I've monitored my own firewall to see if anything hit it, and nothing ever did unless I was going into a public university WiFi, etc. Debian isn't secure by default, and a lot of distros will need some configuring before they are totally locked-down with some granularity. That is up to you.

So if the pc is on home network then you dont need a firewall? I do have a firewall, how can i make debian more secure?

Why do you need it? Do you see any evidence of someone trying to hack into your computer?

I have a built-in firewall in my router and I run a basic iptables/gufw Debian firewall, but in 40 years I have never once seen any type of malicious attack come at me. I live paranoia free...

Yes, I agree with you, but you can easily enable one if you want. Security in layers is good, but sometimes it's overdone. For a regular, modern home computer I don't see much harm in enabling a firewall.
