01 Security

Is port 715 dangerous?

We have no specific security note for port 715. 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 715, and is it reachable?

Linux

sudo ss -ltnup 'sport = :715'      # process listening on 715
sudo lsof -nP -i :715

macOS

sudo lsof -nP -i :715

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 715 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 715
netstat -ano | findstr :715

From another machine

nmap -p 715 -sV <host>
sudo nmap -sU -p 715 <host>
nc -zv <host> 715

Block it in the firewall

sudo ufw deny 715/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 715" -Direction Inbound -LocalPort 715 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 715 used for?

Port 715 is assigned by IANA to iris-lwz (IRIS-LWZ).

Is port 715 TCP or UDP?

Port 715 is registered for TCP and UDP.

Is it safe to open port 715?

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 715 is open?

On Linux run "ss -ltnup 'sport = :715'", on macOS "lsof -nP -i :715", and on Windows "netstat -ano | findstr :715" to see the local process. From another machine, "nmap -p 715 <host>" shows whether it is reachable.
