Book Description
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

Book Description
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

Book Description
"The book you are about to read will arm you with the knowledge you need to defend your network from attackers—both the obvious and the not so obvious.... If you are new to network security, don't put this book back on the shelf! This is a great book for beginners and I wish I had access to it many years ago. If you've learned the basics of TCP/IP protocols and run an open source or commercial IDS, you may be asking 'What's next?' If so, this book is for you." —Ron Gula, founder and CTO, Tenable Network Security, from the Foreword "Richard Bejtlich has a good perspective on Internet security—one that is orderly and practical at the same time. He keeps readers grounded and addresses the fundamentals in an accessible way." —Marcus Ranum, TruSecure "This book is not about security or network monitoring: It's about both, and in reality these are two aspects of the same problem. You can easily find people who are security experts or network monitors, but this book explains how to master both topics." —Luca Deri, ntop.org "This book will enable security professionals of all skill sets to improve their understanding of what it takes to set up, maintain, and utilize a successful network intrusion detection strategy." —Kirby Kuehl, Cisco Systems Every network can be compromised. There are too many systems, offering too many services, running too many flawed applications. No amount of careful coding, patch management, or access control can keep out every attacker. If prevention eventually fails, how do you prepare for the intrusions that will eventually happen? Network security monitoring (NSM) equips security staff to deal with the inevitable consequences of too few resources and too many responsibilities. NSM collects the data needed to generate better assessment, detection, and response processes—resulting in decreased impact from unauthorized activities. In The Tao of Network Security Monitoring , Richard Bejtlich explores the products, people, and processes that implement the NSM model. By focusing on case studies and the application of open source tools, he helps you gain hands-on knowledge of how to better defend networks and how to mitigate damage from security incidents. Inside, you will find in-depth information on the following areas. The NSM operational framework and deployment considerations. How to use a variety of open-source tools—including Sguil, Argus, and Ethereal—to mine network traffic for full content, session, statistical, and alert data. Best practices for conducting emergency NSM in an incident response scenario, evaluating monitoring vendors, and deploying an NSM architecture. Developing and applying knowledge of weapons, tactics, telecommunications, system administration, scripting, and programming for NSM. The best tools for generating arbitrary packets, exploiting flaws, manipulating traffic, and conducting reconnaissance. Whether you are new to network intrusion detection and incident response, or a computer-security veteran, this book will enable you to quickly develop and apply the skills needed to detect, prevent, and respond to new and emerging threats.

Book Description
The Cybersecurity landscape is a daunting one today. It is nothing like it was 10 years ago. Now, it has become very complex, covert, dynamic, and stealthy. It has literally become a cat and mouse game, in which the Cyberattacker is still one step ahead. This is despite all of the technology that is available to us a society, which includes Artificial Intelligence (AI) and Machine Learning. Part of the other problem is that human beings are resistant to change. For example, the password is still the favored way of authenticating and authorizing an individual, but it too has shown its grave limitations. Despite the use of Password Managers, which can create long and complex passwords, people still resort to their old fashioned ways of doing things. So what is needed now is an extreme change, in which, unfortunately, people have no choice in whether or not they will participate. It is called the Zero Trust Framework, and in this methodology, absolutely nobody can be trusted in either the internal or the external environments. The mantra here is to keep verifying everybody, all the time. The Zero Trust Framework also involves the concept of segmentation, in which the IT and Network Infrastructure of a business is broken down into smaller components, much like a Subnet. Each component will have its own layer of security, and every individual must be authenticated via the use of Multifactor Authentication (MFA). In this book, we review both the concepts and mechanics behind the Zero Trust Framework. We also introduce advanced technologies into it, including the use of Biometrics, the Public Key Infrastructure, and Quantum Mechanics/Quantum Cryptography.
