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?
Possibly it’s about personality types. I was only going on my own experience. Of always being told by a chorus of experts “Oh no you don’t want to do that!” and ending up being terrified to touch anything. When I now know that I usually had nothing to be afraid of, because dangerous things tend to be locked down by design, exactly as they should be.
