01 Security

Is port 710 dangerous?

We have no specific security note for port 710. 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 710, and is it reachable?

Linux

sudo ss -ltnup 'sport = :710'      # process listening on 710
sudo lsof -nP -i :710

macOS

sudo lsof -nP -i :710

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 710 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 710
netstat -ano | findstr :710

From another machine

nmap -p 710 -sV <host>
sudo nmap -sU -p 710 <host>
nc -zv <host> 710

Block it in the firewall

sudo ufw deny 710/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 710" -Direction Inbound -LocalPort 710 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 710 used for?

Port 710 is assigned by IANA to entrust-ash (Entrust Administration Service Handler).

Is port 710 TCP or UDP?

Port 710 is registered for TCP and UDP.

Is it safe to open port 710?

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 710 is open?

On Linux run "ss -ltnup 'sport = :710'", on macOS "lsof -nP -i :710", and on Windows "netstat -ano | findstr :710" to see the local process. From another machine, "nmap -p 710 <host>" shows whether it is reachable.
