Firewalk has just completed the second phase (the scanning phase) and a technician receives the output shown below. What conclusions can be drawn based on these scan results?
- The firewall itself is blocking ports 21 through 23 and a service is listening on port 23 of the target host.
- The lack of response from ports 21 and 22 indicate that those services are not running on the destination server.
- The scan on port 23 passed through the filtering device. This indicates that port 23 was not blocked at the firewall.
- The scan on port 23 was able to make a connection to the destination host prompting the firewall to respond with a TTL error.
