I'm going to be setting up Centmin on CentOS 7. I was wondering if additional security hardening to the OS was necessary. I found the guide below and I was going to apply *some* of their recommendations. I wanted to check here on the forum before I started. Security Harden CentOS 7 Is there anything on the list the members / admin would recommend? Is there anything on the list the members / admin would advise NOT to do? Thanks!
