Hello, I'd like to know how to setup proper security on my dedicated server, I realized that the person I paid might've not properly configured everything so I need help with the ff: 1. I already made 2 new users for Multicraft since people were saying not to use the root user, is there anything else I need to change here? 2. How do I setup security via Putty, and what steps should I take to keep/make my dedi secure? Thanks!
