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.

Emerging security challenges


Every organization has to be a part of this never-ending race against cyber attackers. If you fail to keep yourself ahead of your adversaries, you are likely become the victim of attacks. In the coming years, defenders have to prepare themselves for some of the emerging security challenges and threats. These are as follows:

  • Slow security adaptation: Unlike networking and cloud transformation, cyber security solutions are not evolving at the expected rate. The traditional network segmentation has been replaced with a simplified and flat architecture, removing lots of network complexity. However, security solutions still use the traditional zone-based approach to mitigate threats.
  • Human error: As per the IBM Security service report, more than 95% of investigated cyber incidents occurred due to human errors, such as system misconfiguration and insufficient patch management.
  • Third-party vendor security risk: In the world of interconnected businesses, organizations have to let other organizations store and use their information for better business operations, but this can also lead to a bigger risk. If a third party gets compromised, the organization is at risk of losing business data. Most supply chain attacks use sophisticated attack vectors that manage to bypass existing security systems.
