- Industrial and IoT protocols often have no authentication: never expose them to the Internet.
- Segment OT networks from IT and use protocol-aware firewalls.
- Monitor with an ICS-aware intrusion detection system.
Port 5094: HART-IP
Port 5094 is assigned by IANA to hart-ip (HART-IP).
How hart-ip works
IoT & industrial (ICS)A controller sends commands to an industrial device on port 5094, which acts on the physical process.

Is port 5094 dangerous?
We have no specific security note for port 5094. Its risk depends on the program actually listening on it. General advice for iot & industrial (ics) services:

Which program uses port 5094, and is it reachable?
Linux
sudo ss -ltnup 'sport = :5094' # process listening on 5094
sudo lsof -nP -i :5094macOS
sudo lsof -nP -i :5094
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 5094 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 5094 netstat -ano | findstr :5094
From another machine
nmap -p 5094 -sV <host> sudo nmap -sU -p 5094 <host> nc -zv <host> 5094
Block it in the firewall
sudo ufw deny 5094/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 5094" -Direction Inbound -LocalPort 5094 -Protocol TCP -Action Block # Windows
What is port 5094 used for?
Port 5094 is assigned by IANA to hart-ip (HART-IP).
Is port 5094 TCP or UDP?
Port 5094 is registered for TCP and UDP.
Is it safe to open port 5094?
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. Industrial and IoT protocols often have no authentication: never expose them to the Internet.
How do I check if port 5094 is open?
On Linux run "ss -ltnup 'sport = :5094'", on macOS "lsof -nP -i :5094", and on Windows "netstat -ano | findstr :5094" to see the local process. From another machine, "nmap -p 5094 <host>" shows whether it is reachable.
