In this episode of DevOps Daily with Fexingo, Lucas and Luna explore a common but overlooked security risk in Kubernetes: overly permissive Role-Based Access Control (RBAC) configurations. They start with a real-world example from a mid-size fintech that suffered a breach because a service account had cluster-admin privileges. They break down why default roles like 'cluster-admin' and 'edit' are often too broad, how horizontal privilege escalation works in practice, and why many teams treat RBAC as a checkbox exercise. The hosts walk through the principle of least privilege, contrast Role vs ClusterRole, and explain what a proper RBAC audit looks like. They also discuss how to use tools like kubectl auth can-i and third-party scanners to identify overprivileged accounts. By the end, listeners understand why RBAC misconfigurations are a top attack vector and how to fix them before an audit or incident. #Kubernetes #RBAC #CloudSecurity #DevOps #K8sSecurity #PrivilegeEscalation #LeastPrivilege #ServiceAccount #ClusterAdmin #Kubectl #TechPodcast #Technology #FexingoBusiness #BusinessPodcast #SoftwareOperations #CICD #PodSecurity #AccessControl Keep every episode free: buymeacoffee.com/fexingo
