From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hello fellow Linux enthusiasts!

As many of you know, Linux can be a powerful and flexible operating system, but it can also be daunting for new users, especially when it comes to securing their systems. With the abundance of information available online, it's easy to get overwhelmed and confused about the best practices for firewall configuration and basic security.

That's why I reaching out to the Linux community for help. I am looking users who are willing to share their expertise and write a comprehensive guide to Linux firewall and security.

The goal of this guide is to provide a centralized resource that covers the following topics:

Introduction to Linux firewalls (e.g., firewalld, ufw, etc.)
Understanding basic security principles (e.g., ports, protocols, network traffic)
Configuring firewalls for various scenarios (e.g., home networks, servers, VPNs)
Best practices for securing Linux systems (e.g., password management, package updates, file permissions)
Troubleshooting common issues and errors
Advanced topics (e.g., network segmentation, SELinux, AppArmor)

I am looking for a well-structured and easy-to-follow guide that will help new users understand the fundamentals of Linux firewall and security, while also providing advanced users with a comprehensive resource for reference.

If you're interested in contributing to this project, please reply to this post with your experience and expertise in Linux firewall and security. We'll be happy to discuss the details and work together to create a high-quality guide that benefits the Linux community.

Thank you for your time and consideration, and im looking forward to hearing from you!

This is all true… but a firewall takes no effort. It is the default on many OSes. Why not.

but a firewall takes no effort.

this whole thread is literally asking for people to put effort to collectivelly write a huge ass complete guide about linux firewalls targeting new users. So what I understand is that both the authors and the readers will have to put effort in either explaining or understanding and learning. We are not talking about a sudo apt install gufw and call it a day.

You can write a guide about anything. It really is simple in the common case.
