Azure Kubernetes Sensitive Role Access

Sigma Rules

View Source
Summary
The Azure Kubernetes Sensitive Role Access detection rule monitors changes to ClusterRoles and Roles within Azure Kubernetes Service (AKS). It specifically targets operations related to writing, deleting, and escalating ClusterRoles and Roles by identifying the operation names associated with these actions in Azure activity logs. Changes to these RBAC components can indicate potential malicious behavior such as privilege escalation or unauthorized access, which could lead to serious security risks in a Kubernetes environment. By observing these operations, security teams can respond promptly to suspicious activities, enforce security policies, and ensure compliance with best practices for Kubernetes RBAC management. Properly configuring alerts for this rule will help safeguard sensitive role access and maintain the security posture of the Kubernetes cluster.
