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

Numerous publications exist which examine elements of the security discipline. Few address these elements as a continuum of interrelated functions. None examine the structure of Offensive vice Defensive security in anything other than the domain of international security . This text has been written to fill this gap and to support a course in Offensive-Defensive Security, developed by Henley-Putnam University, which briefly reviews the history of the field of strategic security and its three component parts – protection, intelligence, and counterterrorism – as well as its two distinguishing characteristics: offensive tactics and operations combined with technological innovation. The course then moves to an in-depth assessment of related security areas that focus on defensive tactics and operations: homeland security, criminal justice, conflict and peace studies, and emergency management. While these fields may appear – at first – to be part of strategic security, this course and the associated text explores the critical differences and the fact that they are also critical elements of industrial, governmental, and military security. Emphasis will be placed at an introductory level – both academic and professional distinctions – and discuss the structures associated within these domains. The text is divided into the following key sections: Section 1: The Basics Section 2: The Environment Section 3: Security Planning and Management Section 1 provides an orientation for the reader to a common frame of reference through information provided in the following chapters. It is not intended to be a single source of all relevant information. Additionally, this text is not intended to be the exhaustive single source for all conditions. Rather, it provides a roadmap of considerations on how to reach a specific goal in an efficient and informed manner. Section 2 examines the world the security professional must inhabit, again, in a generalized manner and, likely, in a way never before considered. Elements of neurology, biology, physics, philosophy, logic, analytics, and finance are presented in a manner unique to the changing paradigm of Offensive-Defensive Security philosophy. The various chapters are labeled as ‘terrains’ as the best representation of the environmental information to be discussed. Each will approach the topics in as clear a manner possible of current thinking and science within each as critical to the understanding of the total security environment; the how, why, and in what ways they will affect the world of this security paradigm. Finally, Section 3 incorporates the information of the first two sections and applies the knowledge gained to the planning and management of an integrated security plan. The objective of this section is to utilize the concepts and processes developed via international agencies such as the Project Management Institute to demonstrate how to create an integrated and manageable enterprise structure and not a one-size fits all template. As the knowledge consolidates, integration begins, that of incorporating the security entity into the enterprise as a whole be that enterprise be a business, government entity, or military operation. The only difference is the scale. This is a vital step in that the act of protection cannot interfere with the process of performing the enterprise function. In fact, it must enhance the enterprise function and assist in ensuring its success. Key Learning Points The approach and purpose of this text has been outlined. The following are the key reasons or learning points in summary. a. Define the key elements and environments within which the security plan and operational management activities must occur b. Familiarize the student with cultural, biological, financial, informational, and legal aspects necessary for the understanding of how these domains influence human behavior; the primary aspect of security planning and operations c.

End-to-End Network Security Defense-in-Depth Best practices for assessing and improving network defenses and responding to security incidents Omar Santos Information security practices have evolved from Internet perimeter protection to an in-depth defense model in which multiple countermeasures are layered throughout the infrastructure to address vulnerabilities and attacks. This is necessary due to increased attack frequency, diverse attack sophistication, and the rapid nature of attack velocity—all blurring the boundaries between the network and perimeter. End-to-End Network Security is designed to counter the new generation of complex threats. Adopting this robust security strategy defends against highly sophisticated attacks that can occur at multiple locations in your network. The ultimate goal is to deploy a set of security capabilities that together create an intelligent, self-defending network that identifies attacks as they occur, generates alerts as appropriate, and then automatically responds. End-to-End Network Security provides you with a comprehensive look at the mechanisms to counter threats to each part of your network. The book starts with a review of network security technologies then covers the six-step methodology for incident response and best practices from proactive security frameworks. Later chapters cover wireless network security, IP telephony security, data center security, and IPv6 security. Finally, several case studies representing small, medium, and large enterprises provide detailed example configurations and implementation strategies of best practices learned in earlier chapters. Adopting the techniques and strategies outlined in this book enables you to prevent day-zero attacks, improve your overall security posture, build strong policies, and deploy intelligent, self-defending networks. “Within these pages, you will find many practical tools, both process related and technology related, that you can draw on to improve your risk mitigation strategies.” —Bruce Murphy, Vice President, World Wide Security Practices, Cisco Omar Santos is a senior network security engineer at Cisco®. Omar has designed, implemented, and supported numerous secure networks for Fortune 500 companies and the U.S. government. Prior to his current role, he was a technical leader within the World Wide Security Practice and the Cisco Technical Assistance Center (TAC), where he taught, led, and mentored many engineers within both organizations.
