Hands-On Cybersecurity with Blockchain

▶Book Description
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.

▶What this book covers
⦁ Chapter 1, Cyber Threat Landscape and Security Challenges, covers the emerging global cyber threat landscape, what is making threats stronger and more sophisticated, and the defender perspective, including governments, International Security Alliance (ISA), and industry alliances, corporations, executives, Chief Security Officers (CSO), and security analysts.

⦁ Chapter 2, Security Must Evolve, describes some serious and urgent changes in the security mindset, such as the zero-trust approach, breach acceptance, and changes in the security foundation.

⦁ Chapter 3, Introducing Blockchain and Ethereum, describes blockchain from its birth and its continuous adaption among various industries and verticals. We will also get to know how organizations are using blockchain to solve their problems.

⦁ Chapter 4, Hyperledger –. Blockchain for Businesses, introduces you to the Hyperledger project, with its open source collaboration and develops a cross-industry blockchain technologies. It also provides the demonstration and deployment of dApp with Hyperledger peers.

⦁ Chapter 5, Blockchain on the CIA Security Triad, explains that any security measures are designed to protect one or more facets of the CIA triad, and therefore, it's a smart way to adapt blockchain in the underlying security foundation, such as enterprise key and certificate management, encryption, and access control.

⦁ Chapter 6, Deploying PKI-Based Identity with Blockchain, covers the real-world deployment of Blockchain in security cases with current state review, protocol implementation, architecture, structure, and API client integration.

⦁ Chapter 7, Two-Factor Authentication with Blockchain, contains insights into the components and workings of two-factor authentication. At the end, we will get to see how a decentralized two-factor authentication system can be achieved with an Ethereum blockchain.

⦁ Chapter 8, Blockchain-Based DNS Security Platform, discusses existing DNS infrastructure, challenges, and how blockchain help to build a more robust and secure decentralized DNS infrastructure.

⦁ Chapter 9, Deploying Blockchain-Based DDoS Protection, covers the impact of a DDoS attack, anatomy of a DDoS attack, challenges with existing DDoS protection solution and how an Ethereum blockchain can transform your DDoS protection platform.

⦁ Chapter 10, Facts about Blockchain and Cyber Security, covers some potential challenges with the blockchain system, such as node theft, the availability of distributed nodes, malicious code injection into a distributed ledger, reputational risk, target reconnaissance, and bypassing the offboarding and onboarding procedure.
