Scheduling compliance scans and assessing profile compliance (Technology preview)

Scheduling compliance scans and assessing profile compliance is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

You can create and manage compliance scan schedules on the schedules page that meet your operational needs. You can only have one schedule that scans the same profile on the same cluster.

By viewing and filtering the scan results on the coverage page, you can monitor the compliance status across all clusters.

Customizing and automating your compliance scans

By creating a compliance scan schedule, you can customize and automate your compliance scans to align with your operational requirements.

You can only have one schedule that scans the same profile on the same cluster. This means that you cannot create multiple scan schedules for the same profile on a single cluster.
Prerequisites

  • You have installed the Compliance Operator.

    For more information about how to install the Compliance Operator, see "Using the Compliance Operator with Red Hat Advanced Cluster Security for Kubernetes".

    • Currently, the compliance feature and the Compliance Operator evaluate only infrastructure and platform compliance.

    • The compliance feature requires the Compliance Operator to be running and does not support Amazon Elastic Kubernetes Service (EKS).

Coverage page overview

When you view the coverage page and apply a filter to a schedule, all results are filtered accordingly. This filter remains active for all coverage pages until you delete it. You can always view the results based on a single profile.

You can select profiles grouped according to their associated benchmarks by using the toggle group. You calculate the compliance percentage based on the number of passed checks in relation to the total number of checks.

The Checks view lists the profile checks and enables you to easily navigate and understand your compliance status.

The profile check information is organized into the following groups:

  • Check: The name of the profile check.

  • Controls: Shows the various controls associated with each check.

  • Fail status: Shows the checks that have failed and require your attention.

  • Pass status: Shows the checks that have been successfully passed.

  • Manual status: Shows the checks that require a manual review because additional organizational or technical knowledge is required that you cannot automate.

  • Other status: Shows the checks with a status other than pass or fail, such as warnings or informational statuses.

  • Compliance: Shows the overall compliance status and helps you to ensure that your environment meets the required standards.

The Clusters view lists the clusters and enables you to effectively monitor and manage your clusters.

The cluster information is organized into the following groups:

  • Cluster: The name of the cluster.

  • Last scanned: Indicates when the individual clusters were last scanned.

  • Fail status: Shows the clusters whose scan has failed and which require your attention.

  • Pass status: Shows the clusters that have successfully passed all checks.

  • Manual status: Shows the checks that require a manual review because additional organizational or technical knowledge is required that you cannot automate.

  • Other status: Shows the clusters that have a status other than pass or fail, such as warnings or informational alerts.

  • Compliance: Shows the overall compliance status of your clusters and helps you to ensure that they meet the required standards.

Monitoring and analyzing the health of your clusters
