Is port 5362 dangerous?

We have no specific security note for port 5362. 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 5362, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5362'      # process listening on 5362
sudo lsof -nP -i :5362

macOS

sudo lsof -nP -i :5362

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5362 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5362
netstat -ano | findstr :5362

From another machine

nmap -p 5362 -sV <host>
sudo nmap -sU -p 5362 <host>
nc -zv <host> 5362

Block it in the firewall

sudo ufw deny 5362/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5362" -Direction Inbound -LocalPort 5362 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5362 used for?

Port 5362 is assigned by IANA to serverwsd2 (Microsoft Windows Server WSD2 Service).

Is port 5362 TCP or UDP?

Port 5362 is registered for TCP and UDP.

Is it safe to open port 5362?

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 5362 is open?

On Linux run "ss -ltnup 'sport = :5362'", on macOS "lsof -nP -i :5362", and on Windows "netstat -ano | findstr :5362" to see the local process. From another machine, "nmap -p 5362 <host>" shows whether it is reachable.
