For me the port number change is the easiest and also 90% the battle. I tried keyless entry, and locked myself out of my VPS. it's not as foolproof as it sounds like. It worked for a week or so, and then all of a sudden locked me out. I don't think it is really that necessary when there are so many other ways to secure the VPS to go for keyless entry. Changing a port number is very simple and easy to do. And I found enough for me. It sorts out about 99% of bot traffic.
