Is port 3612 dangerous?

We have no specific security note for port 3612. 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 3612, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3612'      # process listening on 3612
sudo lsof -nP -i :3612

macOS

sudo lsof -nP -i :3612

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3612 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3612
netstat -ano | findstr :3612

From another machine

nmap -p 3612 -sV <host>
sudo nmap -sU -p 3612 <host>
nc -zv <host> 3612

Block it in the firewall

sudo ufw deny 3612/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3612" -Direction Inbound -LocalPort 3612 -Protocol TCP -Action Block  # Windows

What is port 3612 used for?

Port 3612 is assigned by IANA to dataprotector (Micro Focus Data Protector).

Is port 3612 TCP or UDP?

Port 3612 is registered for TCP and UDP.

Is it safe to open port 3612?

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 3612 is open?

On Linux run "ss -ltnup 'sport = :3612'", on macOS "lsof -nP -i :3612", and on Windows "netstat -ano | findstr :3612" to see the local process. From another machine, "nmap -p 3612 <host>" shows whether it is reachable.
