01 Security

Is port 4415 dangerous?

We have no specific security note for port 4415. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:

  • Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
  • Never expose them to the Internet.
  • Rotate tokens and certificates and audit who has access.

03 Check it

Which program uses port 4415, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4415'      # process listening on 4415
sudo lsof -nP -i :4415

macOS

sudo lsof -nP -i :4415

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4415 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4415
netstat -ano | findstr :4415

From another machine

nmap -p 4415 -sV <host>
nc -zv <host> 4415

Block it in the firewall

sudo ufw deny 4415/tcp                                         # Linux (ufw)

04 FAQ
What is port 4415 used for?

Port 4415 is assigned by IANA to brcd-vr-req (Brocade Virtual Router Request).

Is port 4415 TCP or UDP?

Port 4415 is registered for TCP.

Is it safe to open port 4415?

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. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.

How do I check if port 4415 is open?

On Linux run "ss -ltnup 'sport = :4415'", on macOS "lsof -nP -i :4415", and on Windows "netstat -ano | findstr :4415" to see the local process. From another machine, "nmap -p 4415 <host>" shows whether it is reachable.
