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 WAF services

Each cloud provider has its own implementation of a WAF service – that is, an application-layer firewall with capabilities to detect and mitigate common HTTP/HTTPS-based attacks against your publicly exposed web applications.

Securing AWS WAF

AWS WAF is the AWS managed web application firewall service.

AWS WAF offers protection against the following types of attacks:

  • Layer 7 DDoS attacks (when combined with AWS Shield)
  • Common web application attacks
  • Bots (non-human generated traffic)

AWS WAF also allows you to protect the following Amazon services:

  • Amazon CloudFront: The Amazon managed CDN service
  • Amazon API Gateway: The Amazon managed API gateway service
  • Amazon ALB: The Amazon managed Application Load Balancer service (Layer 7 load balancer)

Best practices for securing AWS WAF

The following are some of the best practices to follow:

  • To protect an external web resource, create web ACLs, with...
