If you using firewalld then you need to use firewall-cmd --permanent switch to make permanent changes on firewall rules.

Fedora use Firewalld as firewall manager command is firewall-cmd you could start learning the basics here https://fedoraproject.org/wiki/FirewallD

Fedora also include SELinux already enabled and it enforce security within services and users, read more https://fedoraproject.org/wiki/SELinux

There you have the basics to understand Fedora Security of course you have the user and password rule sets that old unix/linux uses, there goes a bit more with corporative centralized accounts using kerberos and others systems you can also look into that.

Hope this help. Good Luck.

It sounds like you need an overview of the operating system and the main components related to system administration, since it is only by properly understanding and configuring the entirety of the operating system that one ensures its security.

I'd start with the Fedora 24 System Administrator's Guide. Completing it should give you a better understanding of the scope of operating system security and you'll be able to better formulate further questions. That will, in turn, make it easier for you to discover answers.

To the list of recommended security hardening tools I would also add:

OpenSCAP / scap-workbench

These tools will help you to check your system configuration related to security. There are many profiles / contents to choose from and thanks to scap-workbench, it's fairly easy to scan your system and customize the profiles.

aide

This tool (Fedora package link) is for file integrity checking. Based on the configuration it creates a database of files and their attributes, checksums, etc. and then periodically checks for differences. Unexpected changes of the file attributes could mean that your system was compromised. However, interpreting the scan results requires care and some technical knowledge.

USBGuard

For USB device related security, there's USBGuard (project link, Fedora package link) using which you can create a USB device whitelist.
