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.

Countermeasures for cryptography

You know me, I don't want to leave you all panicking that all is lost! There are some countermeasures that we can take to mitigate the attacks that might come our way. Let's talk about some of these countermeasures.

EC-Council lists 12 countermeasures to use:

  1. The first one is when it comes to accessing the cryptography keys, that access should only be given to users directly, as well as applications.
  2. You should also make sure you have an intrusion detection system (IDS) that's been deployed, and you are monitoring the exchange and access of those keys, so you've got a log somewhere of what happened and when. This is just in case you must go back and take a look at those logs because something got compromised.
  3. The other thing you're going to want to do is that if you plan on storing the encryption key on a system or on a drive, you need to use passphrases and passwords.
