Today, Artificial Intelligence (AI) and Machine Learning/ Deep Learning (ML/DL) have become the hottest areas in information technology. In our society, many intelligent devices rely on AI/ML/DL algorithms/tools for smart operations. Although AI/ML/DL algorithms and tools have been used in many internet applications and electronic devices, they are also vulnerable to various attacks and threats. AI parameters may be distorted by the internal attacker; the DL input samples may be polluted by adversaries; the ML model may be misled by changing the classification boundary, among many other attacks and threats. Such attacks can make AI products dangerous to use.
While this discussion focuses on security issues in AI/ML/DL-based systems (i.e., securing the intelligent systems themselves), AI/ML/DL models and algorithms can actually also be used for cyber security (i.e., the use of AI to achieve security).
Since AI/ML/DL security is a newly emergent field, many researchers and industry professionals cannot yet obtain a detailed, comprehensive understanding of this area. This book aims to provide a complete picture of the challenges and solutions to related security issues in various applications. It explains how different attacks can occur in advanced AI tools and the challenges of overcoming those attacks. Then, the book describes many sets of promising solutions to achieve AI security and privacy.

Vulnerability has traditionally been viewed through the lens of specific groups of people, such as ethnic minorities, children, the elderly, or people with disabilities. With the rise of digital media, our perceptions of vulnerable groups and individuals have been reshaped as new vulnerabilities and different vulnerable sub-groups of users, consumers, citizens, and data subjects emerge. Vulnerability and Data Protection Law not only depicts these problems but offers the reader a detailed investigation of the concept of data subjects and a reconceptualization of the notion of vulnerability within the General Data Protection Regulation. The regulation offers a forward-facing set of tools that-though largely underexplored-are essential in rebalancing power asymmetries and mitigating induced vulnerabilities in the age of artificial intelligence. Considering the new risks and potentialities of the digital market, the new awareness about cognitive weaknesses, and the new philosophical sensitivity about the condition of human vulnerability, the author looks for a more general and layered definition of the data subject's vulnerability that goes beyond traditional labels. In doing so, he seeks to promote a 'vulnerability-aware' interpretation of the GDPR. A heuristic analysis that re-interprets the whole GDPR, this work is essential for both scholars of data protection law and for policymakers looking to strengthen regulations and protect the data of vulnerable individuals.

This book explains the five pillars or battlefields of cybersecurity and how a Zero Trust approach can change the advantage on each battlefield. We have taken a deep dive into each of five battlefields where we have a decided disadvantage due to constitutional structure and moral behavioral guidelines, where we provide examples of how we got here, what we can do about it, why we got here, and how we can avoid these traps in the future. This is a unique viewpoint that has never been explored – the five battlefields include Economics, Technology, Information, Education, and Leadership – and how each has contributed to our current disadvantage on the global stage. We go on to discuss how Zero Trust can change the game to create an advantage for us going forward. The credibility of Zero Trust stems directly from the father of Zero Trust, John Kindervag, who says, “And now, Steve has written a new book on Zero Trust called Losing the Cybersecurity War: And What We Can Do to Stop It. It is undeniably the best Zero Trust book yet written. While other writers have focused on implementing Zero Trust from their perspectives, Steve focuses on why Zero Trust is so important on the modern cybersecurity battlefield. His concept of the five cyber battlefields is a great insight that will help us win the cyberwar. By weaving Zero Trust principles throughout these five concepts, Steve demonstrates how the ideas and efforts involved in building Zero Trust environments will lead to a profound shift in terrain advantage. No longer will attackers own the high ground. As defenders and protectors, we can leverage modern technology in a Zero Trust way to keep our data and assets safe from infiltration and exploitation.”

Balance the benefits of digital transformation with the associated risks with this guide to effectively managing cybersecurity as a strategic business issue. Important and cost-effective innovations can substantially increase cyber risk and the loss of intellectual property, corporate reputation and consumer confidence. Over the past several years, organizations around the world have increasingly come to appreciate the need to address cybersecurity issues from a business perspective, not just from a technical or risk angle. Cybersecurity for Business builds on a set of principles developed with international leaders from technology, government and the boardroom to lay out a clear roadmap of how to meet goals without creating undue cyber risk.This essential guide outlines the true nature of modern cyber risk, and how it can be assessed and managed using modern analytical tools to put cybersecurity in business terms. It then describes the roles and responsibilities each part of the organization has in implementing an effective enterprise-wide cyber risk management program, covering critical issues such as incident response, supply chain management and creating a culture of security. Bringing together a range of experts and senior leaders, this edited collection enables leaders and students to understand how to manage digital transformation and cybersecurity from a business perspective.

