A port scan returns an ‘open’ response. What does this mean?

  • A service is listening on the port
  • Connections to the port will be denied
  • There was no reply from the host

Explanation: An ‘open’ or ‘accepted’ response from a port scan indicates that a port or service is running on the computer and can be accessed by other network devices. This confirms that a specific service is actively listening on that port for incoming communications.
