Cloud Security Handbook

By: Eyal Estrin

Overview of this book

Securing resources in the cloud is challenging, given that each provider has different mechanisms and processes. Cloud Security Handbook helps you to understand how to embed security best practices in each of the infrastructure building blocks that exist in public clouds. This book will enable information security and cloud engineers to recognize the risks involved in public cloud and find out how to implement security controls as they design, build, and maintain environments in the cloud. You'll begin by learning about the shared responsibility model, cloud service models, and cloud deployment models, before getting to grips with the fundamentals of compute, storage, networking, identity management, encryption, and more. Next, you'll explore common threats and discover how to stay in compliance in cloud environments. As you make progress, you'll implement security in small-scale cloud environments through to production-ready large-scale environments, including hybrid clouds and multi-cloud environments. This book not only focuses on cloud services in general, but it also provides actual examples for using AWS, Azure, and GCP built-in services and capabilities. By the end of this cloud security book, you'll have gained a solid understanding of how to implement security in cloud environments effectively.

Securing directory services

Each cloud provider has its own implementation of a managed Active Directory service. This service allows you to centrally manage your user and computer identities, join Windows machines to the Active Directory domain, set password policies (such as the password length, password complexity, and more), and control access to traditional resources (such as Windows file shares, SQL servers, IIS servers, and more).

It is important to note that as a customer, you always have the option to deploy Active Directory domain controllers based on virtual machines and maintain them yourself, as organizations are doing on-premises (this is also known as a self-hosted solution). However, the goal of this book is to show you how things are done using managed services, where, as a customer, you can focus on consuming the IAM service (that is, authenticate and create identities and then grant them permissions) without having to maintain servers (such as availability, patch...
