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

▶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.

출판사 서평

▶ Preface
Kubernetes Secrets management is a combination of practices and tools that help users to securely store and manage sensitive information, such as passwords, tokens, and certificates, within a Kubernetes cluster and keep them safe and secure. Securing Secrets such as passwords, API keys, and other sensitive information is critical for protecting applications and data from unauthorized access. Developers who understand Kubernetes Secrets management can help ensure that Secrets are managed securely and effectively, reducing the risk of security breaches. Many industries and regulatory frameworks have specific requirements for managing sensitive data. By learning Kubernetes Secrets management practices, developers can ensure that their applications comply with these requirements and avoid potential legal or financial penalties.
