Certified Ethical Hacker (CEH) v12 312-50 Exam Guide

By: Dale Meredith

Overview of this book

With cyber threats continually evolving, understanding the trends and using the tools deployed by attackers to determine vulnerabilities in your system can help secure your applications, networks, and devices. To outmatch attacks, developing an attacker's mindset is a necessary skill, which you can hone with the help of this cybersecurity book. This study guide takes a step-by-step approach to helping you cover all the exam objectives using plenty of examples and hands-on activities. You'll start by gaining insights into the different elements of InfoSec and a thorough understanding of ethical hacking terms and concepts. You'll then learn about various vectors, including network-based vectors, software-based vectors, mobile devices, wireless networks, and IoT devices. The book also explores attacks on emerging technologies such as the cloud, IoT, web apps, and servers and examines prominent tools and techniques used by hackers. Finally, you'll be ready to take mock tests, which will help you test your understanding of all the topics covered in the book. By the end of this book, you'll have obtained the information necessary to take the 312-50 exam and become a CEH v11 certified ethical hacker.

What is sniffing?

Using sniffing tools, an attacker can monitor and capture packets passing through a network and spy on what is going on with internet activity.

Let's talk more specifically about what sniffing is and how to leverage it in an attack.

There are two types of wiretaps out there, as outlined here:

  • Active wiretapping allows an attacker to manipulate and force themselves into the middle using a Man-in-the-Middle (MITM) attack, which allows the attacker to record and monitor traffic. As an active channel, it can allow the attacker to change the data flowing through or inject information. When it comes to ethical hacking, active means we're going to do something extremely aggressive by forcing a communication. You can see a depiction of a MITM attack in the following diagram:

  • Passive wiretapping allows an attacker to eavesdrop or listen into conversations—nothing malicious; it...
