01 Security

Is port 6076 dangerous?

We have no specific security note for port 6076. 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 6076, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6076'      # process listening on 6076
sudo lsof -nP -i :6076

macOS

sudo lsof -nP -i :6076

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6076 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6076
netstat -ano | findstr :6076

From another machine

nmap -p 6076 -sV <host>
nc -zv <host> 6076

Block it in the firewall

sudo ufw deny 6076/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6076" -Direction Inbound -LocalPort 6076 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 6076 used for?

Port 6076 is assigned by IANA to msft-dpm-cert (Microsoft DPM WCF Certificates).

Is port 6076 TCP or UDP?

Port 6076 is registered for TCP.

Is it safe to open port 6076?

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 6076 is open?

On Linux run "ss -ltnup 'sport = :6076'", on macOS "lsof -nP -i :6076", and on Windows "netstat -ano | findstr :6076" to see the local process. From another machine, "nmap -p 6076 <host>" shows whether it is reachable.
