Rules, Groups, and Values defined within the XCCDF Benchmark

  • OCP version yaml path

    When scanning OpenShift clusters, not all type of cluster has same api resource path for ocp version, ex. HyperShift OCP version api resource path is different than a regular OpenShift Cluster. Thi...

  • System and Software Integrity

    System and software integrity can be gained by installing antivirus, increasing system encryption strength with FIPS, verifying installed software, enabling SELinux, installing an Intrusion Prevent...

  • Ensure that Cluster Version Operator is deployed

    Integrity of the OpenShift platform is handled to start by the cluster version operator. Cluster Version Operator will by default GPG verify the integrity of the release image before applying it. ...

  • Ensure that the MachineSets provisioned by Azure have disk encryption enabled

    OpenShift has an option to provide the Disk Encryption Set [1] when deploying nodes on Azure. This enabled disk encryption and ensures that the OpenShift nodes have that enabled. [1] https://docs....
    Rule High Severity
  • Ensure that EBS volumes use by cluster nodes are encrypted

    OpenShift MachineSets can be configured to enable EBS encryption on EBS storage used by cluster nodes. By using EBS encryption, disk contents are encrypted using a AWS KMS key.
    Rule High Severity
  • Ensure that FIPS mode is enabled on all cluster nodes

    OpenShift has an installation-time flag that can enable FIPS mode for the cluster. The flag
    fips: true
    must be enabled at install time in the
    install-config.yaml
    file.
