This SpringerBrief  contains eight chapters and presents an overview of the evolution of the Moroccan Cybersecurity Strategy. It also draws attention to the development of cybersecurity in Morocco and to ensure national security in the context of the current and developing information confrontation in the international community. However, it cannot promise to provide an in-depth examination. The issue of cybersecurity is simply too wide-ranging for our purposes. This acknowledgment is meant to encourage more detailed research into the broader topics covered in this brief to better inform current approaches to national cybersecurity performance evaluation.This SpringerBrief targets researchers interested in exploring and understanding Morocco and its efforts in implementing its national cybersecurity strategy. This brief is also a relevant reference for diplomats, executives, CISOs, cybersecurity professionals and engineers working in this related field.

In the world as we know it, you can be attacked both physically and virtually. For today's organisations, which rely so heavily on technology - particularly the Internet - to do business, the latter is the far more threatening of the two. The cyber threat landscape is complex and constantly changing. For every vulnerability fixed, another pops up, ripe for exploitation.This book is a comprehensive cyber security implementation manual which gives practical guidance on the individual activities identified in the IT Governance Cyber Resilience Framework (CRF) that can help organisations become cyber resilient and combat the cyber threat landscape.Suitable for senior directors (CEO, CISO, CIO), compliance managers, privacy managers, IT managers, security analysts and others, the book is divided into six parts:Part 1: Introduction. The world of cyber security and the approach taken in this book.Part 2: Threats and vulnerabilities. A discussion of a range of threats organisations face, organised by threat category, to help you understand what you are defending yourself against before you start thinking about your actual defences.Part 3: The CRF processes. Detailed discussions of each of the 24 CRF processes, explaining a wide range of security areas by process category and offering guidance on how to implement each.Part 4: Eight steps to implementing cyber security. Our eight-step approach to implementing the cyber security processes you need and maintaining them.Part 5: Reference frameworks. An explanation of how standards and frameworks work, along with their benefits.

Die Kunst des Cyberkrieges greift die strategischen und taktischen Vorgehensweisen für Angriff und Verteidigung im digitalen Zeitalter auf. Dazu bedient sich der Autor historischer Konflikte (von Sun Tsu bis Carl von Clausewitz) und deren Ausgängen, um aufzuzeigen, dass es ungeachtet der veränderten Bedingungen wie Zeit, Ort, Mittel und Ressourcen ¿ nicht aber der physikalischen Gesetze ¿ möglich ist, von früheren Aktionen und deren Reaktionen zu lernen.Der Autor möchte mit diesem Buch zeigen, dass wir in Wirklichkeit nur alte Methoden in unser jetziges Zeitalter transferiert, aber dabei vergessen haben, deren Gründe und Auswirkungen und natürlich die daraus resultierenden Lehren mit zu übersetzen. Denn wie schon vor tausenden von Jahren sind und bleiben die Gründe für menschengeschaffene Konflikte immer dieselben: Reichtum, Ruhm, Macht, Ehre oder Lust. Kann man aus der Geschichte etwas für heutige und zukünftige (Cyber-)Kriege lernen?

Data privacy technologies are essential for implementing information systems with privacy by design.Privacy technologies clearly are needed for ensuring that data does not lead to disclosure, but also that statistics or even data-driven machine learning models do not lead to disclosure.  For example, can a deep-learning model be attacked to discover that sensitive data has been used for its training?  This accessible textbook presents privacy models, computational definitions of privacy, and methods to implement them. Additionally, the book explains and gives plentiful examples of how to implement-among other models-differential privacy, k-anonymity, and secure multiparty computation.Topics and features:Provides integrated presentation of data privacy (including tools from statistical disclosure control, privacy-preserving data mining, and privacy for communications)Discusses privacy requirements and tools for different types of scenarios, including privacy for data, for computations, and for usersOffers characterization of privacy models, comparing their differences, advantages, and disadvantagesDescribes some of the most relevant algorithms to implement privacy modelsIncludes examples of data protection mechanismsThis unique textbook/guide contains numerous examples and succinctly and comprehensively gathers the relevant information. As such, it will be eminently suitable for undergraduate and graduate students interested in data privacy, as well as professionals wanting a concise overview.Vicenc Torra is Professor with the Department of Computing Science at Umea University, Umea, Sweden.

