01 Security

Is port 14002 dangerous?

We have no specific security note for port 14002. Its risk depends on the program actually listening on it. General advice for network services services:

  • 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.

03 Check it

Which program uses port 14002, and is it reachable?

Linux

sudo ss -ltnup 'sport = :14002'      # process listening on 14002
sudo lsof -nP -i :14002

macOS

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

sudo ufw deny 14002/udp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 14002" -Direction Inbound -LocalPort 14002 -Protocol UDP -Action Block  # Windows
04 FAQ
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.
