01 Security

Is port 415 dangerous?

We have no specific security note for port 415. 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 415, and is it reachable?

Linux

sudo ss -ltnup 'sport = :415'      # process listening on 415
sudo lsof -nP -i :415

macOS

sudo lsof -nP -i :415

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 415 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 415
netstat -ano | findstr :415

From another machine

nmap -p 415 -sV <host>
sudo nmap -sU -p 415 <host>
nc -zv <host> 415

Block it in the firewall

sudo ufw deny 415/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 415" -Direction Inbound -LocalPort 415 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 415 used for?

Port 415 is assigned by IANA to bnet (BNet).

Is port 415 TCP or UDP?

Port 415 is registered for TCP and UDP.

Is it safe to open port 415?

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 415 is open?

On Linux run "ss -ltnup 'sport = :415'", on macOS "lsof -nP -i :415", and on Windows "netstat -ano | findstr :415" to see the local process. From another machine, "nmap -p 415 <host>" shows whether it is reachable.
