01 Security

Is port 1036 dangerous?

We have no specific security note for port 1036. 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 1036, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1036'      # process listening on 1036
sudo lsof -nP -i :1036

macOS

sudo lsof -nP -i :1036

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1036 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1036
netstat -ano | findstr :1036

From another machine

nmap -p 1036 -sV <host>
sudo nmap -sU -p 1036 <host>
nc -zv <host> 1036

Block it in the firewall

sudo ufw deny 1036/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1036" -Direction Inbound -LocalPort 1036 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1036 used for?

Port 1036 is assigned by IANA to nsstp (Nebula Secure Segment Transfer Protocol).

Is port 1036 TCP or UDP?

Port 1036 is registered for TCP and UDP.

Is it safe to open port 1036?

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 1036 is open?

On Linux run "ss -ltnup 'sport = :1036'", on macOS "lsof -nP -i :1036", and on Windows "netstat -ano | findstr :1036" to see the local process. From another machine, "nmap -p 1036 <host>" shows whether it is reachable.
