I’ve been running my server without a firewall for quite some time now, I have a piped instance and snikket running on it. I’ve been meaning to get UFW on it but I’ve been too lazy to do so. Is it a necessary thing that I need to have or it’s a huge security vulnerability? I can only SSH my server from only my local network and must use a VPN if I wanna SSH in outside so I’d say my server’s pretty secure but not the furthest I could take it. Opinions please?
I like to run ufw on all my machines but I’m also a tinfoil-hat wearing wacko who believes that no computer should ever really be trusted. Just trusted enough to do specific tasks.
If someone somehow busts into one of my VLANs, at least the other machines on that net will still have some sort of protection.
