[CentOS] CentOS 6.5 equivalents in CentOS 7

I tried to install CentOS 7 on a new system. It works.

However, I'm noticing small things:
1. system-config-network-tui is not installed and yum cannot find it. I
realized for this -- nmtui

What about firewall? I can't seem to understand the replacement from
system-config-firewall-tui
