Zero Trust Networks: Building Secure Systems in Untrusted Networks
by Doug Barth Evan GilmanThe perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it.The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility.Understand how perimeter-based defenses have evolved to become the broken model we use todayExplore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty)Get example configuration for open source tools that you can use to build a zero trust networkLearn how to migrate from a perimeter-based network to a zero trust network in production
Zero Trust Networks
by Razi Rais Christina Morillo Evan Gilman Doug BarthThis practical book provides a detailed explanation of the zero trust security model. Zero trust is a security paradigm shift that eliminates the concept of traditional perimeter-based security and requires you to "always assume breach" and "never trust but always verify." The updated edition offers more scenarios, real-world examples, and in-depth explanations of key concepts to help you fully comprehend the zero trust security architecture.Examine fundamental concepts of zero trust security model, including trust engine, policy engine, and context aware agentsUnderstand how this model embeds security within the system's operation, with guided scenarios at the end of each chapterMigrate from a perimeter-based network to a zero trust network in productionExplore case studies that provide insights into organizations' zero trust journeysLearn about the various zero trust architectures, standards, and frameworks developed by NIST, CISA, DoD, and others

Zero Trust Security: An Enterprise Guide
by Jason Garbis Jerry W. ChapmanUnderstand how Zero Trust security can and should integrate into your organization. This book covers the complexity of enterprise environments and provides the realistic guidance and requirements your security team needs to successfully plan and execute a journey to Zero Trust while getting more value from your existing enterprise security architecture. After reading this book, you will be ready to design a credible and defensible Zero Trust security architecture for your organization and implement a step-wise journey that delivers significantly improved security and streamlined operations.Zero Trust security has become a major industry trend, and yet there still is uncertainty about what it means. Zero Trust is about fundamentally changing the underlying philosophy and approach to enterprise security—moving from outdated and demonstrably ineffective perimeter-centric approaches to a dynamic, identity-centric, and policy-based approach.Making this type of shift can be challenging. Your organization has already deployed and operationalized enterprise security assets such as Directories, IAM systems, IDS/IPS, and SIEM, and changing things can be difficult. Zero Trust Security uniquely covers the breadth of enterprise security and IT architectures, providing substantive architectural guidance and technical analysis with the goal of accelerating your organization‘s journey to Zero Trust. What You Will Learn Understand Zero Trust security principles and why it is critical to adopt themSee the security and operational benefits of Zero TrustMake informed decisions about where, when, and how to apply Zero Trust security architecturesDiscover how the journey to Zero Trust will impact your enterprise and security architectureBe ready to plan your journey toward Zero Trust, while identifying projects that can deliver immediate security benefits for your organization Who This Book Is ForSecurity leaders, architects, and practitioners plus CISOs, enterprise security architects, security engineers, network security architects, solution architects, and Zero Trust strategists
Zeroing Neural Networks: Finite-time Convergence Design, Analysis and Applications
by Lin Xiao Lei JiaZeroing Neural Networks Describes the theoretical and practical aspects of finite-time ZNN methods for solving an array of computational problems Zeroing Neural Networks (ZNN) have become essential tools for solving discretized sensor-driven time-varying matrix problems in engineering, control theory, and on-chip applications for robots. Building on the original ZNN model, finite-time zeroing neural networks (FTZNN) enable efficient, accurate, and predictive real-time computations. Setting up discretized FTZNN algorithms for different time-varying matrix problems requires distinct steps. Zeroing Neural Networks provides in-depth information on the finite-time convergence of ZNN models in solving computational problems. Divided into eight parts, this comprehensive resource covers modeling methods, theoretical analysis, computer simulations, nonlinear activation functions, and more. Each part focuses on a specific type of time-varying computational problem, such as the application of FTZNN to the Lyapunov equation, linear matrix equation, and matrix inversion. Throughout the book, tables explain the performance of different models, while numerous illustrative examples clarify the advantages of each FTZNN method. In addition, the book: Describes how to design, analyze, and apply FTZNN models for solving computational problems Presents multiple FTZNN models for solving time-varying computational problems Details the noise-tolerance of FTZNN models to maximize the adaptability of FTZNN models to complex environments Includes an introduction, problem description, design scheme, theoretical analysis, illustrative verification, application, and summary in every chapter Zeroing Neural Networks: Finite-time Convergence Design, Analysis and Applications is an essential resource for scientists, researchers, academic lecturers, and postgraduates in the field, as well as a valuable reference for engineers and other practitioners working in neurocomputing and intelligent control.

