Roles-based Access Control

This section describes the permissions required to use the rancher-cis-benchmark App.

The rancher-cis-benchmark is a cluster-admin only feature by default.

However, the rancher-cis-benchmark chart installs these two default ClusterRoles:

  • cis-admin
  • cis-view

In Rancher, only cluster owners and global administrators have cis-admin access by default.

Note: If you were using the cis-edit role added in Rancher v2.5 setup, it has now been removed since Rancher v2.5.2 because it essentially is same as cis-admin. If you happen to create any clusterrolebindings for cis-edit, please update them to use cis-admin ClusterRole instead.

Cluster-Admin Access​

Rancher CIS Scans is a cluster-admin only feature by default. This means only the Rancher global admins, and the cluster’s cluster-owner can:

  • Install/Uninstall the rancher-cis-benchmark App
  • See the navigation links for CIS Benchmark CRDs - ClusterScanBenchmarks, ClusterScanProfiles, ClusterScans
  • List the default ClusterScanBenchmarks and ClusterScanProfiles
  • Create/Edit/Delete new ClusterScanProfiles
  • Create/Edit/Delete a new ClusterScan to run the CIS scan on the cluster
  • View and Download the ClusterScanReport created after the ClusterScan is complete

Summary of Default Permissions for Kubernetes Default Roles​

The rancher-cis-benchmark creates three ClusterRoles and adds the CIS Benchmark CRD access to the following default K8s ClusterRoles:

ClusterRole created by chartDefault K8s ClusterRolePermissions given with Role
cis-adminadminAbility to CRUD clusterscanbenchmarks, clusterscanprofiles, clusterscans, clusterscanreports CR
cis-viewview Ability to List(R) clusterscanbenchmarks, clusterscanprofiles, clusterscans, clusterscanreports CR

By default only cluster-owner role will have ability to manage and use rancher-cis-benchmark feature.

The other Rancher roles (cluster-member, project-owner, project-member) do not have any default permissions to manage and use rancher-cis-benchmark resources.

But if a cluster-owner wants to delegate access to other users, they can do so by creating ClusterRoleBindings between these users and the above CIS ClusterRoles manually. There is no automatic role aggregation supported for the rancher-cis-benchmark ClusterRoles.
