# CYBER SECURITY (Penetration Testing Prerequisites) 1.3 WireShark & Data Sniffing

**WireShark: **
do do do do, :D 



Wireshark is a network sniffer tool. a sniffer tool allows you to see the data transmitted over the network to and from the computer. 

- it's power full tool that can do many things like capture the network traffic and allow you to analyze it, I will discuss in depth how we can use it in a proper way,  but for now, I will show you how we will use it to know the difference between clear-text and cryptographic protocols.

if you need to know more about it you can check  [link](https://www.wireshark.org) 

You can check out this video which demonstrates the difference between HTTP and HTTPS, and how Wireshark capture the data
