How iadt-tls works

Other services
client:9614#%&@!x9response? client:9614#%&@!x9response?

The client sends a request to port 9614 and the iadt-tls service answers. Everything is encrypted: someone on the path only sees unreadable bytes.

01 Security

Is port 9614 dangerous?

We have no specific security note for port 9614. 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 9614, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9614'      # process listening on 9614
sudo lsof -nP -i :9614

macOS

sudo lsof -nP -i :9614

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9614 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9614
netstat -ano | findstr :9614

From another machine

nmap -p 9614 -sV <host>
nc -zv <host> 9614

Block it in the firewall

sudo ufw deny 9614/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 9614" -Direction Inbound -LocalPort 9614 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 9614 used for?

Port 9614 is assigned by IANA to iadt-tls (iADT Protocol over TLS).

Is port 9614 TCP or UDP?

Port 9614 is registered for TCP.

Is it safe to open port 9614?

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 9614 is open?

On Linux run "ss -ltnup 'sport = :9614'", on macOS "lsof -nP -i :9614", and on Windows "netstat -ano | findstr :9614" to see the local process. From another machine, "nmap -p 9614 <host>" shows whether it is reachable.
