"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.

Before an enterprise answers “How can we achieve a Zero Trust architecture?” they should be asking “Why are we looking at Zero Trust as an access model? Does it align with our vision?” In an innovative format, Cisco security architecture expert Avinash Naduvath guides you through the philosophical questions and practical answers for an enterprise looking to start the Zero Trust journey. A conversational model will take you from the initial stages of identifying goals and pitching solutions, through practical tasks that highlight tangible outcomes—including common primary use cases—in order to bring focus to the correct implementation and maintenance of a Zero Trust architecture. For a future where success is measured as much by the security of a system as by the functionality, In Zero Trust We Trust is designed to help everyone at every stage and level of leadership understand not only the conceptual underpinnings, but the real-world context of when, how, and why to deploy Zero Trust security controls. This book provides the starting point for helping you change the mindset of others, and getting them to understand why Zero Trust isn’t simply a conversation to be had, but a movement to embrace. Origins of the Zero Trust philosophy in security architecture explained, and why it took so long to catch on Detailed examination of how to ask the right questions so as to implement the right security answers for clients Understanding the metrics by which to measure Zero Trust success, and what maintaining that success looks like Identifying the stakeholders and empowering a Zero Trust team within an enterprise Examples of how to catalyze opinion and tailor tactics to motivate investment in secure Zero Trust architecture Implement, monitor, feedback, repeat: Presenting and building a roadmap for a sustainable security architecture Looking ahead to a Zero Trust Lifecycle Framework and a blueprint for the future

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 "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.
