Lecture Transcript - Network Penetration Testing Introduction

The first penetration testing section in this course is going to be the network hacking section. The reason why I chose to start with this because everything if you think of it, is connected to a network. So whether your target is a personal computer, whether it's a server, whether it's a company, or even if it's just a website, all of these systems are actually connected to a network. Literally, when you just connect to the internet, you're connected to a network because the internet is just a really, really big network. So it is very important that you understand how networks work and how devices communicate with each other before we actually move into the next sections. So this section is actually going to be divided into three subsections and in the first subsection, we're going to talk about all of the attacks that you can do before connecting to a network. So you literally just have a computer with the network interface, possibly a Wi-Fi adapter, and we're going to see what can you do now before even connecting to anything? And the second subsection, I'm going to show you how to crack wifey keys and gain access to Wi-Fi networks, whether they use debut EP, WPA or WPA to. Once you have the access, you can move to the third section, which will apply to both Wi-Fi and wired networks.

All of the attacks that you will learn in the third subsection apply whenever you are able to connect to the network once you're able to gain access to the network. And here is where the real fun starts because you're going to learn a number of powerful attacks that will allow you to intercept the connections in the network and capture everything sent in it, including usernames, passwords, URLs, chat messages, and so on. Not only that, but you'll also be able to modify data as it's being sent in the air, so you'll be able to control the requests, serve people fake updates, inject evil code into the pages that they load and so many other cool things. So everything in the third section will apply for both Wi-Fi and wired networks.
