+title: 'Restrict Create/Modify Virtual Machine Cluster Instance and Preference Types'
+
+description: |-
+    Because the set of authorized subjects is specific to each environment,
+    this rule requires manual verification. Organizations can create a
+    CustomRule using CEL to automate this check by evaluating
+    ClusterRoleBindings and ClusterRoles for create and update access to
+    <tt>virtualmachineclusterinstancetypes</tt> and
+    <tt>virtualmachineclusterpreferences</tt> resources, verifying that
+    only approved subjects are bound to those permissions.
+
+rationale: |-
+    Cluster instance types and preferences govern the default hardware
+    and configuration settings applied to new virtual machines. If
+    unauthorized subjects can create or modify these resources, they
+    can introduce overly permissive settings, disable security
+    controls, or allocate excessive resources across the cluster.
+    Restricting access ensures that only approved administrators
+    define the VM profiles available to tenants.

+    Run the following commands to check which subjects can create or
+    update cluster instance and preference types:
+    <pre>$ oc adm policy who-can create virtualmachineclusterinstancetypes</pre>
+    <pre>$ oc adm policy who-can update virtualmachineclusterinstancetypes</pre>
+    <pre>$ oc adm policy who-can create virtualmachineclusterpreferences</pre>
+    <pre>$ oc adm policy who-can update virtualmachineclusterpreferences</pre>
+    Verify that only authorized subjects are listed in the output.
