How much do you secure a home server that's only accessible with VPN? (programming.dev)

I have a VPS that I secure as much as possible since the IP is public, but does a wireguard-access-only homelab warrant the same efforts? Those with homelabs like this, what do you do?

If it's just wireguard on a nonstandard port, then you are pretty much done. It's UDP and won't reply to incorrectly signed packets so it's essentially invisible.

    Putting it on a non standard port will change nothing

    Security through obscurity is not sufficient. It's also not nothing.

    Wireguard doesn't respond to port scans so it changes nothing

    Assume a security researcher finds a bug in wireguard that, if sent a malformed packet, it can crash the service. Then it would be trivialy easy to send that packet to the default port on every IP address and just crash everything for fun.

    It costs me nothing to increment the port by 1 and avoid all that drama.

    It is going to make fingerprinting more annoying while evading default port scans. That isnt nothing but you do you boo

    I agree that there is some value to obscurity generally, but Wireguard already evades port scans and fingerprinting. Unless a packet is signed with a known key, it gives no response to traffic, so scanners and fingerprinters see a closed port. You ISP can identify WG traffic while you are connected by inspecting your traffic, but random scanners won't see anything. Look on shodan, you won't see Wireguard.
