Anything open to access is part of the attack surface and can be attacked though whether this allows a successful hack is another matter.

The only way to secure a server is consider attacks and what you can do to prevent them.

In your case, you may have strong passwords, but are you going to know if someone tries your root account 506938 times with a brute force attack until they happen to find your password? Does your version of openssh have any security vulnerabilities that are remotely vulnerable? If you give someone else access, how do you know that they are changing things appropriately and not introducing vulnerabilities?
