How Can I secure My XRP Validator or Codius Host?
The simplest way one can secure their publicly accessible server, is through the means of Public/Private Key Authentication. Once you remove passwords from an external entry point, then it becomes nearly impossible to brute force a login and gain access to the server. I go over how to setup the private key access and remove the regular password login. You could even go as far as removing port 22 as well, but may not be something you want to do.
Is it hard to do?
Absolutely not. It can be done in as short as a few minutes given that you follow my video instructions.
However, if you do have issues do not hesitate to reach out to me and I can help you.
