The 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 today Explore 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 network Learn how to migrate from a perimeter-based network to a zero trust network in production

This 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 agents Understand how this model embeds security within the system's operation, with guided scenarios at the end of each chapter Migrate from a perimeter-based network to a zero trust network in production Explore case studies that provide insights into organizations' zero trust journeys Learn about the various zero trust architectures, standards, and frameworks developed by NIST, CISA, DoD, and others

Perimeter defenses guarding your network aren't as secure as you might 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. This practical book introduces you to the zero trust model, a method that treats all hosts as if they're internet-facing, and considers the entire network to be compromised and hostile. In this updated edition, the authors show you how zero trust lets you focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. You'll learn the architecture of a zero trust network, including how to build one using currently available technology. Explore fundamental concepts of a zero trust network, including trust engine, policy engine, and context aware agents Understand how this model embeds security within the system's operation, rather than layering it on top Use existing technology to establish trust among the actors in a network Migrate from a perimeter-based network to a zero trust network in production Examine case studies that provide insights into various organizations' zero trust journeys Learn about the various zero trust architectures, standards, and frameworks

Secure your VMware infrastructure against distrusted networks using VMware NSX. This book shows you why current security firewall architecture cannot protect against new threats to your network and how to build a secure architecture for your data center. Author Sreerjith Keeriyattil teaches you how micro-segmentation can be used to protect east-west traffic. Insight is provided into working with Service Composer and using NSX REST API to automate firewalls. You will analyze flow and security threats to monitor firewalls using VMware Log and see how Packet Flow works with VMware NSX micro-segmentation. The information presented in Zero Trust Networks with VMware NSX allows you to study numerous attack scenarios and strategies to stop these attacks, and know how VMware Air Watch can further improve your architecture. What You Will LearnKnow how micro-segmentation works and its benefitsImplement VMware-distributed firewallsAutomate security policies Integrate IPS/IDS with VMware NSXAnalyze your firewall's configurations, rules, and policies Who This Book Is For Experienced VMware administrators and security administrators who have an understanding of data center architecture and operations

This book delves into the complexities of business settings. It covers the practical guidelines and requirements your security team will need to design and execute a zero-trust journey while maximizing the value of your current enterprise security architecture. The goal of Zero Trust is to radically alter the underlying concept and approach to enterprise security, moving away from old and clearly unsuccessful perimeter-centric techniques and toward a dynamic, identity-centric, and policy-based approach. This book helps the readers to earn about IPS, IDS, and IDPS, along with their varieties and comparing them. It also covers Virtual Private Networks, types of VPNs.and also to understand how zero trust and VPN work together By the completion of the book, you will be able to build a credible and defensible Zero Trust security architecture for your business, as well as implement a step-by-step process that will result in considerably better security and streamlined operations.

Today's organizations need a new security model that more effectively adapts to the complexity and risks of modern environments, embraces hybrid workplaces, and protects people, devices, apps, and data wherever they're located. Zero Trust is the first model with the potential to do all that. Zero Trust Architecture: Theory, Implementation, Maintenance, and Growth is the first comprehensive guide for architects, engineers, and other technical professionals who want to move from Zero Trust theory to implementation and successful ongoing operation. A team of Cisco's leading experts and implementers offer the most comprehensive and substantive guide to Zero Trust, bringing clarity, vision, practical definitions, and real-world expertise to a space that's been overwhelmed with hype. The authors explain why Zero Trust identity-based models can enable greater flexibility, simpler operations, intuitive context in the implementation and management of least privilege security. Then, building on Cisco's own model, they systematically illuminate methodologies, supporting technologies, and integrations required on the journey to any Zero Trust identity-based model. Through real world experiences and case study examples, you'll learn what questions to ask, how to start planning, what exists today, what solution components still must emerge and evolve, and how to drive value in the short-term as you execute on your journey towards Zero Trust.

Once you know what a zero trust network is, and what the advantages and disadvantages of moving to this model are, the next step is to understand some of the common challenges that you will face in implementing zero trust as a security model. Evan Gilman and Doug Barth discuss these challenges, and give suggestions on how to overcome them. You will get tips on why to involve more than just your security team, why implementing policy as code is important, understanding why you should evaluate policies for their impact and value, and the overall scale of change involved in moving from a perimeter model to a zero trust model. Doug Barth is a software engineer who loves to learn and share his knowledge with others. He has worked on systems of various sizes at companies like Orbitz and PagerDuty. He has built and spoken about monitoring systems, mesh networks, and failure injection practices. Evan Gilman is an Operations Engineer with a background in computer networks. With roots in academia, and currently working in the public internet, he has been building and operating systems in hostile environments his entire professional career. An open source contributor, speaker, and author, Evan is passionate about designing systems that strike a balance with the networks they run on.
