Is port 3072 dangerous?

We have no specific security note for port 3072. Its risk depends on the program actually listening on it. General advice for monitoring & logging services:

  • Restrict management and monitoring protocols to the monitoring network.
  • Replace community strings and default credentials.
  • Send logs over TLS.

03 Check it

Which program uses port 3072, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3072'      # process listening on 3072
sudo lsof -nP -i :3072

macOS

sudo lsof -nP -i :3072

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3072 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3072
netstat -ano | findstr :3072

From another machine

nmap -p 3072 -sV <host>
sudo nmap -sU -p 3072 <host>
nc -zv <host> 3072

Block it in the firewall

sudo ufw deny 3072/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3072" -Direction Inbound -LocalPort 3072 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3072 used for?

Port 3072 is assigned by IANA to csd-monitor (ContinuStor Monitor Port).

Is port 3072 TCP or UDP?

Port 3072 is registered for TCP and UDP.

Is it safe to open port 3072?

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. Restrict management and monitoring protocols to the monitoring network.

How do I check if port 3072 is open?

On Linux run "ss -ltnup 'sport = :3072'", on macOS "lsof -nP -i :3072", and on Windows "netstat -ano | findstr :3072" to see the local process. From another machine, "nmap -p 3072 <host>" shows whether it is reachable.
