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.

The monitoring and auditing of multi-cloud environments

Monitoring is a crucial part of multi-cloud visibility. It can have multiple layers, such as the following:

  • Resource utilization (performance logging)
  • Monitoring running applications for errors (application logging)
  • Security auditing and logging to detect security incidents

In this section, we will focus on security monitoring. When selecting a security monitoring solution for multi-cloud environments, look for the following capabilities:

  • The ability to connect to multiple cloud providers, using the native cloud provider APIs
  • The ability to connect to remote APIs using secured protocols (such as TLS 1.2)
  • Built-in connectors for multiple cloud solutions (both common Infrastrucure as a Service (IaaS)/Platform as a Service (PaaS) and SaaS)
  • The ability to receive feeds from threat detection services such as Amazon GuardDuty, Microsoft Defender for Cloud, and Google Security Command Center...