This book examines how internal and external security are blurring at the EU level, and the implications this has for EU security governance and the EU as a security actor. The EU claims that 'internal and external security are inseparable' and requires a more integrated approach. This book critically assesses this claim in relation to the threats facing the EU, its responses to them, and the practical and normative implications for EU security governance and actorness. It sets out a novel conceptual framework - the EU security continuum - to examine the ways and extent to which internal and external security are blurring along three axes: geographic, bureaucratic, and functional. This is done through an analysis of four key security issues, regional conflict, terrorism, organised crime, and cybersecurity. The book demonstrates that, to varying degrees, these security threats and/or responses do transcend boundaries. However, institutional turf wars and capability silos hamper the EU's integrated approach and, therefore, its management of transboundary security threats. Yet, the EU's pursuit of an integrated approach is reframing its claimed normative distinctiveness toward a more practical one, based on a transnational and multidimensional approach. Such a rearticulation, if implemented, would make the EU a genuinely transboundary security actor, properly structured and equipped to tackle the 21st century's internal-external security continuum. This book will be of much interest to students of European Security, EU politics, and international relations.

Cybersecurity Law Fundamentals is both a primer and a reference volume, with pointers to more in-depth resources. It organizes the disparate threads of cybersecurity law into a framework. It can be picked up and perused by generalists and newcomers to the field: the general counsel of a corporation whose area of expertise may be far from cybersecurity but who must have a basic understanding of regulatory requirements and of the legal risk the company will face when it suffers a breach; the policymaker interested in understanding the gaps in the law and filling them; the attorney seeking a career transition to a rapidly growing practice area; the journalist trying to contextualize a new executive order or legislative proposal. But it also serves the cybersecurity practitioner looking for a quick refresher or a citation.

Fuite de données personnelles, piratage massif, espionnage économique, infection de systèmes informatiques sensibles, propagation de « rançongiciels », usurpation d’identité, craintes vis-à-vis des paiements par carte bancaire : les questions relatives à la cybersécurité hantent l’actualité. Il est cependant difficile d’appréhender sereinement, à travers ce flux d’information continu et massif, la portée des problèmes et de leurs solutions. Car la question est difficile, hautement technique, à la croisée des mathématiques, de l’informatique et de l’électronique, ce qui la rend mystérieuse pour qui n’est pas spécialiste. Or, l’omniprésence des outils informatiques dans la vie quotidienne comme professionnelle, tous secteurs d’activités confondus, fait aujourd’hui de la cybersécurité un enjeu majeur qui nous concerne tous. La recherche vise à résoudre les défis qui permettront demain de garantir un monde plus sûr. Cet ouvrage fait le point sur treize d’entre eux et permet de dépister les fantasmes qui entourent la cybersécurité, en apportant un éclairage scientifique à destination des ingénieurs, chercheurs, décideurs et plus généralement de toute personne désireuse d’en apprendre davantage.

Même si l’intelligence artificielle a, dès sa naissance dans les années 1950, retenu toute l’attention des acteurs de la défense dans de nombreux pays du monde, ce n’est qu’une vingtaine d’années plus tard qu’elle rencontre un réel succès avec l’application des systèmes experts militaires. Aujourd’hui, l’intelligence artificielle participe pleinement à la transformation du cyberespace et à la militarisation de ce dernier.Cet ouvrage retrace et analyse le parcours réalisé par l’intelligence artificielle dans les domaines de la sécurité et de la défense dans le monde (États-Unis, Russie, Europe, Asie, etc.). À l’ère du cyberespace, de la cybersécurité et de la cyberdéfense, l’intelligence artificielle est mise au service de nouvelles doctrines et stratégies militaires. En raison de leurs potentiels effets et de la difficulté de leur maîtrise, les utilisations envisagées soulèvent cependant de très nombreuses questions aux niveaux tactiques, opérationnels, stratégiques et politiques.
