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