On a new linux install or image I will always:
I hope it is not a passwordless sudo, it is basically the same as root.
That's more or less the advice I've gotten as well. I've also read good things about fail2ban which tries to ban sources of repeated authentication failures to prevent brute force password attempts. I've used it, but the only person who has managed to get banned is myself! I did get back in after the delay, but I'm happy to know it works.
