Description
As this decade comes to a closure, we are looking at, what we like to call, an Industry 4.0. This era is expected to see radical changes in the way we work and live, due to huge leaps and advancements with technologies such as Blockchain and Quantum Computing. This calls for the new age workforce to be industry-ready, which essentially means an understanding of the core fields of Cybersecurity, Blockchain, and Quantum Computing is becoming imperative.
This book starts with a primer on the “Essentials of Cybersecurity”. This part allows the reader to get comfortable with the concepts of cybersecurity that are needed to gain a deeper understanding of the concepts to follow.
What will you learn
By the end of the book, you should be able to understand the gravity of the concepts involved in technologies like Blockchain and Cybersecurity, with an acute understanding of the areas, such as Quantum Computing, which affect the technologies. You will also know about the tools used in Smart Contract Auditing and Testing in Blockchain.
Who this book is for
This book is meant for everyone who wishes to build a career in blockchain and/or cybersecurity. The book doesn’t assume prior knowledge on any of the topics; hence a beginner from any diverse field might definitely give these technologies a try by reading this book. The book is divided into parts that take the reader seamlessly from beginner concepts to advanced practices prevalent in the industry. No prior programming experience is assumed either.
