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.

From the birth of the internet, every new technology had disrupted an existing one, whether it was email or the web, or even e-commerce. The internet is one of the strongest technologies and has been powerful enough to spread out ideas to impact and create illusions for reality.

TCP/IP was the first internet protocol suite built to standardize communication between similar networks; however, the OSI model was developed by the International Standard Organization (ISO) to provide a framework to standardize communication between systems, irrespective of vendors, models, and technologies. Organizations preferred both models for client/server communication because client/server networks tend to be much more reliable and stable in nature. It was important to have better control over what data customers were using...
