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 CDN services

Each cloud provider has its own implementation of a CDN service – that is, a service for distributing content closer to the customer throughout the entire world.

A CDN caches content (such as images, videos, or static web pages) in multiple locations around the world, allowing customers to receive the content quickly from a location close to the customer.

CDNs also serve as an extra defense mechanism against DDoS attacks by being one of the first services that serves a customer's request, even before the request reaches the servers or applications.

Securing Amazon CloudFront

Amazon CloudFront is the AWS managed CDN service.

Best practices for securing Amazon CloudFront

The following are some of the best practices to follow:

  • Restrict access to origin servers (where your original content is stored) from CDN segments only (allow traffic only from the CDN segments towards servers or services that store content).
  • Share content...
