Role-based access control in OCP IBM Cloud

Summary and Key concepts

Summary:

This article introduces the security features of Portworx, focusing on Role-based Access Control (RBAC) and volume encryption. Portworx RBAC manages access control across the cluster, defining authentication, authorization, and ownership. It also supports cluster-wide encryption and more granular namespace or storage-class level encryption for Persistent Volume Claims (PVCs). The article includes references to more detailed guides on creating encrypted PVCs for platforms where Portworx is deployed.

Kubernetes Concepts:

• Persistent Volume Claims (PVC)

Portworx Concepts:

• Volume Encryption

PX-Security is an important set of features of the Portworx platform that provide:

• Role-based access control (RBAC) for authorization, authentication, and ownership
• Cluster-wide volume encryption
• Namespace-granular or Storage-class BYOK volume encryption

This section describes the role-based access control (RBAC) model used by Portworx. For details on volume encryption, see create encrypted PVCs.
