01 Security

Is port 1054 dangerous?

We have no specific security note for port 1054. 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 1054, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1054'      # process listening on 1054
sudo lsof -nP -i :1054

macOS

sudo lsof -nP -i :1054

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1054 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1054
netstat -ano | findstr :1054

From another machine

nmap -p 1054 -sV <host>
sudo nmap -sU -p 1054 <host>
nc -zv <host> 1054

Block it in the firewall

sudo ufw deny 1054/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1054" -Direction Inbound -LocalPort 1054 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1054 used for?

Port 1054 is assigned by IANA to brvread (BRVREAD).

Is port 1054 TCP or UDP?

Port 1054 is registered for TCP and UDP.

Is it safe to open port 1054?

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 1054 is open?

On Linux run "ss -ltnup 'sport = :1054'", on macOS "lsof -nP -i :1054", and on Windows "netstat -ano | findstr :1054" to see the local process. From another machine, "nmap -p 1054 <host>" shows whether it is reachable.
