Question

What is fingerprinting in ethical hacking?

Answer 1

Fingerprinting is a method used to determine which operating system is running on a remote computer. There are two types of fingerprinting: 

1. Active fingerprinting: Specially crafted packets are sent to the target machine. The target OS is determined based on its response and collected data.
2. Passive fingerprinting: One can find out the OS of the remote host based on the sniffer traces of the packets.
