Chapter 3. Managing compliance 3.1. Compliance feature overview The compliance feature ensures that your Kubernetes clusters adhere to industry standards and regulatory requirements. It provides automated compliance checks that enable you to continuously monitor your clusters against predefined benchmarks such as CIS, PCI-DSS, HIPAA, and so on. The feature includes detailed reports and remediation guidance to help administrators quickly identify and resolve compliance issues. You can view the compliance results associated with your cluster by using the compliance feature in the Red Hat Advanced Cluster Security for Kubernetes (RHACS) portal. The compliance feature summarizes information into the following sections: Dashboard , formerly known as Compliance 1.0 , summarizes the compliance information collected from all your clusters. It covers workload and infrastructure compliance. Important By running a compliance scan in RHACS, you can monitor the entire Kubernetes infrastructure and workloads and ensure that they meet the required standards. You can use the compliance dashboard for filtering and detailed reporting. For more information, see Monitoring workload and cluster compliance . Schedules and Coverage (Tech preview) , formerly known as Compliance 2.0 , summarizes the compliance information in a single interface after the scheduled scans by using the Compliance Operator. Important If you have Red Hat OpenShift clusters with the Compliance Operator installed, you can create and manage compliance scan schedules directly in RHACS on the schedules page. The coverage page shows you the scan results associated with a benchmark and profile in a single interface. For more information, see Scheduling compliance scans and assessing profile compliance (Technology preview) . 3.1.1. Compliance assessment and reporting by using RHACS On the dashboard page, you can assess and report on the compliance of your containerized infrastructure and workloads with the applicable technical controls from a range of security and regulatory frameworks. You can run out-of-the-box compliance scans based on the following industry standards: Center for Internet Security (CIS) Benchmarks for Kubernetes Health Insurance Portability and Accountability Act (HIPAA) National Institute of Standards and Technology (NIST) Special Publication 800-190 NIST Special Publication 800-53 Payment Card Industry Data Security Standard (PCI DSS) OpenShift Compliance Operator Profiles : The Compliance Operator evaluates the compliance of both the OpenShift Container Platform Kubernetes API resources and the nodes running the cluster. There are several profiles available as part of the Compliance Operator installation. For more information about the available profiles, see Supported compliance profiles . By scanning your environment based on these standards, you can: Evaluate your infrastructure for regulatory compliance. Harden your Kubernetes orchestrator. Understand and manage the overall security posture of your environment. Get a detailed overview of the compliance status of clusters, namespaces, and nodes. 3.2. Monitoring workload and cluster compliance By performing compliance scans, you can check the compliance status of your entire infrastructure in RHACS. You can view the results in the compliance dashboard, where you can filter data and monitor compliance status across clusters, namespaces and nodes. By generating detailed compliance reports and focusing on specific standards, controls and industry benchmarks, you can track and share the compliance status of your environment, and ensure that your infrastructure meets the required compliance standards. 3.2.1. Checking the compliance status of your infrastructure By performing a compliance scan, you can check the compliance status of your entire infrastructure for all compliance standards. When you run a compliance scan, Red Hat Advanced Cluster Security for Kubernetes (RHACS) creates a data snapshot of your environment. The data snapshot includes alerts, images, network policies, deployments, and related host-based data. Central collects the host-based data from Sensors running in your clusters. Central then collects further data from the compliance container running in each Collector pod. The compliance container collects the following data about your environment: Configurations for the container daemon, container runtime and container image. Information about container networks. Command-line arguments and processes for the container runtime, Kubernetes, and OpenShift Container Platform. Permissions for specific file paths. Configuration files for Kubernetes and OpenShift Container Platform core services. After data collection is complete, Central checks the data to determine the results. You can view the results in the compliance dashboard and create compliance reports based on the results. Note The following terms are associated with a compliance scan: Control describes a single line item in an industry or regulatory standard that an auditor uses to evaluate an information system for compliance with that standard. RHACS verifies evidence of compliance with a single control by performing one or more checks. Check is the single test performed during a single control assessment. Some controls have multiple checks associated with them. If one of the associated checks for a control fails, the entire control state is marked as Fail. Procedure In the RHACS portal, click Compliance Dashboard . Optional: By default, information on all standards is displayed in the compliance results. To display information about specific standards only, perform the following steps: Click Manage standards . By default, all standards are selected. Clear the checkbox for any specific standard that you do not want to display. Click Save . Standards that are not selected do not appear in the dashboard display, including the widgets, in the compliance results tables accessible from the dashboard, and in the PDF files created by using the Export button. However, when exporting the results as a CSV file, all default standards are included. Click Scan environment . Note Scanning the entire environment takes about 2 minutes to complete. This time might vary depending on the number of clusters and nodes in your environment. Verification In the RHACS portal, click Configuration Management . In the CIS Kubernetes v1.5 widget, click Scan . RHACS displays a message which indicates that a compliance scan is in progress. 3.2.2. Viewing the compliance standards across your environment The compliance dashboard gives you an overview of the compliance standards in all clusters, namespaces, and nodes in your environment, including charts and options to investigate potential compliance issues.
