Python Ethical Hacking from Scratch

By: Fahad Ali Sarwar

Overview of this book

Penetration testing enables you to evaluate the security or strength of a computer system, network, or web application that an attacker can exploit. With this book, you'll understand why Python is one of the fastest-growing programming languages for penetration testing. You'll find out how to harness the power of Python and pentesting to enhance your system security. Developers working with Python will be able to put their knowledge and experience to work with this practical guide. Complete with step-by-step explanations of essential concepts and practical examples, this book takes a hands-on approach to help you build your own pentesting tools for testing the security level of systems and networks. You'll learn how to develop your own ethical hacking tools using Python and explore hacking techniques to exploit vulnerabilities in networks and systems. Finally, you'll be able to get remote access to target systems and networks using the tools you develop and modify as per your own requirements. By the end of this ethical hacking book, you'll have developed the skills needed for building cybersecurity tools and learned how to secure your systems by thinking like a hacker.

Components of a basic computer network

In this section, we will learn about the different components of a computer network. In computer network literature, you will often see the term node being used to represent a computer in a network. In networking domains, a specific nomenclature is used to identify particular devices in a network. We will look at these terms next.

Node

A node is usually a device that is connected to the central device. In a sense, it is a computer that takes part in a communication network. This works for simple and small networks, but as more and more devices get added to a network, different devices start taking up different roles, so we can only simplify a device's role in a network as a node up to a certain point. In qualifying scenarios, nodes can be your laptop, desktop PC, printer, tablet, phone, or any other network connected device.

Server

Servers are computers that hold some information that can be shared over the network to devices...
