Question

What do you mean by fingerprinting in ethical hacking?

Answer 1

Fingerprinting is a technique used for determining which operating system is running on a remote computer.

1. Active fingerprinting: In this, we send the specially crafted packets to the target machine, and based on its response and gathered data, we determine the target OS.
2. Passive fingerprinting: In this, based on the sniffer traces of the packets, we can find out the OS of the remote host.
