A port scan returns a ‘dropped’ 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: A ‘dropped’ response (also referred to as ‘filtered’ or ‘blocked’) means that access to the port or service is blocked by a firewall. In this state, the firewall or security appliance discards the probing packet without sending a response, ensuring the port cannot be reached or exploited.
