How can I keep my forwarded port secure? (kbin.earth)

I just setup a minecraft server on an old laptop, but to make it acessible i needed to open up a port. Currently, these are the ufw rules i have. when my friends want to connect, i will have them find their public ip and ill whilelist only them. is this secure enough? thanks

Ha. That's my bad. I didn't even read the firewall rules listing 22/SSH. I agree on not opening 22 to the world. It just invites bots throwing passwords at it.

I just read Minecraft in the original post which from reading runs from 25565 which I wouldn't worry about. If OP needs 22 for admission I'd either whitelist it or use a VPN/Tailscale.

25565 also gets a decent amount of malicious traffic because of Minecraft though. I'd recommend switching the port to something different at the very least. When I hosted a server for the first time on 25565 my router pretty immediately gave me warnings about attempted network traffic coming from Europe/Asia when I (and everyone I gave the IP to) live in the US.
