Kubernetes, a leading platform for managing containerized applications, presents unique challenges in access control and security due to its distributed nature. Organizations must balance developer freedom with governance to prevent unauthorized access, data breaches, and resource conflicts. Effective management requires a deep understanding of Kubernetes' architecture, implementing best practices like Role-Based Access Control (RBAC), namespace isolation, and network policies, and using tools such as Komodor, which simplifies these processes. Komodor enhances access control with single sign-on, granular RBAC, audit logging, and configuration scanning, aligning with security best practices to maintain a secure Kubernetes environment. These measures are crucial as inadequate controls can lead to security incidents and operational disruptions, impacting reliability and performance.
