Policy as Code
In today's cloud native world, where we automate as much as possible, everything is code. With this practical guide, you'll learn how Policy as Code (PaC) provides the means to manage the policies, related data, and responses to events that occur within the systems we maintain—Kubernetes, cloud security, software supply chain security, infrastructure as code, and microservices authorization, among others. Author Jimmy Ray provides a practical approach to integrating PaC solutions into your systems, with plenty of real-world examples and important hands-on guidance. DevOps and DevSecOps engineers, Kubernetes developers, and cloud engineers will understand how to choose and then implement the most appropriate solutions. Understand PaC theory, best practices, and use cases for security Learn how to choose and use the correct PaC solution for your needs Explore PaC tooling and deployment options for writing and managing PaC policies Apply PaC to DevOps, IaC, Kubernetes, and AuthN/AuthZ Examine how you can use PaC to implement security controls Verify that your PaC solution is providing the desired result Create auditable artifacts to satisfy internal and external regulatory requirements
Mastering Open Policy Agent
"Mastering Open Policy Agent: Policy-Based Control for Modern Systems" is an essential guide for IT professionals seeking to implement robust policy management within their technology environments. This comprehensive resource explores Open Policy Agent (OPA), an open-source, policy-as-code framework that empowers organizations to enforce consistency, security, and compliance across diverse systems. Through clear explanations and practical insights, readers gain a deep understanding of OPA's architecture, its powerful Rego language, and the practical application of policies in real-world scenarios. The book systematically presents foundational concepts, detailed setup guides, and advanced techniques to equip readers with the skills needed to integrate OPA seamlessly into various technological domains, including Kubernetes, cloud services, and microservices architectures. By addressing complex topics such as distributed policy enforcement, dynamic policy execution, and optimization strategies, this book is designed to meet the needs of both novices and seasoned practitioners. Whether enhancing security, automating compliance, or streamlining governance processes, readers will discover how to leverage OPA to build scalable, reliable, and adaptable policy solutions for modern IT challenges.

Want to run your Kubernetes workloads safely and securely? This practical book provides a threat-based guide to Kubernetes security. Each chapter examines a particular component's architecture and potential default settings and then reviews existing high-profile attacks and historical Common Vulnerabilities and Exposures (CVEs). Authors Andrew Martin and Michael Hausenblas share best-practice configuration to help you harden clusters from possible angles of attack. This book begins with a vanilla Kubernetes installation with built-in defaults. You'll examine an abstract threat model of a distributed system running arbitrary workloads, and then progress to a detailed assessment of each component of a secure Kubernetes system. Understand where your Kubernetes system is vulnerable with threat modelling techniques Focus on pods, from configurations to attacks and defenses Secure your cluster and workload traffic Define and enforce policy with RBAC, OPA, and Kyverno Dive deep into sandboxing and isolation techniques Learn how to detect and mitigate supply chain attacks Explore filesystems, volumes, and sensitive information at rest Discover what can go wrong when running multitenant workloads in a cluster Learn what you can do if someone breaks in despite you having controls in place
