Modern Cryptography for Cybersecurity Professionals

By: Lisa Bock

Overview of this book

In today's world, it is important to have confidence in your data storage and transmission strategy. Cryptography can provide you with this confidentiality, integrity, authentication, and non-repudiation. But are you aware of just what exactly is involved in using cryptographic techniques? Modern Cryptography for Cybersecurity Professionals helps you to gain a better understanding of the cryptographic elements necessary to secure your data. The book begins by helping you to understand why we need to secure data and how encryption can provide protection, whether it be in motion or at rest. You'll then delve into symmetric and asymmetric encryption and discover how a hash is used. As you advance, you'll see how the public key infrastructure (PKI) and certificates build trust between parties, so that we can confidently encrypt and exchange data. Finally, you'll explore the practical applications of cryptographic techniques, including passwords, email, and blockchain technology, along with securely transmitting data using a virtual private network (VPN). By the end of this cryptography book, you'll have gained a solid understanding of cryptographic techniques and terms, learned how symmetric and asymmetric encryption and hashed are used, and recognized the importance of key management and the PKI.

Chapter 3: Evaluating Network Attacks

In today's information superhighway, there is a voluminous amount of data housed on our systems, and traveling over networks and the internet. Because of this, we must face the fact that it's not a matter of whether there will be an attack, it's a matter of when an attack will occur. The reality is that not all attacks are the same. In this chapter, we'll outline how a network can fall victim to either a passive or active attack, and we'll review examples of both. We'll see that while a passive attack may not seem serious, it can be a precursor to an active attack.

In addition, we'll see that there are many attack vectors that, if not properly protected, can lead to data exfiltration or exposure of confidential information. You'll learn that, today, data is in many places and is growing at an exponential rate, and with this growth comes a greater need to protect the data. Finally, you'll get a better...
