01 Security

Is port 5724 dangerous?

We have no specific security note for port 5724. 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 5724, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5724'      # process listening on 5724
sudo lsof -nP -i :5724

macOS

sudo lsof -nP -i :5724

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5724 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5724
netstat -ano | findstr :5724

From another machine

nmap -p 5724 -sV <host>
sudo nmap -sU -p 5724 <host>
nc -zv <host> 5724

Block it in the firewall

sudo ufw deny 5724/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5724" -Direction Inbound -LocalPort 5724 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5724 used for?

Port 5724 is assigned by IANA to omsdk (Operations Manager - SDK Service).

Is port 5724 TCP or UDP?

Port 5724 is registered for TCP and UDP.

Is it safe to open port 5724?

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 5724 is open?

On Linux run "ss -ltnup 'sport = :5724'", on macOS "lsof -nP -i :5724", and on Windows "netstat -ano | findstr :5724" to see the local process. From another machine, "nmap -p 5724 <host>" shows whether it is reachable.
