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.

Failing to manage identities

Before we move on to Identity Management (IdM), let's look at a few examples of failing to manage identities:

  • A new employee has joined the organization. Since we do not have a documented and automated IdM workflow, the employee's permissions were copied from a system administrator's profile. The new employee was not aware of which sites they should browse on the internet, and, as result, they were infected by ransomware. This, in turn, infected the sales database, which was encrypted, and caused downtime for the sales division.
  • An employee was able to create an easy-to-guess password (because a complex password policy was not enforced at the organization level), and, as a result, a hacker was able to guess the employee's password and gain access to a confidential financial report.
  • An employee has changed their role in the organization, from IT to the development team, and we forgot to update their privileges on the production...
