Cybersecurity

An accessible guide to cybersecurity for the everyday user, covering cryptography and public key infrastructure, malware, blockchain, and other topics. It seems that everything we touch is connected to the internet, from mobile phones and wearable technology to home appliances and cyber assistants. The more connected our computer systems, the more exposed they are to cyber attacks--attempts to steal data, corrupt software, disrupt operations, and even physically damage hardware and network infrastructures. In this volume of the MIT Press Essential Knowledge series, cybersecurity expert Duane Wilson offers an accessible guide to cybersecurity issues for everyday users, describing risks associated with internet use, modern methods of defense against cyber attacks, and general principles for safer internet use. Wilson describes the principles that underlie all cybersecurity defense: confidentiality, integrity, availability, authentication, authorization, and non-repudiation (validating the source of information). He explains that confidentiality is accomplished by cryptography; examines the different layers of defense; analyzes cyber risks, threats, and vulnerabilities; and breaks down the cyber kill chain and the many forms of malware. He reviews some online applications of cybersecurity, including end-to-end security protection, secure ecommerce transactions, smart devices with built-in protections, and blockchain technology. Finally, Wilson considers the future of cybersecurity, discussing the continuing evolution of cyber defenses as well as research that may alter the overall threat landscape.

Cybersecurity can be defined as a set of methods used to safeguard the integrity of data, networks, and programs from damage, attacks, and unauthorized access. Security can be classified into two sub-categories: physical security and cybersecurity. Both of these securities are essential to protect the computerized systems from unauthorized accessl; therefore, most of the organizations focus on fortifying both aspects of security. Information security (a subset of cybersecurity) focusses on maintaining the confidentiality, integrity, and availability of the personal or professional data. The implementation of cybersecurity and information security helps in preventing data breaches, identity thefts, and cyber-attacks.This book offers an overview of essential components and methods of cybersecurity. The first three chapters of the book contain fundamental knowledge of cybersecurity while the later chapters focus on different methods of cybersecurity. The knowledge of the internet and the underlying phenomena occurring in the cyber world is essential to understand the basics of cybersecurity. Readers of this book will learn about the essential concepts of cybersecurity. These are realities that constitute the basis of our knowledge of cybersecurity. The information gained from this book will help the reader understand the requirement to improve cybersecurity applications. Implementation of cybersecurity principles is essential to safeguard our systems connected to the cyber world.

This book gives a complete introduction to cybersecurity and its many subdomains. It’s unique by covering both technical and governance aspects of cybersecurity and is easy to read with 150 full color figures. There are also exercises and study cases at the end of each chapter, with additional material on the book's website. The numerous high-profile cyberattacks being reported in the press clearly show that cyberthreats cause serious business risks. For this reason, cybersecurity has become a critical concern for global politics, national security, organizations as well for individual citizens. While cybersecurity has traditionally been a technological discipline, the field has grown so large and complex that proper governance of cybersecurity is needed. The primary audience for this book is advanced level students in computer science focusing on cybersecurity and cyber risk governance. The digital transformation of society also makes cybersecurity relevant in many other disciplines, hence this book is a useful resource for other disciplines, such as law, business management and political science. Additionally, this book is for anyone in the private or public sector, who wants to acquire or update their knowledge about cybersecurity both from a technological and governance perspective.
