Question 74

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?

  1. The firewall itself is blocking ports 21 through 23 and a service is listening on port 23 of the target host.
  2. The lack of response from ports 21 and 22 indicate that those services are not running on the destination server.
  3. The scan on port 23 passed through the filtering device. This indicates that port 23 was not blocked at the firewall.
