Enhancement: Add a Security Section

[LRomano72]

Hi,
I'm not a big Linux user and using your tool is great and helps save a lot of time but I found it strange that you didn't have a section for "security" tools/items to help enable even some of the basic security items that are found here:
https://www.raspberrypi.org/documentation/configuration/security.md or I'm sure there are other lists that are more exhaustive.
E.g. add a firewall with a GUI, or even enable/disable fail2ban, etc.

Just something that then more experts like yourselves that use Linux all the time can add a bunch of security scripts and tools that help lock down these devices for the average person that really uses a RPi for Kodi or other home projects and has little knowledge of Linux security. I think it will push people to learn, think and implement more security measures for everything they do.

Thanks for the great tool and scripts!
