01 Security

Is port 713 dangerous?

We have no specific security note for port 713. 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 713, and is it reachable?

Linux

sudo ss -ltnup 'sport = :713'      # process listening on 713
sudo lsof -nP -i :713

macOS

sudo lsof -nP -i :713

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 713 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 713
netstat -ano | findstr :713

From another machine

nmap -p 713 -sV <host>
sudo nmap -sU -p 713 <host>
nc -zv <host> 713

Block it in the firewall

sudo ufw deny 713/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 713" -Direction Inbound -LocalPort 713 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 713 used for?

Port 713 is assigned by IANA to iris-xpc (IRIS over XPC).

Is port 713 TCP or UDP?

Port 713 is registered for TCP and UDP.

Is it safe to open port 713?

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 713 is open?

On Linux run "ss -ltnup 'sport = :713'", on macOS "lsof -nP -i :713", and on Windows "netstat -ano | findstr :713" to see the local process. From another machine, "nmap -p 713 <host>" shows whether it is reachable.
