01 Security

Is port 3602 dangerous?

We have no specific security note for port 3602. 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 3602, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3602'      # process listening on 3602
sudo lsof -nP -i :3602

macOS

sudo lsof -nP -i :3602

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3602 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3602
netstat -ano | findstr :3602

From another machine

nmap -p 3602 -sV <host>
sudo nmap -sU -p 3602 <host>
nc -zv <host> 3602

Block it in the firewall

sudo ufw deny 3602/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3602" -Direction Inbound -LocalPort 3602 -Protocol TCP -Action Block  # Windows

What is port 3602 used for?

Port 3602 is assigned by IANA to infiniswitchcl (InfiniSwitch Mgr Client).

Is port 3602 TCP or UDP?

Port 3602 is registered for TCP and UDP.

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 3602 is open?

On Linux run "ss -ltnup 'sport = :3602'", on macOS "lsof -nP -i :3602", and on Windows "netstat -ano | findstr :3602" to see the local process. From another machine, "nmap -p 3602 <host>" shows whether it is reachable.
