01 Security

Is port 12007 dangerous?

We have no specific security note for port 12007. Its risk depends on the program actually listening on it. General advice for databases & caches services:

  • Bind the service to localhost or a private network, never to a public address.
  • Enable authentication, use per-application accounts and require TLS.
  • Watch for exposed Docker ports: publish them on 127.0.0.1 only.

03 Check it

Which program uses port 12007, and is it reachable?

Linux

sudo ss -ltnup 'sport = :12007'      # process listening on 12007
sudo lsof -nP -i :12007

macOS

sudo lsof -nP -i :12007

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 12007 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 12007
netstat -ano | findstr :12007

From another machine

nmap -p 12007 -sV <host>
sudo nmap -sU -p 12007 <host>
nc -zv <host> 12007

Block it in the firewall

sudo ufw deny 12007/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 12007" -Direction Inbound -LocalPort 12007 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 12007 used for?

Port 12007 is assigned by IANA to accuracer (Accuracer Database System Server).

Is port 12007 TCP or UDP?

Port 12007 is registered for TCP and UDP.

Is it safe to open port 12007?

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. Bind the service to localhost or a private network, never to a public address.

How do I check if port 12007 is open?

On Linux run "ss -ltnup 'sport = :12007'", on macOS "lsof -nP -i :12007", and on Windows "netstat -ano | findstr :12007" to see the local process. From another machine, "nmap -p 12007 <host>" shows whether it is reachable.
