Microsoft Azure Fundamentals Certification and Beyond

By: Steve Miles

Overview of this book

This is the digital and cloud era, and Microsoft Azure is one of the top cloud computing platforms. It’s now more important than ever to understand how the cloud functions and the different services that can be leveraged across the cloud. This book will give you a solid understanding of cloud concepts and Microsoft Azure, starting by taking you through cloud concepts in depth, then focusing on the core Azure architectural components, solutions, and management tools. Next, you will understand security concepts, defense-in-depth, and key security services such as Network Security Groups and Azure Firewall, as well as security operations tooling such as Azure Security Center and Azure Sentinel. As you progress, you will understand how identity, governance, privacy, and compliance are managed in Azure. Finally, you will get to grips with cost management, service-level agreements, and service life cycles. Throughout, the book features a number of hands-on exercises to support the concepts, services, and solutions discussed. This provides you with a glimpse of real-world scenarios, before finally concluding with practice questions for AZ-900 exam preparation. By the end of this Azure book, you will have a thorough understanding of cloud concepts and Azure fundamentals, enabling you to pass the AZ-900 certification exam easily.

Network and application protection

This section introduces the core solutions available in Azure to protect and secure the network and applications running in Azure; this section also covers solutions that, while not part of the exam objectives, have been included with brief coverage as they should be considered required knowledge for a day-to-day Azure role.

NSGs

An NSG is a network security control and should be part of your DoD approach to protecting the network layer from network threats.

An NSG controls access, limits connections to virtual machines (VMs) in an Azure Virtual Network (VNet), and uses a deny-by-default policy; this means that all access is denied unless explicitly allowed. The following diagram shows a simplification of this:

Figure 7.7 – VM access

In the preceding diagram, Subnet 1 has no traffic filtering in place, so you would be able to connect to Windows VM1 using Remote Desktop Protocol (RDP) on port 3389, and so can...
