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.

Cloud Infrastructure Entitlement Management (CIEM)

A new concept developed in the past couple of years is CIEM. Some vendors offer a combined solution of both CSPM and CIEM into a single product, which factors in a multi-cloud partner strategy.

CIEM solutions allow us to monitor and manage identities (both human and machine) and access privileges in a multi-cloud environment, from a central console, while applying the principle of least privilege access to our cloud infrastructure. When selecting a CIEM solution, look for the following capabilities:

  • Support for multiple cloud providers
  • An inventory of existing entitlements
  • Detecting and remediating IAM misconfigurations
  • The ability to control access to resources, services, and administrative accounts
  • Identifying risks associated with configuration errors
  • Identifying shadow admin accounts in a multi-cloud environment
  • Suggestions for policy correction
  • Auto-generation of access policies according...
