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.

Conducting threat detection and response

In the previous section, we spoke about a way to log activity in our cloud environment (what was done, when, and by whom).

In this section, we will review managed services that allow us to review our logs and pinpoint actual threats and our response to the threats.

Using Amazon Detective for threat detection

Amazon Detective connects to services such as AWS CloudTrail and Amazon VPC Flow Logs to detect login events, API calls, and network traffic.

It then uses machine learning to detect activities outside normal behavior to assist you in finding the root cause of suspicious activities in your AWS environment.

Amazon Detective is the cloud-native equivalent of third-party tools such as Splunk, which allows you to query a large number of logs and detect security-related incidents.
