Hybrid Cloud Security Patterns

By: Sreekanth Iyer

Overview of this book

Security is a primary concern for enterprises going through digital transformation and accelerating their journey to multi-cloud environments. This book recommends a simple pattern-based approach to architecting, designing and implementing security for workloads deployed on AWS, Microsoft Azure, Google Cloud, and IBM Cloud. The book discusses enterprise modernization trends and related security opportunities and challenges. You’ll understand how to implement identity and access management for your cloud resources and applications. Later chapters discuss patterns to protect cloud infrastructure (compute, storage and network) and provide protection for data at rest, in transit and in use. You’ll also learn how to shift left and include security in the early stages of application development to adopt DevSecOps. The book also deep dives into threat monitoring, configuration and vulnerability management, and automated incident response. Finally, you’ll discover patterns to implement security posture management backed with intelligence and automated protection to stay ahead of threats. By the end of this book, you’ll have learned all the hybrid cloud security patterns and be able to use them to create zero trust architecture that provides continuous security and compliance for your cloud workloads.

Securing serverless implementations

Let’s get started!

Problem

Determining what the patterns for securing serverless deployments or cloud functions should be.

Context

Serverless, as shown in the following diagram, is the latest among the computing type options. It is also called Function as a Service (FaaS). Amazon Web Services (AWS) Lambda, Azure Functions, IBM, and Google Cloud Functions are popular examples of serverless computing models. In this model, an application is broken into separate functions that run when triggered by some action. The consumer is charged only for the processing time used by each function as it executes:

A major challenge with securing serverless functions is that they are short-lived or ephemeral. So, it can be challenging to monitor and detect malicious activity in serverless functions. Serverless functions rely on underlying components and other cloud services...
