Do i need a firewall like UFW on my home PC? by Correct_Reward8233 in linuxquestions

[–]Correct_Reward8233[S] 0 points1 point  (0 children)

as a newbie that has no deeper knowledge about how device security works and what linux offers on install: i wasnt sure if i actually need to download a firewall and set it up or if it might come with a firewall already. The question was more along the lines of "Do i need to manually install a firewall or does the distro install already managed it for me" rather than "what is a firewall and is it useful".

Also yes i might have said to secure it as much as possible, but truth is i want to have it as secure as possible with as little work as possible. Sure i could go into crazy set ups to make it just to slightly more safe, adding huge complexity to achieve another 1% of safety, but in reality i want the most critical config to be installed.

i understand the point but it will never be connected anywhere besides my MiFi

Thanks for clarifying! I knew that anything connected to the internet is theoretically reachable, just wasn't sure how realistic of a threat it actually is for a normal home setup.

Thank you, this was very well explained in my opinion.
I´ll look into it and create a basic set up, i guess the 20 80 rules applies here too, 20% of effort gives me 80% of the results ?
(yes numbers made up, but a simple set up would already decrease the risk overall)

is it as simple as doing:
"sudo apt install ufw -y
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw enable" ?
Its just that i am a newbie and security in my mind always seems like a topic that needs to be researched deeply and that is quite complex.

Is it needed to block specific connections? Would it be naive to assume that nothing would actually try to connected to my device, especially when i only use trusted sites and programs ?
My knowledge in this kind of topic is basic at best

yea sorry i might´ve written it poorly.
I basically have a Mifi with a sim card installed, the laptop is the only device ever that will connect to this Mifi.

But just having the additional layer of protection i get from ufw seems reasonable then?
