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.

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.

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

One of the basic tenets of zero trust is to remove the implicit trust in users, services, and devices based only on their network location, affiliation, and ownership. NIST Special Publication 800-207 has laid out a comprehensive set of zero trust principles and referenced zero trust architectures (ZTA) for turning those concepts into reality. A key paradigm shift in ZTAs is the change in focus from security controls based on segmentation and isolation using network parameters (e.g., IP addresses, subnets, perimeter) to identities. From an application security point of view, this requires authentication and authorization policies based on application and service identities in addition to the underlying network parameters and user identities. This in turn requires a platform that consists of API gateways, sidecar proxies, and application identity infrastructures (e.g., Secure Production Identity Framework for Everyone [SPIFFE]) that can enforce those policies irrespective of the location of the services or applications, whether on-premises or on multiple clouds. The objective of this publication is to provide guidance for realizing an architecture that can enforce granular application-level policies while meeting the runtime requirements of ZTA for multi-cloud and hybrid environments.

"Zero Trust is the strategy that organizations need to implement to stay ahead of cyber threats, period. The industry has 30 plus years of categorical failure that shows us that our past approaches, while earnest in their efforts, have not stopped attackers. Zero Trust strategically focuses on and systematically removes the power and initiatives hackers and adversaries need to win as they circumvent security controls. This book will help you and your organization have a better understanding of what Zero Trust really is, recognize its history, and gain prescriptive knowledge that will help you and your enterprise finally begin beating the adversaries in the chess match that is cyber security strategy." Dr. Chase Cunningham (aka Dr. Zero Trust), Cyberware Expert Today’s organizations require a new security approach that effectively adapts to the challenges of the modern environment, embraces the mobile workforce, and protects people, devices, apps, and data wherever they are located. Zero Trust is increasingly becoming the critical security approach of choice for many enterprises and governments; however, security leaders often struggle with the significant shifts in strategy and architecture required to holistically implement Zero Trust. This book seeks to provide an end-to-end view of the Zero Trust approach across organizations’ digital estates that includes strategy, business imperatives, architecture, solutions, human elements, and implementation approaches that could significantly enhance these organizations' success in learning, adapting, and implementing Zero Trust. The book concludes with a discussion of the future of Zero Trust in areas such as artificial intelligence, blockchain technology, operational technology (OT), and governance, risk, and compliance. The book is ideal for business decision makers, cybersecurity leaders, security technical professionals, and organizational change agents who want to modernize their digital estate with the Zero Trust approach.

Many of the security counter measures being leveraged by businesses today simply address the past (trust then verify). These tools advise and protect when issues are detected, then the problems can be addressed. There is often a time lag from identification, addressing the issues, and resolving the actual issues. To understand the overall state of security in an organization there are a considerable number of tools required. For the most part, each of these tools have an application agent to be deployed. The result is often a “one of everything” approach. Zero Trust is a framework not a solution. Zero Trust is a part of an ongoing continuous process improvement plan, and should evolve with the times to deliver true security to an organization. The common thread is the ability to identify known vectors of end user satisfaction or organizational risk to address issues. The comment about “known” vectors is the key - security counter measures can only respond to what is known and understood at a particular moment in time. Risk is a very straightforward concept. Risk is either real or not. Closed Loop Lifecycle Planning© in its research called The Risk Cycle© concluded that risk does not have a “gray” area - something is either a risk or not. Our book has challenged the assumption that there is such a thing as “reasonable risk”. The theory of reasonable risk is that businesses and organizations make a conscious decision that a risk is reasonable to take, and then accepts the exposure. Zero Trust would argue that the approach itself is not reasonable.
