- 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.

Which program uses port 14002, and is it reachable?
Linux
sudo ss -ltnup 'sport = :14002' # process listening on 14002
sudo lsof -nP -i :14002macOS
sudo lsof -nP -i :14002
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 14002 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 14002 netstat -ano | findstr :14002
From another machine
nmap -p 14002 -sV <host> sudo nmap -sU -p 14002 <host> nc -zv <host> 14002
Block it in the firewall

What is port 14002 used for?
Port 14002 is assigned by IANA to scotty-disc (Discovery of a SCOTTY hardware codec board).
Is port 14002 TCP or UDP?
Port 14002 is registered for UDP.
Is it safe to open port 14002?
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 14002 is open?
On Linux run "ss -ltnup 'sport = :14002'", on macOS "lsof -nP -i :14002", and on Windows "netstat -ano | findstr :14002" to see the local process. From another machine, "nmap -p 14002 <host>" shows whether it is reachable.
