01 Security

Is port 8415 dangerous?

We have no specific security note for port 8415. 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 8415, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8415'      # process listening on 8415
sudo lsof -nP -i :8415

macOS

sudo lsof -nP -i :8415

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8415 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8415
netstat -ano | findstr :8415

From another machine

nmap -p 8415 -sV <host>
nc -zv <host> 8415

Block it in the firewall

sudo ufw deny 8415/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8415" -Direction Inbound -LocalPort 8415 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8415 used for?

Port 8415 is assigned by IANA to dlpx-sp (Delphix Session Protocol).

Is port 8415 TCP or UDP?

Port 8415 is registered for TCP.

Is it safe to open port 8415?

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 8415 is open?

On Linux run "ss -ltnup 'sport = :8415'", on macOS "lsof -nP -i :8415", and on Windows "netstat -ano | findstr :8415" to see the local process. From another machine, "nmap -p 8415 <host>" shows whether it is reachable.