Zhang Functions and Various Models
by Yunong Zhang Dongsheng GuoThis book focuses on solving different types of time-varying problems. It presents various Zhang dynamics (ZD) models by defining various Zhang functions (ZFs) in real and complex domains. It then provides theoretical analyses of such ZD models and illustrates their results. It also uses simulations to substantiate their efficacy and show the feasibility of the presented ZD approach (i. e. , different ZFs leading to different ZD models), which is further applied to the repetitive motion planning (RMP) of redundant robots, showing its application potential.
Zhang Time Discretization (ZTD) Formulas and Applications
by Yunong Zhang Jinjin GuoThis book aims to solve the discrete implementation problems of continuous-time neural network models while improving the performance of neural networks by using various Zhang Time Discretization (ZTD) formulas.The authors summarize and present the systematic derivations and complete research of ZTD formulas from special 3S-ZTD formulas to general NS-ZTD formulas. These finally lead to their proposed discrete-time Zhang neural network (DTZNN) algorithms, which are more efficient, accurate, and elegant. This book will open the door to scientific and engineering applications of ZTD formulas and neural networks, and will be a major inspiration for studies in neural network modeling, numerical algorithm design, prediction, and robot manipulator control.The book will benefit engineers, senior undergraduates, graduate students, and researchers in the fields of neural networks, computer mathematics, computer science, artificial intelligence, numerical algorithms, optimization, robotics, and simulation modeling.
The Zimbabwean Crisis after Mugabe: Multidisciplinary Perspectives (Routledge Contemporary Africa)
by Tendai MangenaThis book examines the ways in which political discourses of crisis and ‘newness’ are (re)produced, circulated, naturalised, received and contested in Post-Mugabe Zimbabwe. Going beyond the ordinariness of conventional political, human and social science methods, the book offers new and engaging multi-disciplinary approaches that treat discourse and language as important sites to encounter the politics of contested representations of the Zimbabwean crisis in the wake of the 2017 coup. The book centres discourse on new approaches to contestations around the discursive framing of various aspects of the socio-economic and political crisis related to significant political changes in Zimbabwe post-2017. Contributors in this volume, most of whom experienced the complex transition first-hand, examine some of the ways in which language functions as a socio-cultural and political mechanism for creating imaginaries, circulating, defending and contesting conceptions, visions, perceptions and knowledges of the post-Mugabe turn in the Zimbabwean crisis and its management by the "New Dispensation". This book will be of interest to scholars of African studies, postcolonial studies, language/discourse studies, African politics and culture.

ZK Developer's Guide
by Jurgen Schumacher Markus StäubleZK is an open-source web development framework that enables web applications to have the rich user experiences and low development costs that desktop applications have had for years. ZK includes an Ajax-based event-driven engine, rich sets of XML User Interface Language (XUL) and XHTML components, and a markup language. The ZK rich client framework takes the so-called server-centric approach: the content synchronization of components and the event pipelining between clients and servers are automatically done by the engine and Ajax plumbing codes are completely transparent to web application developers. Therefore, the end users get rich user interfaces with similar engaged interactivity and responsiveness to that of desktop applications, while for programmers, development remains similar in simplicity to that of desktop applications. This book is a Developer's Guide that steps you through the ZK framework with examples. It starts with installing and configuring ZK and takes you on to integrate it with other frameworks. By the time you are through the book you will be able to build an application on your own.

Zucked: Waking Up to the Facebook Catastrophe
by Roger McNameeThe story of how a noted tech venture capitalist, an early mentor to Mark Zuckerberg and investor in his company, woke up to the serious damage Facebook was doing to our society and set out to try to stop it. <P><P>If you had told Roger McNamee even three years ago that he would soon be devoting himself to stopping Facebook from destroying our democracy, he would have howled with laughter. He had mentored many tech leaders in his illustrious career as an investor, but few things had made him prouder, or been better for his fund's bottom line, than his early service to Mark Zuckerberg. Still a large shareholder in Facebook, he had every good reason to stay on the bright side. Until he simply couldn't. <P><P>ZUCKED is McNamee's intimate reckoning with the catastrophic failure of the head of one of the world's most powerful companies to face up to the damage he is doing. It's a story that begins with a series of rude awakenings. First there is the author's dawning realization that the platform is being manipulated by some very bad actors. <P><P>Then there is the even more unsettling realization that Zuckerberg and Sheryl Sandberg are unable or unwilling to share his concerns, polite as they may be to his face. And then comes the election of Donald Trump, and the emergence of one horrific piece of news after another about the malign ends to which the Facebook platform has been put. To McNamee's shock, even still Facebook's leaders duck and dissemble, viewing the matter as a public relations problem. Now thoroughly alienated, McNamee digs into the issue, and fortuitously meets up with some fellow travelers who share his concern, and help him sharpen its focus. <P><P>Soon he and a dream team of Silicon Valley technologists are charging into the fray, to raise consciousness about the existential threat of Facebook, and the persuasion architecture of the attention economy more broadly -- to our public health and to our political order. Zucked is both an enthralling personal narrative and a masterful explication of the forces that have conspired to place us all on the horns of this dilemma. <P><P>This is the story of a company and its leadership, but it's also a larger tale of a business sector unmoored from normal constraints, just at a moment of political and cultural crisis, the worst possible time to be given new tools for summoning the darker angels of our nature and whipping them into a frenzy. <P><P>Like Jimmy Stewart in Rear Window, Roger McNamee happened to be in the right place to witness a crime, and it took him some time to make sense of what he was seeing and what we ought to do about it. The result of that effort is a wise, hard-hitting, and urgently necessary account that crystallizes the issue definitively for the rest of us. <P><b>A New York Times Bestseller</b>
