Question 1: Describe port scanning utilities (or port scanners), which are tools used by both attackers and defenders to identify (or fingerprint) the computers that are active on a network, as well as the ports and services that are active on those computers, the functions and roles the machines are fulfilling, and other useful information.

Question 2: Explain how these tools can scan for specific types of computers, protocols, or resources, or their scans can be generic.

Question 3: Emphasize that the more specific the scanner is, the better it can give attackers and defenders information that is detailed and will be useful later.

Question 4: Note however, it is also recommended that you keep a generic, broad-based scanner in your toolbox as well.
