Guide to the Secure Configuration of Red Hat OpenShift Container Platform 4

with profile NIST National Checklist for Red Hat OpenShift Container Platform
This compliance profile reflects the core set of security related configuration settings for deployment of Red Hat OpenShift Container Platform into U.S. Defense, Intelligence, and Civilian agencies. Development partners and sponsors include the U.S. National Institute of Standards and Technology (NIST), U.S. Department of Defense, the National Security Agency, and Red Hat. This baseline implements configuration requirements from the following sources: - Committee on National Security Systems Instruction No. 1253 (CNSSI 1253) - NIST Controlled Unclassified Information (NIST 800-171) - NIST 800-53 control selections for Moderate-Impact systems (NIST 800-53) - U.S. Government Configuration Baseline (USGCB) - NIAP Protection Profile for General Purpose Operating Systems v4.2.1 (OSPP v4.2.1) - DISA Operating System Security Requirements Guide (OS SRG) For any differing configuration requirements, e.g. password lengths, the stricter security setting was chosen. Security Requirement Traceability Guides (RTMs) and sample System Security Configuration Guides are provided via the scap-security-guide-docs package. This profile reflects U.S. Government consensus content and is developed through the ComplianceAsCode initiative, championed by the National Security Agency. Except for differences in formatting to accommodate publishing processes, this profile mirrors ComplianceAsCode content as minor divergences, such as bugfixes, work through the consensus and release processes.
This guide presents a catalog of security-relevant configuration settings for Red Hat OpenShift Container Platform 4. It is a rendering of content structured in the eXtensible Configuration Checklist Description Format (XCCDF) in order to support security automation. The SCAP content is is available in the scap-security-guide package which is developed at https://www.open-scap.org/security-policies/scap-security-guide.

Providing system administrators with such guidance informs them how to securely configure systems under their control in a variety of network roles. Policy makers and baseline creators can use this catalog of settings, with its associated references to higher-level security control catalogs, in order to assist them in security baseline creation. This guide is a catalog, not a checklist, and satisfaction of every item is not likely to be possible or sensible in many operational scenarios. However, the XCCDF format enables granular selection and adjustment of settings, and their association with OVAL and OCIL content provides an automated checking capability. Transformations of this document, and its associated automated checking content, are capable of providing baselines that meet a diverse set of policy objectives. Some example XCCDF Profiles, which are selections of items that form checklists and can be used as baselines, are available with this guide. They can be processed, in an automated fashion, with tools that support the Security Content Automation Protocol (SCAP). The NIST National Checklist Program (NCP), which provides required settings for the United States Government, is one example of a baseline created from this guidance.
Do not attempt to implement any of the settings in this guide without first testing them in a non-operational environment. The creators of this guidance assume no responsibility whatsoever for its use by other parties, and makes no guarantees, expressed or implied, about its quality, reliability, or any other characteristic.

    Group   OpenShift Settings   Group contains 1 rule

    [ref]   Each section of this configuration guide includes information about the default configuration of an OpenShift cluster and a set of recommendations for hardening the configuration. For each hardening recommendation, information on how to implement the control and/or how to verify or audit the control is provided. In some cases, remediation information is also provided. Many of the settings in the hardening guide are in place by default. The audit information for these settings is provided in order to verify that the cluster admininstrator has not made changes that would be less secure than the OpenShift defaults. A small number of items require configuration. Finally, there are some recommendations that require decisions by the system operator, such as audit log size, retention, and related settings.

    Rule   The Identity Providers don't use the htpasswd-based authentication   [ref]

    TBD

    Warning:  This rule's check operates on the cluster configuration dump. Therefore, you need to use a tool that can query the OCP API, retreive the /apis/config.openshift.io/v1/oauths/cluster API endpoint to the local /kubernetes-api-resources/apis/config.openshift.io/v1/oauths/cluster file.
