The "Zero Trust" architecture (ZTA ) effectively responds to data breaches and ransomware attacks. Zero Trust is a security ideology based upon the principles of continuously authenticating and verifying users' access to devices, workloads, applications, and systems. As the name sounds, it means no trust in user or system access requests, devices, or IT infrastructure. The cybersecurity products enabled with Zero Trust security can help IT management redesign access management, dynamic policy updates, micro-segmentation around critical applications, and secure diverse endpoints to reduce attack surfaces with fewer complexities. The Zero Trust framework helps cybersecurity professionals to defend vastly dispersed and complex networks from insider and external cyber threats. Zero Trust architecture is a significant shift in the security paradigm [1]. It requires access control implementations to hold that no implicit trust may be awarded for any user or device, even with a prior history of successful validated authentication and authorization. Over the last two decades, it is essential to understand how network security has evolved from perimeter-driven network security to Zero Trust security, which places security controls at user, resource, workloads, and micro-segment levels. Zero Trust can replace the traditional complexities of integrating dynamic data centers, distributed workloads, endpoints, remote users, and cloud application landscape and can stop bad actors from exploiting the enterprise network. ColorTokens' response to a surge in recent cyberattacks is to advocate the adoption of Zero Trust architecture and provide products enabled with Zero Trust principles and services to enterprises. This project created an opportunity to review ColorTokens Zero Trust products and services. The choice of ColorTokens products is due to its high rating in the year 2020 for five categories under which it got the best Zero Trust security awards [2]. The project scope includes an analysis of Zero Trust architecture, and a review of ColorTokens Zero Trust enabled products that benefit enterprises in reducing the attack surface. The author believes that the information presented in this paper will help cybersecurity professionals to explore the benefits of Zero Trust and add it to securing networks and data they are the guardian of protecting.

"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.

Zero trust (ZT) is the term for an evolving set of cybersecurity paradigms that move defenses from static, network- based perimeters to focus on users, assets, and resources. A zero trust architecture (ZTA) uses zero trust principles to plan industrial and enterprise infrastructure and workflows. Zero trust assumes there is no implicit trust granted to assets or user accounts based solely on their physical or network location (i.e., local area networks versus the internet) or based on asset ownership (enterprise or personally owned). Authentication and authorization (both subject and device) are discrete functions performed before a session to an enterprise resource is established. Zero trust is a response to enterprise network trends that include remote users, bring your own device (BYOD), and cloud- based assets that are not located within an enterprise-owned network boundary. Zero trust focus on protecting resources (assets, services, workflows, network accounts, etc.), not network segments, as the network location is no longer seen as the prime component to the security posture of the resource. This document contains an abstract definition of zero trust architecture (ZTA) and gives general deployment models and use cases where zero trust could improve an enterprise's overall information technology security posture.

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
