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.

The security ecosystem 


Thousands of security bodies and security researchers work round the clock to innovate and develop an effective solution to address emerging threats. Organizations spend millions of dollars every year to enhance their security posture and tools. They keep researching zero-day vulnerabilities, building artificial neural networks (ANNs) for endpoint protection, making machine learning models for new threats, building an effective cybersecurity incident response process and awareness program, and so on.

There are four main categories of cyberattack prevention strategies:

  • Reduce the attack surface: Most organizations have a regular process to conduct vulnerability scanning both externally and internally for unwanted application ports, file extension information, and platform information. This continuous process of security threat evaluation helps them to determine answers to the following questions:
    • What are we doing different? (technology, process, application, people,...
