StackRox Kubernetes Security Platform v4.1.1 releases

StackRox Kubernetes Security Platform

The StackRox Kubernetes Security Platform performs a risk analysis of the container environment, delivers visibility and runtime alerts, and provides recommendations to proactively improve security by hardening the environment. StackRox integrates with every stage of the container lifecycle: build, deploy, and runtime.

The StackRox Kubernetes Security platform is built on the foundation of the product formerly known as Prevent, which itself was called Mitigate and Apollo. You may find references to these previous names in the code or documentation.

Changelog v4.1

Added Features

  • Two new default permission sets Vulnerability Management Consumer and Vulnerability Management Admin have been added for vulnerability management.
    • Vulnerability Management Consumer provides read-only access to analyze vulnerabilities and initiate risk acceptance process.
    • Vulnerability Management Admin provides administrative access to analyze vulnerabilities, generate reports, and manage risk acceptance process.
  • A default role Network Graph Viewer has been added that provides sufficient privileges to display network graphs.
  • A new command roxctl central login has been added that allows to use a user’s token within roxctl instead of an API token or admin password.
  • ROX-15447: A new DelegatedRegistryConfig API at /v1/delegatedregistryconfig has been added that provides dynamic configuration for local registry scanning (replaces ROX_FORCE_LOCAL_IMAGE_SCANNING).
  • A new environment variable ROX_DISABLE_SIGNATURE_FETCHING has been added to Central and Sensor which stops fetching image signatures in case the signature verification feature shall not be used.
    You may set this in case there’s too much load on registries due to attempts to fetch image signatures.
    Note that if the environment variable is set, no signatures will be fetched and thus the signature verification feature cannot be used.
  • ROX-16532: Resource limits and requests for the node-inventory container can now be configured via the operator.
  • A new environment variable ROX_SCAN_TIMEOUT has been added to Sensor which allows for customizing the image scan timeout used in Sensor initiated scans.
  • ROX-17365: A new environment variable ROX_DELEGATED_SCANNING_DISABLED has been added that disables delegated scanning capabilities while leaving other local scanning capabilities intact.
  • ROX-16703: Helm setting scanner.disable=false now valid for any secured cluster (instead of OpenShift only). This enables scanner slim to be installed in non-OCP secured clusters.

Removed Features

  • ROX-14398: As announced in 3.74, the permission Access replaces the deprecated permission Role.
  • ROX-14398: As announced in 3.74, the Scope Manager system role and permission set will be removed. If existing product installations do have customer references to either the Scope Manager system role or the Scope Manager system permission set, then the referenced object will be adjusted to contain a description mentioning its deprecation. Furthermore, the objects will not be marked as system resources, and will not be supported anymore.
  • ROX-17031: env var ROX_FORCE_LOCAL_IMAGE_SCANNING has been removed and replaced by the DelegatedRegistryConfig API.
  • ROX-13888: As announced in 3.74, the permission WorkflowAdministration replaces the deprecated permissions Vulnerability Reports and Policy.
  • KernelModule collection has been removed, following deprecation in 4.0.
    • Secured clusters configured to use KernelModule collection will automatically switch to EBPF

Deprecated Features

  • Vulnerability Management 1.0 sections Image CVEs, Image Components, Images, Deployments, and Namespaces are deprecated and will be removed in the future. Once removed, use Vulnerability Management 2.0 for managing workload vulnerabilities.
  • Custom Security Context Constraints (SCC) (e.g.: stackrox-collectorstackrox-admission-controlstackrox-sensor) are deprecated and will be removed in the future.
    Users should ensure that those SCCs are not being used by workloads other than Stackrox/RHACS.
  • The default permission set Vulnerability Management Approver is deprecated and will be removed in a future release. Customers are advised to use Vulnerability Management Admin permission set instead. When Vulnerability Management Approver permission set is removed existing roles using it will be updated to use Vulnerability Management Admin.
  • The default permission set Vulnerability Management Requester is deprecated and will be removed in a future release. Customers are advised to use Vulnerability Management Consumer permission set instead. When Vulnerability Management Requester permission set is removed existing roles using it will be updated to use Vulnerability Management Consumer.
  • The default permission set Vulnerability Report Creator is deprecated and will be removed in a future release. Customers are advised to use Vulnerability Management Admin permission set instead. When Vulnerability Report Creator permission set is removed existing roles using it will be updated to use Vulnerability Management Admin.

Technical Changes

  • The Central PVC stackrox-db is no longer required after this upgrade. To obsolete existing PVC, please check the docs online.
  • The output of roxctl central whoami now includes the username as well.
  • Helm setting collector.nodeInventoryResources has been renamed to collector.nodeScanningResources.
  • ROX-16959: Helm setting admissionController.replicas has been added to configure admission controller replicas.
  • The file inside of (the file downloaded from for updating Scanner vulnerabilities in offline-mode)
    is no longer needed. We will continue to populate it to support older versions of the product, but it will be ignored.
  • The time interval used to determine the frequency to scan orchestrator-level components (Kubernetes, OpenShift, Istio) is now configurable
  • Image Integrations will now be synced with secured clusters that have local scanning enabled.
