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.

Patch and configuration management in multi-cloud environments

One of the challenges in multi-cloud environments is controlling software updates and configuration changes from a central place. When selecting a patch management solution, look for the following capabilities:

  • The ability to centrally manage patch deployment from a central place
  • Support for deploying security patches on both Windows and Linux platforms
  • Support for asset inventories
  • Support for patch rollback in case of a problematic security patch
  • Support for deploying security patches over secured protocols (such as the TLS tunnel between the central patch server and the remote VM)
  • The ability to deploy security patches to a group of servers (such as different environments and a different patch cycle to avoid breaking availability in case of server clustering)
  • The ability to deploy third-party security patches (such as patches to self-managed database servers, web servers, and client tools...
