"Vaccine research patent details stolen by hackers""Filmstar blackmailed after criminals access photos on smartphone""Elderly widow has Internet bank account emptied by fraudsters""All computers at local hospital paralysed by computer virus""Government 'cannot find' documents stored on confidential database""Smart TVs can spy on you at home""Man arrested for having child pornography on his laptop 'didn't know how it got there'"Headlines like these reflect one of the dangers of modern life, where electronic communication between computers, smartphones and other electronic devices forms the basis for innumerable social, commercialand administrative activities.The aim of cybersecurity is to prevent such undesirable events from happening. This book gives a gentle introduction to what this involves, by answering questions such as: What should one look out for? How do failures of cybersecurity arise? And last but not least, why is perfect cybersecurity so hard to achieve?

This book provides an introduction to the basic ideas involved in cybersecurity, whose principal aim is protection of IT systems against unwanted behaviour mediated by the networks which connect them. Due to the widespread use of the Internet in modern society for activities ranging from social networking and entertainment to distribution of utilities and public administration, failures of cybersecurity can threaten almost all aspects of life today.Cybersecurity is a necessity in the modern world, where computers and other electronic devices communicate via networks, and breakdowns in cybersecurity cost society many resources.The aims of cybersecurity are quite simple: data must not be read, modified, deleted or made unavailable by persons who are not allowed to. To meet this major challenge successfully in the digitally interconnected world, one needs to master numerous disciplines because modern IT systems contain software, cryptographic modules, computing units, networks, and human users--all of which can influence the success or failure in the effort.Topics and features: Introduces readers to the main components of a modern IT system: basic hardware, networks, operating system, and network-based applicationsContains numerous theoretical and practical exercises to illustrate important topicsDiscusses protective mechanisms commonly used to ensure cybersecurity and how effective they areDiscusses the use of cryptography for achieving security in IT systemsExplains how to plan for protecting IT systems based on analysing the risk of various forms of failureIllustrates how human users may affect system security and ways of improving their behaviourDiscusses what to do if a security failure takes placePresents important legal concepts relevant for cybersecurity, including the concept of cybercrimeThis accessible, clear textbook is intended especially for students starting a relevant course in computer science or engineering, as well as for professionals looking for a general introduction to the topic.Dr. Robin Sharp is an emeritus professor in the Cybersecurity Section at DTU Compute, the Dept. of Applied Mathematics and Computer Science at the Technical University of Denmark (DTU).
