01 Security

Is port 9082 dangerous?

We have no specific security note for port 9082. 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 9082, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9082'      # process listening on 9082
sudo lsof -nP -i :9082

macOS

sudo lsof -nP -i :9082

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9082 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9082
netstat -ano | findstr :9082

From another machine

nmap -p 9082 -sV <host>
nc -zv <host> 9082

Block it in the firewall

sudo ufw deny 9082/sctp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 9082" -Direction Inbound -LocalPort 9082 -Protocol SCTP -Action Block  # Windows
04 FAQ
What is port 9082 used for?

Port 9082 is assigned by IANA to lcs-ap (LCS Application Protocol).

Is port 9082 TCP or UDP?

Port 9082 is registered for SCTP.

Is it safe to open port 9082?

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 9082 is open?

On Linux run "ss -ltnup 'sport = :9082'", on macOS "lsof -nP -i :9082", and on Windows "netstat -ano | findstr :9082" to see the local process. From another machine, "nmap -p 9082 <host>" shows whether it is reachable.
