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 managed database services

Each cloud provider has its own implementation of managed databases.

According to the shared responsibility model, if we choose to use a managed database, the cloud provider is responsible for the operating system and database layers of the managed database (including patch management, backups, and auditing).

If we have the requirement to deploy a specific build of a database, we can always deploy it inside a VM, but according to the shared responsibility model, we will oversee the entire operating system and database maintenance (including hardening, backup, patch management, and monitoring).

A managed solution for running the database engine – either a common database engine such as MySQL, PostgreSQL, Microsoft SQL Server, an Oracle Database server, or proprietary databases such as Amazon DynamoDB, Azure Cosmos DB, or Google Cloud Spanner, but at the end of the day, the basic idea is the same:
