Description

In RHACS, runtime policies configured with the AUDIT_LOG_EVENT source do not allow custom Kubernetes resources. They are strictly set to a set of Kubernetes resource types: ConfigMaps, Secrets,
ClusterRoles, ClusterRoleBindings, NetworkPolicies, SecurityContextConstraints, EgressFirewalls.

This PR adds a Kubernetes API Resource option (<plural>[.<group>], e.g. applications.argoproj.io) so policies can target any resource, including CRDs.

The existing Kubernetes Resource Type is unchanged so we can still use the enum with default types.

User-facing documentation

Gated by ROX_AUDIT_LOG_CUSTOM_RESOURCES (off by default).

Testing and quality

  • the change is production ready: the change is GA, or otherwise the functionality is gated by a feature flag
  • CI results are inspected

Automated testing

  • added unit tests
  • added e2e tests
  • added regression tests
  • added compatibility tests
  • modified existing tests

How I validated my change

See screenshots. I validated both policies with the shorthand form: limitranges and with a group: routes.route.openshift.io

Add api_group/api_resource to audit events, a CUSTOM alert resource
type with api_resource, requested API resources in the audit log start
request, and the ROX_AUDIT_LOG_CUSTOM_RESOURCES flag.
Forward audit events for requested <plural>[.<group>] resources on top
of the unchanged built-in set. Subresources and GET/LIST/WATCH are
skipped for these.
Audit log sections need either Kubernetes Resource or Kubernetes API
Resource, not both. Built-in resources, regexes and negation are
rejected. Central rejects the field while the flag is disabled.
Sensor derives the resources from enabled audit log policies and
restarts collection when they change.
Events for non-enum resources become CUSTOM alerts with a searchable
api_resource, which is also compared when merging alerts.
Add the criterion behind the feature flag and show the API resource
for CUSTOM violations.
Test a policy on limitranges when the feature flag is enabled.
Audit events use plural resource names, so point to api-resources.

Hi @zwennesm. Thanks for your PR.

I'm waiting for a stackrox member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Audit log policies can target custom Kubernetes API resources by plural name, optionally qualified by API group, when the feature is enabled.
    • Audit log collection includes custom resources selected by enabled policies.
    • Custom-resource alerts display the resource name in alert details, violation lists, and notifications.
  • Bug Fixes
    • Alerts for custom resources match the correct API resource, preventing mix-ups between resources with the same name in different API groups.
    • Cluster-scoped custom-resource alerts are handled without a namespace lookup.

Walkthrough

This change adds a Kubernetes API Resource criterion for audit-log policies. It passes selected resources to audit-log collection and carries custom resource identities through event processing, alert storage, matching, and presentation.

Merge Risk: 🔵 Low · up to 8dcd9

Blank custom-resource values can cause policy saves to fail, and some dashboards and notifications hide the resource kind. These are limited usability gaps in the new feature and merit owner awareness or follow-up.

🟡 Minor · Reject empty Kubernetes API Resource values before submission. · policyCriteriaValidators.ts:26-59

ui/apps/platform/src/Containers/Policies/Wizard/Step3/policyCriteriaValidators.ts:26-59
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Reject empty Kubernetes API Resource values before submission.

Step 3 requires a value object, but it does not validate values[].value. The field validator also accepts empty or whitespace-only input. The conversion path preserves the raw value, so createPolicy or savePolicy can submit it. Backend validation then rejects the API resource, and the policy save fails.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Preserve ApiResource in notification payloads.

When ApiResource is non-empty, ToAlertResource sets ResourceType to CUSTOM but preserves the canonical value separately. Teams, PagerDuty, AWS Security Hub, and CSCC formatters use only the resource type or resource name. Their payloads therefore expose CUSTOM or omit the resource kind, so recipients cannot identify the custom resource type. The common pkg/notifiers/format.go formatter already emits API Resource; update these channel-specific formatters to use that shared identity formatting, or add equivalent ApiResource fields to each payload.

Preserve the canonical API resource in the recent-violations widget.

The dashboard query omits resource.apiResource. The widget then renders the resource name with a ResourceIcon whose title is always CustomResource. Add apiResource to the query and render it as a separate custom-resource type label in MostRecentViolations.tsx. Keep CustomResource as the icon kind.
