Blockchain in cybersecurity realm: An overview

Abstract

Cybersecurity is a pressing need for governments, businesses, and individuals, which is compounded by the fast-pace technological changes and changing cyberthreat landscape. A large number of solutions have been proposed to address the changing security requirements, and one of such solutions is based on blockchain. Blockchain is a promising infrastructural technology, with potential to be leveraged in different aspects of cybersecurity. For example, blockchain characteristics such as decentralization, verifiability and immutability can facilitate one to achieve authenticity, reliability and integrity of data. Yet, little is known about factors related to the adoption decisions and how it can systemically be put into use to remedy current security’s issues in the digital world. In order to advance the body of practical and theoretical knowledge, this book seeks to provide a sample of cutting-edge research from both academia and industry to perceive blockchain cybersecurity and its current solutions in a clearer context and pave the way for the future.
