Is port 1107 dangerous?

We have no specific security note for port 1107. 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 1107, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1107'      # process listening on 1107
sudo lsof -nP -i :1107

macOS

sudo lsof -nP -i :1107

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1107 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1107
netstat -ano | findstr :1107

From another machine

nmap -p 1107 -sV <host>
sudo nmap -sU -p 1107 <host>
nc -zv <host> 1107

Block it in the firewall

sudo ufw deny 1107/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1107" -Direction Inbound -LocalPort 1107 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1107 used for?

Port 1107 is assigned by IANA to isoipsigport-2 (ISOIPSIGPORT-2).

Is port 1107 TCP or UDP?

Port 1107 is registered for TCP and UDP.

Is it safe to open port 1107?

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 1107 is open?

On Linux run "ss -ltnup 'sport = :1107'", on macOS "lsof -nP -i :1107", and on Windows "netstat -ano | findstr :1107" to see the local process. From another machine, "nmap -p 1107 <host>" shows whether it is reachable.
