01 Security

Is port 1270 dangerous?

We have no specific security note for port 1270. 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 1270, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1270'      # process listening on 1270
sudo lsof -nP -i :1270

macOS

sudo lsof -nP -i :1270

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1270 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1270
netstat -ano | findstr :1270

From another machine

nmap -p 1270 -sV <host>
sudo nmap -sU -p 1270 <host>
nc -zv <host> 1270

Block it in the firewall

sudo ufw deny 1270/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1270" -Direction Inbound -LocalPort 1270 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1270 used for?

Port 1270 is assigned by IANA to opsmgr (Microsoft Operations Manager).

Is port 1270 TCP or UDP?

Port 1270 is registered for TCP and UDP.

Is it safe to open port 1270?

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 1270 is open?

On Linux run "ss -ltnup 'sport = :1270'", on macOS "lsof -nP -i :1270", and on Windows "netstat -ano | findstr :1270" to see the local process. From another machine, "nmap -p 1270 <host>" shows whether it is reachable.
