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 DNS services

Each cloud provider has its own implementation of managed DNS services – these include services for translating hostnames into IP addresses, different types of DNS records services (such as Alias, CNAME, and more), resolving hostname to load-balance IP, and more.

Securing Amazon Route 53

Amazon Route 53 is the Amazon managed DNS service.

Best practices for securing Amazon Route 53

The following are some of the best practices to follow:

  • Create an Identity and Access Management (IAM) group, add users to the group, and grant the required permissions on the Route 53 service for the target group.
  • Enable Domain Name System Security Extensions (DNSSEC signing) on any public-hosted zone to protect against DNS spoofing attacks.
  • Use a new customer master key (CMK) to sign any newly created public-hosted zone.
  • Make sure privacy protection is enabled for any domain you manage using Route 53 to protect the privacy of domain owners&apos...
