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.

Network isolation patterns

Let's get started!

Problem

Why is network isolation needed and how can we achieve network isolation?

Context

Most organizations’ applications are distributed across different data centers and multiple cloud environments based on business needs. These applications need to connect to other cloud and on-premises applications to fulfill their functions. Networks are currently protected with perimeter-based network security. This mostly enables what is called north-south (client to server) traffic and is typically done by leveraging network firewalls. But applications or assets within the network are generally trusted, and east-west traffic is allowed without any controls. This traditional approach of network protection cannot be extended to the cloud because if the network gets attacked, it exposes the entire internal and external network that is spread across the cloud. Modern security thinking, in fact, says that you should assume that...
