Which kind of scan would you use to do this?
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 what protocols are being used. You need to discover as many different protocols as possible. Which kind of scan would you use to do this?

What port scanning method involves sending spoofed packets to a target system and then looking for adjustments to the IPID on a zombie system?
What does this suggest ?
An Nmap scan shows the following open ports, and nmap also reports that the OS guessing results to match too many signatures hence it cannot reliably be identified:
21 ftp
23 telnet
80 http
443 https

What would you suggest to John to help identify the OS that is being used on the remote web server?
John has scanned the web server with NMAP. However, he could not gather enough information to help him identify the operating system running on the remote host accurately.

Which one of the following statements is probably true?
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.
