Hi. I wanted to know if it's needed to install a firewall on a linux desktop/laptop. Why yes or why no?

    It depends. Sure, maybe somewhat redundant for a home desktop that just stays at home on a network you control, but for a laptop it is absolutely essential.

    You may also want a firewall to defend against other devices within your local network. Let's say you have IoT devices, many of which are poorly secured and maintained by their manufacturers, or you live with family members or guests who don't practice or even know about proper computing hygiene and are bringing in devices onto your local WiFi.

      My IoT devices already have a dedicated network and guest can use my guest WiFi. But yes, you’re right. It depends. And especially for mobile devices some sort of local firewall solution could be relevant. If there are no ports exposed to the LAN you’re pretty save, though.

        No you aren't, browser based malware puts the attacker inside your fancy network. A basic firewall will greatly hinder any attack at basically no cost to you.
