01 Security

Is port 8015 dangerous?

We have no specific security note for port 8015. 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 8015, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8015'      # process listening on 8015
sudo lsof -nP -i :8015

macOS

sudo lsof -nP -i :8015

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8015 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8015
netstat -ano | findstr :8015

From another machine

nmap -p 8015 -sV <host>
nc -zv <host> 8015

Block it in the firewall

sudo ufw deny 8015/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8015" -Direction Inbound -LocalPort 8015 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8015 used for?

Port 8015 is assigned by IANA to cfg-cloud (Configuration Cloud Service).

Is port 8015 TCP or UDP?

Port 8015 is registered for TCP.

Is it safe to open port 8015?

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 8015 is open?

On Linux run "ss -ltnup 'sport = :8015'", on macOS "lsof -nP -i :8015", and on Windows "netstat -ano | findstr :8015" to see the local process. From another machine, "nmap -p 8015 <host>" shows whether it is reachable.
