Is port 1184 dangerous?

We have no specific security note for port 1184. Its risk depends on the program actually listening on it. General advice for web services:

  • Serve it over HTTPS only and check the HTTP security headers.
  • Keep admin consoles and development servers off the Internet.
  • Patch the application server and remove default credentials and sample apps.

03 Check it

Which program uses port 1184, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1184'      # process listening on 1184
sudo lsof -nP -i :1184

macOS

sudo lsof -nP -i :1184

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1184 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1184
netstat -ano | findstr :1184

From another machine

nmap -p 1184 -sV <host>
sudo nmap -sU -p 1184 <host>
nc -zv <host> 1184

Block it in the firewall

sudo ufw deny 1184/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1184" -Direction Inbound -LocalPort 1184 -Protocol TCP -Action Block  # Windows
