- The zero-trust approach requires complete visibility and control over the network. This takes several human hours to perform the assessment and internal network audit. It is critical to understand the concept of network avenues, vulnerabilities, third-party channels, business partner networks, DMZ, and so on, before a zero-trust approach can be considered. Most organizations tend to use default settings with most of their applications and network devices, which can also be a problem in deploying an efficient zero-trust approach.
- The breach-assume approach helps organizations to prepare for data-breach conditions so that a better cyber defense program can be planned. The breach-assume mindset requires continuous network and application monitoring with an added layer of incident response planning. It is important to segregate normal traffic and abnormal traffic, applying an appropriate policy and response to each dataset. This entire process must be undertaken carefully and precisely, as a small mistake can disturb the whole approach.
- The internet was never built to be used for financial systems and critical asset transfers. However, since becoming highly dependent on the internet, organizations are now continually adding new security layers to defend critical infrastructure. Almost all business applications are running over client-server frameworks to support existing TCP/IP internet stacks; moving from a centralized database needs a high degree of interoperability support and industry acceptance.

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.
