I have a 2 part question:
1. Is it a good idea to ban IP addresses by region on our server to increase our security? We mainly supply locally in our own country and do not need to be visible everywhere. Only a selected amount of countries. I do see numerous port scans coming from some countries that we would like to permanently limit access.
2. Where can we find these IPs and will it hinder the performance of the website and server if we have these bans in place.
Your comments are appreciated.
