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 DDoS protection services

Each cloud provider has its own implementation of a managed DDoS protection service.

Because cloud providers have very large bandwidth, they can offer (as a paid service) mechanisms to protect customers' environments from DDoS attacks.

The following services help to mitigate DDoS attacks:

  • DDoS protection services (discussed in this section)
  • Auto-scaling groups combined with load-balancing services
  • CDN services (discussed earlier in this chapter)
  • WAF services (discussed later in this chapter)

In this section, we will focus on DDoS protection services.

Securing AWS Shield

AWS Shield is the Amazon managed DDoS protection service.

It comes in two price models:

  • AWS Shield Standard: This is the default and free Layer 7 DDoS protection (HTTP/HTTPS), provided for all customers.
  • AWS Shield Advanced: This offers Layers 3/4 (Network layer) and Layer 7 (Application layer) DDoS protection, with additional...
