Preface

This book is dedicated to the use of Kali Linux to perform penetration tests on networks, systems, and applications. A penetration test simulates an attack against a network or a system by a malicious outsider or insider. Unlike a vulnerability assessment, penetration testing is designed to include the exploitation phase. Therefore, it proves that the exploit is present, and that it is accompanied by the very real risk of being compromised if not acted upon.

Throughout this book, we will refer to penetration testers, attackers, and hackers interchangeably, as they use the same techniques and tools to assess the security of networks and data systems. The only difference between them is their end objective–a secure data network, or a data breach.

In short, this book will take you through penetration testing with a number of proven techniques to defeat the latest defenses on a network using Kali Linux, from selecting the most effective tools, to rapidly compromising network security, to highlighting the techniques used to avoid detection.