This book explores the emergent concept of 'human security' within the political context of COVID-19 Chinese politics. For decades, Western nations have used 'human rights' as a rubric with which to scold Chinese leaders, betraying a fundamental unwillingness to accept diversity of governance systems. As COVID-19 has demonstrated, different governance systems yield different outcomes-the freedom of circulation, speech and movement in Western democracies yielding one, and use of surveillance, lockdowns, and private-public collaboration in China and Asian societies such as Korea and Singapore yielding another. Chinese political scientists have become fixated on the notion of 'human security,' a utilitarian concept which insists on the importance of protecting and extending human life via health care, technology, and a wide range of other systems-sometimes, in ways which contradict Western notions of human rights, even as they demonstrably achieve superior outcomes for the humans involved. Being the first English language book to explore these issues, this book aims to generate a sustained theoretical relevance in the aftermath of the crisis which is likely to have lasting effects on how people live and will be of note for political scientists, China scholars, and economists.

"This is a powerful model of engaged, twenty-first century social criticism. Writing in the tradition of Jane Jacobs, Margaret Mead, and Rebecca Solnit, Jessa Lingel is a formidable new critical voice in America."--Siva Vaidhyanathan, author of Antisocial Media and The Googlization of Everything "The Gentrification of the Internet deftly dismantles romanticized notions of Big Tech, helping readers understand the internet as a site of increasing isolation, commodification, surveillance, and displacement. This readable and accessible book will definitely be required reading for all my courses." --Clemencia Rodríguez, Professor of Media Studies, Temple University "Jessa Lingel's book persuasively demonstrates that gentrification and its consequences in terms of displacement, isolation and commercialization has migrated from the realm of the urban economy to the internet. A revealing account of the way the digital world has transitioned from a space for DIY countercultures to a playground for the corporate oligarchy."--Paolo Gerbaudo, Director of the Centre for Digital Culture at King's College London

This SpringerBrief presents a brief introduction to probabilistic risk assessment (PRA), followed by a discussion of abnormal event detection techniques in industrial control systems (ICS). It also provides an introduction to the use of game theory for the development of cyber-attack response models and a discussion on the experimental testbeds used for ICS cyber security research. The probabilistic risk assessment framework used by the nuclear industry provides a valid framework to understand the impacts of cyber-attacks in the physical world. An introduction to the PRA techniques such as fault trees, and event trees is provided along with a discussion on different levels of PRA and the application of PRA techniques in the context of cybersecurity. A discussion on machine learning based fault detection and diagnosis (FDD) methods and cyber-attack detection methods for industrial control systems are introduced in this book as well.A dynamic Bayesian networks based method that can be used to detect an abnormal event and classify it as either a component fault induced safety event or a cyber-attack is discussed. An introduction to the stochastic game formulation of the attacker-defender interaction in the context of cyber-attacks on industrial control systems to compute optimal response strategies is presented. Besides supporting cyber-attack response, the analysis based on the game model also supports the behavioral study of the defender and the attacker during a cyber-attack, and the results can then be used to analyze the risk to the system caused by a cyber-attack. A brief review of the current state of experimental testbeds used in ICS cybersecurity research and a comparison of the structures of various testbeds and the attack scenarios supported by those testbeds is included. A description of a testbed for nuclear power applications, followed by a discussion on the design of experiments that can be carried out on the testbed and the associated results is covered as well.This SpringerBrief  is a useful resource tool for researchers working in the areas of cyber security for industrial control systems, energy systems and cyber physical systems. Advanced-level students that study these topics will also find this SpringerBrief useful as a study guide.
