Zero Trust

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

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.

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 book provides you with information on how to implement and manage a zero-trust architecture across these different layers of an infrastructure. It is an introduction to the overall purpose of zero-trust and the benefits that zero-trust can bring to an infrastructure, across many different technologies: Cloud Networking Identity management Operational Technology (OT) 5G Zero-trust is not a product, but a way of thinking about design and architecture. Cisco and Microsoft are used as the technology vendors, but the steps and information are equally applicable to other technology vendors.

"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.

A comprehensive guide to penetration testing cloud services deployed with Microsoft Azure, the popular cloud computing service provider used by companies like Warner Brothers and Apple. Pentesting Azure Applications is a comprehensive guide to penetration testing cloud services deployed in Microsoft Azure, the popular cloud computing service provider used by numerous companies. You'll start by learning how to approach a cloud-focused penetration test and how to obtain the proper permissions to execute it; then, you'll learn to perform reconnaissance on an Azure subscription, gain access to Azure Storage accounts, and dig into Azure's Infrastructure as a Service (IaaS). You'll also learn how to: - Uncover weaknesses in virtual machine settings that enable you to acquire passwords, binaries, code, and settings files - Use PowerShell commands to find IP addresses, administrative users, and resource details - Find security issues related to multi-factor authentication and management certificates - Penetrate networks by enumerating firewall rules - Investigate specialized services like Azure Key Vault, Azure Web Apps, and Azure Automation - View logs and security events to find out when you've been caught Packed with sample pentesting scripts, practical advice for completing security assessments, and tips that explain how companies can configure Azure to foil common attacks, Pentesting Azure Applications is a clear overview of how to effectively perform cloud-focused security tests and provide accurate findings and recommendations.
