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.

What are the cloud service models?

An essential part of understanding clouds is understanding the three cloud service models:

  • Infrastructure as a Service (IaaS): This is the most fundamental service model, where a customer can select the virtual machine size (in terms of the amount of CPU and memory), select a pre-configured operating system, and deploy software inside the virtual machine instance according to business needs (services such as Amazon EC2, Azure Virtual Machines, and Google Compute Engine).
  • Platform as a Service (PaaS): This type of service model varies from managed database services to managed application services (where a customer can import code and run it inside a managed environment) and more (services such as AWS Elastic Beanstalk, Azure Web Apps, and Google App Engine).
  • Software as a Service (SaaS): This is the most widely used service model – a fully managed software environment where, as a customer, you usually open a web browser, log in to an application, and consume services. These could be messaging services, ERP, CRM, business analytics, and more (services such as Microsoft Office 365, Google Workspaces, Salesforce CRM, SAP SuccessFactors, and Oracle Cloud HCM).

Understanding the cloud service models will allow you to understand your role as a customer, explained later in the What is the shared responsibility model? section.
