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.

Chapter 10: Engaging with Cloud Providers

In previous chapters, we have covered cloud infrastructure fundamentals, common threats in cloud environments, and how to handle compliance and regulation. This chapter will cover fundamental steps prior to working with cloud services, such as engaging with cloud providers.

In the traditional data center, we control everything – from physical to logical security controls. To get assurance when working with cloud providers, there are several options, such as the following:

  • Conduct a risk assessment prior to engaging with a cloud provider – one good option is to review SOC2 Type 2 reports (what controls the cloud provider has set and how effective they are).
  • Have a good contract that clearly sets the obligations of the cloud provider (such as an Service Level Agreement (SLA) for handling security incidents and an SLA to notify us as customers).
  • Conduct a penetration test at least once every 12 months on the system...
