As Kubernetes continues to dominate the container orchestration landscape, the security of its deployments, particularly through Helm, has become a paramount concern. This review paper explores the multifaceted security challenges inherent in Kubernetes environments, with a specific focus on Helm, a popular package manager that simplifies the deployment and management of Kubernetes applications. By dissecting the primary security vulnerabilities related to container orchestration, such as isolation flaws, misconfigurations, and network security complexities, this paper provides a comprehensive overview of the current security measures and best practices. Additionally, it delves into Helm-specific security considerations, including the architecture of Helm, its operational dynamics, and strategies for securing Helm deployments. Through a detailed analysis of case studies and real-world applications, the review highlights effective approaches and tools that enhance security, as well as emerging threats and future trends in container security. The ultimate goal is to equip practitioners and organizations with the knowledge to secure their Kubernetes environments effectively, ensuring robust defense mechanisms are in place against an evolving threat landscape.
