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.

Securing VPN services

Each cloud provider has its own implementation of a VPN service. VPNs allow network-based access to private resources over untrusted networks.

Following are some of the common VPN services concepts:

  • Combined with a firewall, a VPN allows organizations to access and manage their internal resources (both sides of the VPN tunnel) in a secure manner.
  • A VPN allows corporate users to connect to their organization's cloud environment from either the corporate network or from home.
  • The connection between the VPN and the cloud environment is encrypted.
  • The connection to the cloud environment is transparent (that is, the same as working locally from the corporate network).
  • The VPN can enforce the use of multi-factor authentication (MFA) for end users connecting using a client VPN.

In this section, we will review how site-to-site VPN services and client VPN services can allow connectivity to your cloud environment.
