The "Role-Based Access Control (RBAC) Good Practices" guide offers essential principles for securely managing access in Kubernetes clusters. It emphasizes the importance of the least privilege, ensuring that users and workloads have only the necessary permissions to perform their roles. Key recommendations include assigning permissions at the namespace level, avoiding overly broad or wildcard permissions, and minimizing the use of privileged tokens.
The guide also highlights potential risks, such as privilege escalation and denial of service (DoS) attacks, which can arise from improperly configured RBAC policies. Specific actions, like granting the "escalate," "bind," or "impersonate" privileges, require careful consideration to prevent unauthorized access. Additionally, it advises cluster operators to regularly review and harden RBAC settings, removing unnecessary permissions and implementing resource quotas to mitigate DoS risks.
Overall, this guide provides a concise framework for securely implementing RBAC in Kubernetes, helping to protect clusters from security incidents by ensuring that access is appropriately restricted and continuously monitored.
