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 hybrid cloud environments

When it comes to talking about securing hybrid cloud environments, we are looking for solutions that can manage your entire environment (both on-premises and in the cloud) in a centralized way.

How to secure AWS hybrid environments

AWS offers the following services for managing security in hybrid environments:

  • AWS Systems Manager: This allows you to manage VMs from a compliance, patch management, and hardening perspective (central location for running scripts over hybrid environments).
  • AWS Secrets Manager: A central and secured location for managing secrets (credentials, API keys, and more) over hybrid environments.
  • AWS Elastic Disaster Recovery: Provides secure data replication for disaster recovery between on-premises environments and the cloud.
  • Amazon CloudWatch agent: This allows you to collect OS logs from VMs in hybrid environments.

The following are some best practices to consider:

  • Deploy AWS Systems...
