1. Introduction to series of Wifi Penetration Testing

Hi guys, from today we are going to learn penetration testing of wifi networks. In this series we will see how a hacker attack your networks, what are steps that you can take to protect yourself, what are tools and minimum requirements to do penetration testing on wifi network. If you are a beginner and you do not know even a single terminology about wifi basics, do not worry at all, this is the right place for you. I am assuring you if you read my posts regularly and try to implement these in your daily life then you will learn a lot from this series without any prior knowledge.
So let us start with very basic knowledge of wifi security standards. This post will only tell you about the security standards used in wifi networks and their differences.
There are mainly three types of security standard we can use for securing and protecting our wifi network. These are as follows.

• WEP (Wired Equivalent Privacy)
• WPA (Wifi Protected Access)
• WPA2

The differences in these standard are given below in the table.

Encryption	How it works	Security Level
WEP(Wired Equivalent Privacy)	It uses RC4 stream cipher. It uses 64 or 128 bit key. It is easily and 100% hackable.	Low
WPA(Wi-Fi Protected Access)	It has backward compatibility with WEP devices. It also uses RC4 stream cipher but here the key size is 256 bit. In this each client get new keys with TKIP.	Medium
WPA2	This is the latest standard of encryption and nowadays we are using it. It replaces RC4 and TKIP with CCMP and AES algorithm.	High

So this is all about my first post. Patience is necessary for learning anything. I am going to teach you everything from scratch so that you do not feel any problem in later time when i will explain those complex topics.

Your feedback plays a very important role to encourage me for writing next post..

Thanks for your precious time..

 Enjoy learning.............
