Zero Trust Networks With Vmware Nsx

Secure your VMware infrastructure against distrusted networks using VMware NSX. This book shows you why current security firewall architecture cannot protect against new threats to your network and how to build a secure architecture for your data center. Author Sreerjith Keeriyattil teaches you how micro-segmentation can be used to protect east-west traffic. Insight is provided into working with Service Composer and using NSX REST API to automate firewalls. You will analyze flow and security threats to monitor firewalls using VMware Log and see how Packet Flow works with VMware NSX micro-segmentation. The information presented in Zero Trust Networks with VMware NSX allows you to study numerous attack scenarios and strategies to stop these attacks, and know how VMware Air Watch can further improve your architecture. What You Will LearnKnow how micro-segmentation works and its benefitsImplement VMware-distributed firewallsAutomate security policies Integrate IPS/IDS with VMware NSXAnalyze your firewall's configurations, rules, and policies Who This Book Is For Experienced VMware administrators and security administrators who have an understanding of data center architecture and operations

The planning of micro-segmentation can be an overwhelming task because most organizations have tens to thousands of applications in their data centers. Knowing which applications and how to start planning for the implementation of a Zero-Trust security posture with VMware NSX and micro-segmentation is critical. As we go through VMware NSX Micro-Segmentation ¿ Day 1 Practical Guide, we will arm you with the knowledge you need to begin building a scalable methodology and planning for the applications you are going to secure. For immediate micro-segmentation needs, we'll take a look at VMware Log Insight. We¿ll cover the new feature in NSX 6.3 called Application Rule Manager, which scales up our ability to plan and implement Distributed Firewall Rulesets. And finally, we¿ll look at vRealize Network Insight, a product that introduces data center scale security planning and operations. We will compare and contrast when to use each tool, and demonstrate detailed step-by-step processes for using them.

Software-defined network (SDN) and network function virtualization (NFV) are two technology trends that have revolutionized network management, particularly in highly distributed networks that are used in public, private, or hybrid cloud services. SDN and NFV technologies, when combined, simplify the deployment of network resources, lower capital and operating expenses, and offer greater network flexibility. The increasing usage of NFV is one of the primary factors that make SDN adoption attractive. The integration of these two technologies; SDN and NFV, offer a complementary service, with NFV delivering many of the real services controlled in an SDN. While SDN is focused on the control plane, NFV optimizes the actual network services that manage the data flows. Devices such as routers, firewalls, and VPN terminators are replaced with virtual devices that run on commodity hardware in NFV physical networking. This resembles the 'as-a-service' typical model of cloud services in many aspects. These virtual devices can be accessed on-demand by communication, network, or data center providers.This book illustrates the fundamentals and evolution of SDN and NFV and highlights how these two technologies can be integrated to solve traditional networking problems. In addition, it will focus on the utilization of SDN and NFV to enhance network security, which will open ways to integrate them with current technologies such as IoT, edge computing and blockchain, SDN-based network programmability, and current network orchestration technologies. The basics of SDN and NFV and associated issues, challenges, technological advancements along with advantages and risks of shifting networking paradigm towards SDN are also discussed. Detailed exercises within the book and corresponding solutions are available online as accompanying supplementary material.

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

Micro-segmentation - Day 1 brings together the knowledge and guidance for planning, designing, and implementing a modern security architecture for the software-defined data center based on micro-segmentation. VMware NSX makes network micro-segmentation feasible for the first time. It enables granular firewalling and security policy enforcement for every workload in the data center, independent of the network topology and complexity. Micro-segmentation with NSX already helped over a thousand organizations improve the security posture of their software-defined data center by fundamentally changing the way they approach security architecture. Micro-segmentation - Day 1 is your roadmap to simplify and enhance security within software-defined data centers running NSX. You will find insights and recommendations proven in the field for moving your organization from a perimeter-centric security posture to a micro-segmented architecture that provides enhanced security and visibility within your data center.

This primer on NSX-T helps you understand the capabilities and features of NSX-T, how to configure and manage NSX-T, and integrate NSX-T with other software. The book is the first in a series that will teach you the basics of NSX-T, which is an update of VMware's original software-defined networking (SDN) architecture aimed at making networks agile and flexible. You will become familiar with VMware's software-defined data center (SDDC) ecosystem and how NSX-T fits in. You will understand NSX-T components such as NSX-T Manager, NSX-T Edge Transport Nodes, and NSX-T Host Transport Nodes. And you will learn how to install and configure network services such as East/West and North/South routing capabilities, layer two switching, VRF, EVPN, multicast, and layer two bridging. The book provides best practices on how to configure routing and switching features, and teaches you how to get the required visibility of not only your NSX-T platform but also your NSX-T-enabled network infrastructure. The book explains security, advanced network features, and multi-site capabilities and demonstrates how network and security services can be offered across multiple on-premise locations with a single pane of glass for networking and security policy management.
