01 Security

Is port 1132 dangerous?

We have no specific security note for port 1132. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:

  • Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
  • Never expose them to the Internet.
  • Rotate tokens and certificates and audit who has access.

03 Check it

Which program uses port 1132, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1132'      # process listening on 1132
sudo lsof -nP -i :1132

macOS

sudo lsof -nP -i :1132

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1132 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1132
netstat -ano | findstr :1132

From another machine

nmap -p 1132 -sV <host>
sudo nmap -sU -p 1132 <host>
nc -zv <host> 1132

Block it in the firewall

sudo ufw deny 1132/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1132" -Direction Inbound -LocalPort 1132 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1132 used for?

Port 1132 is assigned by IANA to kvm-via-ip (KVM-via-IP Management Service).

Is port 1132 TCP or UDP?

Port 1132 is registered for TCP and UDP.

Is it safe to open port 1132?

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. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.

How do I check if port 1132 is open?

On Linux run "ss -ltnup 'sport = :1132'", on macOS "lsof -nP -i :1132", and on Windows "netstat -ano | findstr :1132" to see the local process. From another machine, "nmap -p 1132 <host>" shows whether it is reachable.
