Hands-On Cybersecurity with Blockchain

By: Rajneesh Gupta

Overview of this book

Blockchain technology is being welcomed as one of the most revolutionary and impactful innovations of today. Blockchain technology was first identified in the world’s most popular digital currency, Bitcoin, but has now changed the outlook of several organizations and empowered them to use it even for storage and transfer of value. This book will start by introducing you to the common cyberthreat landscape and common attacks such as malware, phishing, insider threats, and DDoS. The next set of chapters will help you to understand the workings of Blockchain technology, Ethereum and Hyperledger architecture and how they fit into the cybersecurity ecosystem. These chapters will also help you to write your first distributed application on Ethereum Blockchain and the Hyperledger Fabric framework. Later, you will learn about the security triad and its adaptation with Blockchain. The last set of chapters will take you through the core concepts of cybersecurity, such as DDoS protection, PKI-based identity, 2FA, and DNS security. You will learn how Blockchain plays a crucial role in transforming cybersecurity solutions. Toward the end of the book, you will also encounter some real-world deployment examples of Blockchain in security cases, and also understand the short-term challenges and future of cybersecurity with Blockchain.

Chapter 9. Deploying Blockchain-Based DDoS Protection

The internet is growing dramatically in both the number of users and applications, and their respective bandwidth. Over the past few years, a new variant of user has entered the world of the internet, commonly known as a smart device. In its simplest form, it can be a refrigerator, an AC unit, or a microwave, while it can be as complex as a drone or automated vehicle. These smart devices are also referred to as Internet of Things (IoT) devices, monitoring the functionality and operations of connected utilities. Despite of enough use cases, attackers are making use of them to launch some massive cyber attacks called distributed denial-of-service (DDoS) attacks. In this chapter, you will learn about DDoS attacks and how blockchain can be more effective at defending organizations from such massive attack operations.

In this chapter, we will cover the following topics:

  • DDoS attacks
  • Types of DDoS attacks
  • Challenges with current DDoS protection...
