Is port 7071 dangerous?

We have no specific security note for port 7071. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 7071, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7071'      # process listening on 7071
sudo lsof -nP -i :7071

macOS

sudo lsof -nP -i :7071

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7071 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7071
netstat -ano | findstr :7071

From another machine

nmap -p 7071 -sV <host>
sudo nmap -sU -p 7071 <host>
nc -zv <host> 7071

Block it in the firewall

sudo ufw deny 7071/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 7071" -Direction Inbound -LocalPort 7071 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 7071 used for?

Port 7071 is assigned by IANA to iwg1 (IWGADTS Aircraft Housekeeping Message).

Is port 7071 TCP or UDP?

Port 7071 is registered for TCP and UDP.

Is it safe to open port 7071?

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. Close the port if nothing on the host needs it.

How do I check if port 7071 is open?

On Linux run "ss -ltnup 'sport = :7071'", on macOS "lsof -nP -i :7071", and on Windows "netstat -ano | findstr :7071" to see the local process. From another machine, "nmap -p 7071 <host>" shows whether it is reachable.
