What Is a Zero Trust Network? A zero trust network is built upon five fundamental assertio The network is always assumed to be hostile. External and internal threats exist on the network at all times. Network locality is not sufficient for deciding trust in a network. Every device, user, and network flow is authenticated and authorized. Policies must be dynamic and calculated from as many sources of data as possible. From the Preface Who Should Read This Book Have you found the overhead of centralized firewalls to be restrictive? Perhaps you’ve even found their operation to be ineffective? Have you struggled with VPN headaches, TLS configuration across a myriad of applications and languages, or compliance and auditing hardships? These problems represent just a small subset of those addressed by the zero trust model. If you find yourself thinking that there just has to be a better way, then you’re in luck—this book is for you. Network engineers, security engineers, CTOs, and everyone in between can benefit from zero trust learnings. Even without a specialized skillset, many of the principles included within can be clearly understood, helping leaders make decisions that get them closer to realizing the zero trust model, improving their overall security posture incrementally. Additionally, readers with experience using configuration management systems will see the opportunity of using those same ideas to build a more secure and operable networked system—one in which resources are secure by default. They will be interested in how automation systems can enable a new network design that is able to apply fine-grained security controls more easily. Finally, this book also explores mature zero trust design, enabling those who have already incorporated the basic philosophies to further the robustness of their security systems. Zero Trust Networks Today The zero trust model was originally conceived by Forrester’s John Kindervag in 2010. He worked for many years to set forth architectural models and guidance for building zero trust networks and has advised many large companies on how to evolve their security posture in order to attain zero trust guarantees. John was, and still is, an important figure in the field. His work in the area greatly informed our understanding of the state of the union, and we thank him for popularizing zero trust during its formative years. Today’s zero trust networks are largely built using off-the-shelf software components with custom software and glue to integrate the components in novel ways. As such, when reading this text, please be aware that deploying this type of system isn’t as easy as installing and configuring some ready-made hardware or software...yet. It could be said that the lack of easily deployable components that work well together is an opportunity. A suite of open source tools could help drive adoption of zero trust networks.
