Nowadays, in Cyberspace there is a burst of information that everyone has access. However, apart from the advantages the Internet offers, it also hides numerous dangers for both people and nations. Cyberspace has a dark side, including terrorism, bullying, and other types of violence. Cyberwarfare is a kind of virtual war that causes the same destruction that a physical war would also do. A hybrid threat is an umbrella term, encompassing a wide variety of existing adverse circumstances and actions, such as terrorism, migration, piracy, corruption, ethnic conflict etc and is not exclusively a tool of asymmetric or non-state actors, but can be applied by state and non-state actors alike. ‘Cyber-conflict’ and ‘cyber-war’ serve as examples of the use of new technologies within the scope of hybrid threats. Cyber-war basically refers to a sustained computer-based cyber-attack by a state against the IT infrastructure of a target state. On the other hand cyber-security is a major factor that shapes productivity and efficiency of the modern industry in both technical and economic terms. The book discusses and analyses current posture of cyberterrorism, cyberwarfare, and hybrid threats, sector specific cyber-attacks that have the form of cyberterrorism and presents the recent actions that EU, USA and other Nations have taken in order to strengthen their systems against such attacks. There has never been a higher risk of a major catastrophe as a result of the rise in offensive cyber activity, particularly the possibility of cyber-physical strikes against critical services. Recent cyber-attacks against critical infrastructures along with the continuous migration crisis have been the main driving forces that led to the decision to publish this book.

The threat landscape is evolving with tremendous speed. We are facing an extremely fast-growing attack surface with a diversity of attack vectors, a clear asymmetry between attackers and defenders, billions of connected IoT devices, mostly reactive detection and mitigation approaches, and finally big data challenges. The clear asymmetry of attacks and the enormous amount of data are additional arguments to make it necessary to rethink cybersecurity approaches in terms of reducing the attack surface, to make the attack surface dynamic, to automate the detection, risk assessment, and mitigation, and to investigate the prediction and prevention of attacks with the utilization of emerging technologies like blockchain, artificial intelligence and machine learning. This book contains eleven chapters dealing with different Cybersecurity Issues in Emerging Technologies. The issues that are discussed and analyzed include smart connected cars, unmanned ships, 5G/6G connectivity, blockchain, agile incident response, hardware assisted security, ransomware attacks, hybrid threats and cyber skills gap. Both theoretical analysis and experimental evaluation of state-of-the-art techniques are presented and discussed. Prospective readers can be benefitted in understanding the future implications of novel technologies and proposed security solutions and techniques. Graduate and postgraduate students, research scholars, academics, cybersecurity professionals, and business leaders will find this book useful, which is planned to enlighten both beginners and experienced readers.
