Configure the Audit Log Path
To enable auditing on the OpenShift API Server, the audit log path must be set. Edit the <code>openshift-apiserver</code> configmap and set the <code>audit-log-path</code> to a suitable path and fi...Rule High Severity -
Role-based Access Control
Role-based access control (RBAC) objects determine whether a user is allowed to perform a given action within a project. Cluster administrators can use the cluster roles and bindings to control wh...Group -
Ensure cluster roles are defined in the cluster
<p> RBAC is a critical feature in terms of security for Kubernetes and OpenShift. It enables administrators to segment the privileges granted to a service account, and thus allows us...Rule Medium Severity -
Profiling is protected by RBAC
Ensure that the cluster-debugger cluster role includes the /debug/pprof resource URL. This demonstrates that profiling is protected by RBAC, with a specific cluster role to allow access.Rule Medium Severity -
Ensure that the RBAC setup follows the principle of least privilege
Role-based access control (RBAC) objects determine whether a user is allowed to perform a given action within a project. If users or groups exist that are bound to roles they must not have, modify...Rule High Severity -
Ensure that the cluster-admin role is only used where required
The RBAC role cluster-admin provides wide-ranging powers over the environment and should be used only where and when needed.Rule Medium Severity -
Limit Access to Kubernetes Secrets
The Kubernetes API stores secrets, which may be service account tokens for the Kubernetes API or credentials used by workloads in the cluster. Access to these secrets should be restricted to the sm...Rule Medium Severity -
Ensure that the ClusterLogging and ClusterLoggingForwarder resources are protected from unauthorized deletion
The ClusterLogging and ClusterLoggingForwarder Custom Resources provide a way to configure the logging forwarding subsystem and delete access to it should be restricted to as-needed basis. Remove...Rule Medium Severity -
Ensure that the ClusterLogging and ClusterLoggingForwarder resources are protected from unauthorized modification
The ClusterLogging and ClusterLoggingForwarder Custom Resources provide a way to configure the logging forwarding subsystem and modification access to it should be restricted to as-needed basis. ...Rule Medium Severity -
Ensure that the ClusterLogging and ClusterLoggingForwarder resources are protected from unauthorized access
The ClusterLogging and ClusterLoggingForwarder Custom Resources provide a way to configure the logging forwarding subsystem and view access to it should be restricted to as-needed basis. Remove v...Rule Medium Severity -
Minimize Access to Pod Creation
The ability to create pods in a namespace can provide a number of opportunities for privilege escalation. Where applicable, remove <code>create</code> access to <code>pod</code> objects in the clus...Rule Medium Severity -
Minimize Wildcard Usage in Cluster and Local Roles
Kubernetes Cluster and Local Roles provide access to resources based on sets of objects and actions that can be taken on those objects. It is possible to set either of these using a wildcard <code>...Rule Medium Severity -
Kubernetes - Registry Security Practices
Contains evaluations for Kubernetes registry security practices, and cluster-wide registry configuration.Group -
Limit Access to the Host IPC Namespace
Containers should not be allowed access to the host's Interprocess Communication (IPC) namespace. To prevent containers from getting access to a host's IPC namespace, the appropriate Security Conte...Rule Medium Severity -
All configured ImageStreams are configured to periodically check for updates
<p> The configuration <code>imagestream.spec.tags.importPolicy.scheduled</code> determines whether the imagestream is configured to periodically check for updates. This is useful whe...Rule Medium Severity -
Allowed registries are configured
The configuration <code>registrySources.allowedRegistries</code> determines the permitted registries that the OpenShift container runtime can access for builds and pods. This configuration setting ...Rule Medium Severity -
Allowed registries for import are configured
The configuration <code>allowedRegistriesForImport</code> limits the container image registries from which normal users may import images. This is important to control, as a user who can stand up a...Rule Medium Severity -
Check configured allowed registries for import uses secure protocol
The configuration <code>allowedRegistriesForImport</code> limits the container image registries from which normal users may import images. This is a list of the registries that can be trusted to co...Rule Medium Severity -
Check if any insecure registry sources is configured
The configuration <code>registrySources.insecureRegistries</code> determines the insecure registries that the OpenShift container runtime can access for builds and pods. This configuration setting ...Rule Medium Severity -
