Another way you can secure SSH is by setting up SSH passwordless authentication by use of ssh keys. Instead of using password authentication which is prone to brute force attacks, SSH keys are preferred as they only allow entry to users with the ssh key to to the remote server and block out any other user. The first step in enabling passwordless authentication is generating a key pair. ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with SSH protocol version 2. Root is disabled and only the user account specified at launch time (or the default cloud-user) is allowed to connect, preferably using ssh public key authentication.
