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 5: Effective Strategies to Implement IAM Solutions

From Chapter 2, Securing Compute Services, to Chapter 4, Securing Network Services, we covered the fundamental building blocks of cloud services (from compute and storage to networking services).

However, we cannot talk about cloud services without also discussing identity management.

In this chapter, we will cover various concepts of identity management – from traditional directory services (based on the Kerberos protocol in the Microsoft environment, LDAP-based directory services, popular in non-Microsoft environments, and even Linux-based directory services) to modern directory services (based on the SAML or OAuth protocols) – and, finally, we will understand how to secure authentication mechanisms based on Multi-Factor Authentication (MFA).

In this chapter, we will cover the following topics:

  • Introduction to IAM
  • Failing to manage identities
  • Securing cloud-based IAM services
  • Securing...
