In this chapter, we looked at some brief descriptions of the topics that will be thoroughly covered in this book. We discussed using a Linux machine to hack a computer with the Windows operating system. Then, we learned about the concept of hacking through the use of real-time examples. The different types of hackers were discussed. Finally, we saw various applications involved in hacking.

In the following chapter, we will set up a virtual environment to perform various penetration tests. We will also install Kali Linux, Windows, and Metaspoitable machines.
