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
`Status: active
To Action From
22/tcp ALLOW Anywhere Anywhere ALLOW my.pcs.local.ip`
also, minecraft is installed under a separate user, without root privlege
A port is not secure or insecure. The thing that can lead to security risks is the service that answers that port.
Use strong authentication and encryption on those services and keep them up to date.
You can add IPS to port to add some security checking, but yes, in general port is never secure or unsecure.
