• Question 332:

  You are having problems while retrieving results after performing port scanning during internal testing. You verify that there are no security devices between you and the target system. When both stealth and connect scanning do not work, you decide to perform a NULL scan with NMAP. The first few systems scanned shows all ports open.

  You are scanning into the target network for the first time. You find very few conventional ports open. When you attempt to perform traditional service identification by connecting to the open ports, it yields either unreliable or no results. You are unsure of which protocols are being used. You need to discover as many different protocols as possible.

  Which kind of scan would you use to achieve this? (Choose the best answer)

  A. Nessus scan with TCP based pings.

  B. Nmap scan with the P (Ping scan) switch.

  C. Netcat scan with the switches.
