A) Passive footprinting is a method in which the attacker never makes contact with the target systems. The downside to the active method for an attacker is that many companies may log contact between an attacker and the target system.

8) What is a fingerprint in networking?

A) TCP/IP stack fingerprinting is the passive collection of configuration attributes from a remote device during standard layer 4 network communications. The combination of parameters may then be used to infer the remote machine's operating system (aka, OS fingerprinting), or incorporated into a device fingerprint.

9) What information hacker can collect during footprinting?

A) During this footprinting phase, a hacker can collect the following information,
