Chapter 5. Security considerations

5.1. FIPS-140-2

The Federal Information Processing Standard Publication 140-2 (FIPS-140-2) is a standard defining a set of security requirements for the use of cryptographic modules. This standard is mandated by law for US government agencies and contractors and is also referenced in other international and industry specific standards.

Red Hat OpenShift Container Storage is now using FIPS validated cryptographic modules as delivered by Red Hat Enterprise Linux OS/CoreOS (RHCOS).

The cryptography modules are currently being processed by Cryptographic Module Validation Program (CMVP) and their state can be seen at Modules in Process List. For more up-to-date information, see the knowledge base article.


FIPS mode must be enabled on the OpenShift Container Platform, prior to installing OpenShift Container Storage. OpenShift Container Platform must run on RHCOS nodes, as OpenShift Container Storage deployment on RHEL 7 is not supported for this feature.

For more information, see installing a cluster in FIPS mode and support for FIPS cryptography.

5.2. Proxy environment

A proxy environment is a production environment that denies direct access to the internet and provides an available HTTP or HTTPS proxy instead. Red Hat Openshift Container Platform is configured to use a proxy by modifying the proxy object for existing clusters or by configuring the proxy settings in the install-config.yaml file for new clusters.

Red Hat supports deployment of Openshift Container Storage versions 4.5 and higher in proxy environments when OpenShift Container Platform has been configured according to configuring the cluster-wide proxy.
