- Answer only the networks that need the service (no open resolvers, relays or reflectors).
- UDP services can be abused for DDoS amplification: rate-limit or block them at the edge.
- Disable legacy test services that have no use in production.

What is port 48050 used for?
Port 48050 is assigned by IANA to weandsf (WeFi Access Network Discovery and Selection Function).
Is port 48050 TCP or UDP?
Port 48050 is registered for TCP.
Is it safe to open port 48050?
It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Answer only the networks that need the service (no open resolvers, relays or reflectors).
How do I check if port 48050 is open?
On Linux run "ss -ltnup 'sport = :48050'", on macOS "lsof -nP -i :48050", and on Windows "netstat -ano | findstr :48050" to see the local process. From another machine, "nmap -p 48050 <host>" shows whether it is reachable.
