sshd -T | grep printlastlog

printlastlog yes

If the value is returned as "no", this is a finding.
Fix Text (F-73200r1048181_fix)
Configure the SSH daemon to provide users with feedback on when account accesses last occurred.

Add the following line to "/etc/ssh/sshd_config", or uncomment the line and set the value to "yes":

PrintLastLog yes

Alternatively, add the setting to an include file if the line "Include /etc/ssh/sshd_config.d/*.conf" is found at the top of the "/etc/ssh/sshd_config" file:

$ echo 'PrintLastLog yes' > /etc/ssh/sshd_config.d/40-lastlog.conf

Restart the SSH daemon for the settings to take effect:

$ systemctl restart sshd.service
