Kubernetes dashboards provide a visual interface to manage and monitor the cluster, making them powerful tools for cluster administration. However, if not properly secured, they can expose sensitive information and grant unauthorized access, leading to significant security risks.
Exposure of Sensitive Data: Dashboards can display critical information such as cluster configurations, service endpoints, secrets, logs, and metrics. If this information is accessed by unauthorized users, it can be exploited for malicious activities such as data theft, service disruption, or privilege escalation.
Unauthorized Access: Without proper access controls, unauthorized users could view or manipulate cluster components. This could lead to data breaches, unintentional changes, or a full compromise of the cluster’s resources and functionalities.
Cluster Administration Risk: Many dashboards allow users to perform administrative actions that can alter the state of the cluster. Unauthorized access to these features could result in catastrophic changes to the cluster’s configuration or even a complete takeover.
To mitigate these risks, strict security measures must be applied to Kubernetes dashboards.
