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.

I am not sure. I personally don’t trust selinux because it was developed my the nsa, though that is just me being tinfoil-hat-ish about it. I am a fan of clamav / clamtk for files you think are sketchy (“alternatively obtained” games and things.) I also use ufw but that is more of a thing for servers if I’m not mistaken. If you use ssh server on your laptop, you should get fail2ban or sshguard. While the whole “Linux can’t get hacked” thing is wrong, as long as you stay updated and don’t be stupid you should be protected from automated scripts which is all desktop users really need to worry about.

Thanks for the time to anwser. What is the diffrents between ufw and systemds firewall ?

[–] Helix@feddit.de 0 points 1 year ago (5 children)

Which systemd firewall are you talking about?

Use UFW - uncomplicated firewall. Some distros install it by default. Its very easy to use whereas other firewalls are super complicated

I currently use firewalld is their a diffrents in terms of security ?

No, only the configuration syntax is different. If you know what you're doing in configuring them both are fine.

They're pretty similar but firewalld allows more complex rules without resorting to plain iptables syntax. Try both and see what you like better.
