I have blocked FTP 21 port on server. NOw every connection will be via SFTP via ssh.

Initially i had /etc/hosts.deny -- sshd:all

But i had to remove that otherwise sftp was not working.

How can i secure my shell login so that if someone login via root or userbac(root previleges)

Then i need private key but not for other users

Or any other to secure my system

Thanks
