Previously, a Principal Architect at Ondat, a cloud-native storage company acquired by Akamai, where he designed products and hybrid cloud solutions and held roles at Tyco, NetApp, and Red Hat becoming a subject matter expert in hybrid cloud. He was moderator and speaker for several events, sharing his insights on culture, process, technology adoption, and passion about open innovation. Xi Chen: Chen Xi is a highly skilled Uber Platform Engineer. As a Tech Leader, he contributed to the Secret and Key Management Platform service, leading and delivering secrets as a service with a 99. 99% SLA for thousands of Uber container services across hybrid environments. His cloud infrastructure prowess is evident from his work on Google Kubernetes Engine (GKE) and the integration of Spire-based PKI systems. Prior to joining Uber, he worked at VMware, where he developed microservices for VMware's Hybrid Kubernetes management platform (Tanzu Mission Control) and VMware Kubernetes Engine for multi-cloud (Cloud PKS). Chen is also a contributing author to the Certified Kubernetes Security Specialist (CKS) exam.

Summary:

Gain hands-on skills in Kubernetes Secrets management, ensuring a comprehensive overview of the Secrets lifecycle and prioritizing adherence to regulatory standards and business sustainability Key Features Master Secrets encryption, encompassing complex life cycles, key rotation, access control, backup, and recovery Build your skills to audit Secrets consumption, troubleshoot, and optimize for efficiency and compliance Learn how to manage Secrets through real-world cases, strengthening your applications' security posture Purchase of the print or Kindle book includes a free PDF eBook Book Description Securing Secrets in containerized apps poses a significant challenge for Kubernetes IT professionals. This book tackles the critical task of safeguarding sensitive data, addressing the limitations of Kubernetes encryption, and establishing a robust Secrets management system for heightened security for Kubernetes. Starting with the fundamental Kubernetes architecture principles and how they apply to the design of Secrets management, this book delves into advanced Kubernetes concepts such as hands-on security, compliance, risk mitigation, disaster recovery, and backup strategies. With the help of practical, real-world guidance, you'll learn how to mitigate risks and establish robust Secrets management as you explore different types of external secret stores, configure them in Kubernetes, and integrate them with existing Secrets management solutions. Further, you'll design, implement, and operate a secure method of managing sensitive payload by leveraging real use cases in an iterative process to enhance skills, practices, and analytical thinking, progressively strengthening the security posture with each solution. By the end of this book, you'll have a rock-solid Secrets management solution to run your business-critical applications in a hybrid multi-cloud scenario, addressing operational risks, compliance, and controls. What you will learn Explore Kubernetes Secrets, related API objects, and CRUD operations Understand the Kubernetes Secrets limitations, attack vectors, and mitigation strategies Explore encryption at rest and external secret stores Build and operate a production-grade solution with a focus on business continuity Integrate a Secrets Management solution in your CI/CD pipelines Conduct continuous assessments of the risks and vulnerabilities for each solution Draw insights from use cases implemented by large organizations Gain an overview of the latest and upcoming Secrets management trends Who this book is for This handbook is a comprehensive reference for IT professionals to design, implement, operate, and audit Secrets in applications and platforms running on Kubernetes. For developer, platform, and security teams experienced with containers, this Secrets management guide offers a progressive path--from foundations to implementation--with a security-first mindset. You'll also find this book useful if you work with hybrid multi-cloud Kubernetes platforms for organizations concerned with governance and compliance requirements.
