In the dynamic world of container orchestration, Kubernetes (K8s) stands as a beacon of efficiency. However, the ease of managing and deploying applications comes with security challenges, particularly in access control. Role-Based Access Control (RBAC) alone is not enough to secure access to your K8s, especially when managing sensitive data or "secrets."
The heart of the matter is, RBAC operates within a predefined scope of rules which, while useful, might not suffice in the face of evolving security threats and complex, dynamic Kubernetes environments. Moreover, the management of sensitive information, known as secrets, intertwines with RBAC, adding another layer of complexity to the security narrative.
Let’s unravel why RBAC might not be enough to solve your Kubernetes access control challenges, and what you should be doing instead.
