Security for Red Hat OpenShift on IBM Cloud 

You can use built-in security features in Red Hat® OpenShift® on IBM Cloud® for risk analysis and security protection. These features help you to protect your cluster infrastructure and network communication, isolate your compute resources, and ensure security compliance across your infrastructure components and container deployments.



 Overview of security threats for your cluster 

To protect your cluster from being compromised, you must understand potential security threats for your cluster and what you can do to reduce the exposure to vulnerabilities.

External attacks
: Attackers that gain access to your cluster, deployed resources, apps, or personal information.

Vulnerable deployments
: Known vulnerabilities are exploited to gain access to the cloud environment and run malicious software.

Compromised or lost data
: Incorrect storage of sensitive data and missing encryption.

Insiders and third party vendors
: Missing network isolation and segmentation can lead to the misuse of legitimate permissions.

Cloud security and the protection of your systems, infrastructure, and data against attacks became very important over the last couple of years as companies continue to move their workloads into the public cloud. A cluster consists of several components that each can put your environment at risk for malicious attacks. To protect your cluster against these security threats, you must make sure that you apply the latest Red Hat OpenShift on IBM Cloud, Red Hat OpenShift, and Kubernetes security features and updates in all cluster components.

These components include:



* [Red Hat OpenShift API server and etcd data store](https://cloud.ibm.com/docs/openshift?topic=openshift-securityapiserver)
* [Worker nodes](https://cloud.ibm.com/docs/openshift?topic=openshift-securityworkernodes)
* [Network](https://cloud.ibm.com/docs/openshift?topic=openshift-securitynetwork)
* [Persistent storage](https://cloud.ibm.com/docs/openshift?topic=openshift-securitystorage)
4.6 version information and update actions 

Version 4.6 is unsupported.

Review information about version 4.6 of Red Hat OpenShift on IBM Cloud, released 09 Jun 2021. This version is based on Kubernetes version 1.19.

 Preparing to update 

Review changes that you might need to make when you [update a cluster](https://cloud.ibm.com/docs/openshift?topic=openshift-update) to version 4.6.
Kubernetes alpha features, which are subject to change, are generally not enabled by default. With Kubernetes, you can combine various resources such as secrets, deployments, and services to securely create and manage highly available, containerized apps.

Red Hat OpenShift
: Red Hat OpenShift on IBM Cloud is a Kubernetes-based platform that is designed especially to accelerate your containerized app delivery processes that run on a Red Hat Enterprise Linux 7 operating system. You can orchestrate and scale your existing Red Hat OpenShift workloads across on-prem and off-prem clouds for a portable, hybrid solution that works the same in multicloud scenarios. To get started, try out the [Red Hat OpenShift on IBM Cloud tutorial](https://cloud.ibm.com/docs/openshift?topic=openshift-openshift_tutorial).
* Does the service come with a managed Kubernetes master and worker nodes?

Every cluster in IBM Cloud Kubernetes Service is controlled by a dedicated Kubernetes master that is managed by IBM in an IBM-owned IBM Cloud infrastructure account. The Kubernetes master, including all the master components, compute, networking, and storage resources, is continuously monitored by IBM Site Reliability Engineers (SREs). The SREs apply the latest security standards, detect and remediate malicious activities, and work to ensure reliability and availability of IBM Cloud Kubernetes Service. Add-ons, such as Fluentd for logging, that are installed automatically when you provision the cluster are automatically updated by IBM. However, you can choose to disable automatic updates for some add-ons and manually update them separately from the master and worker nodes. For more information, see [Updating cluster add-ons](https://cloud.ibm.com/docs/containers?topic=containers-updateaddons).

Periodically, Kubernetes releases [major, minor, or patch updates](https://cloud.ibm.com/docs/containers?topic=containers-cs_versionsupdate_types). These updates can affect the Kubernetes API server version or other components in your Kubernetes master.

Setting up the Red Hat Marketplace 

Virtual Private Cloud

Classic infrastructure

Satellite

With [Red Hat® Marketplace](https://marketplace.redhat.com/en-us), you can deploy certified Red Hat software from an operator-based catalog to your OpenShift Container Platform clusters, including Red Hat® OpenShift® on IBM Cloud®.

Required permissions:



* The IAM Operator platform access role for the cluster in Kubernetes Service.
* The IAM Manager service access role in all namespaces (cluster-admin RBAC) for the cluster in Kubernetes Service.



Red Hat Marketplace is available for clusters that run Red Hat OpenShift version 4 only.

Before you begin:



* Register for a [Red Hat Marketplace account](https://marketplace.redhat.com/en-us/registration/redhat-marketplace).
* [Access your Red Hat OpenShift cluster](https://cloud.ibm.com/docs/openshift?topic=openshift-access_cluster).
* Make sure that the Operator Lifecycle Manager (OLM) pods in the openshift-operator-lifecycle-manager project and marketplace pods in the openshift-marketplace project are ready and running. You might have to restart a pod to return the pod to a healthy state.

oc get pods -n openshift-operator-lifecycle-manager

oc get pods -n openshift-marketplace



To set up your cluster with Red Hat Marketplace:



1. Follow the [Red Hat Marketplace instructions](https://marketplace.redhat.com/en-us/workspace/clusters/add/register) to create a namespace, operator, and global pull secret for the Red Hat Marketplace.
2. Verify that the global pull secret for the cluster is updated with the registry.marketplace.redhat.com secret.

oc get secret pull-secret -n openshift-config --output="jsonpath={.data..dockerconfigjson}" | base64 --decode | grep "marketplace" -A4

 14 June 2023 

New! Red Hat OpenShift on IBM Cloud 4.13
: You can create or [update clusters to version 4.13](https://cloud.ibm.com/docs/openshift?topic=openshift-openshift_changelog_413). With Red Hat OpenShift on IBM Cloud version 4.13, you get the latest features, as well as component updates on Red Hat OpenShift on IBM Cloud.

New! Red Hat OpenShift console access for cluster version 4.13
: For clusters that run version 4.13, the Red Hat OpenShift console is accessible via the virtual private endpoint (VPE) gateway URL. For more information, see [Accessing VPC clusters through the VPE gateway](https://cloud.ibm.com/docs/containers?topic=containers-access_clustervpc_vpe).

Master fix pack and worker node fix pack update
: Red Hat OpenShift on IBM Cloud [master fix pack 4.13.0_1522_openshift and worker node fix pack 4.13.1_1521_openshift](https://cloud.ibm.com/docs/openshift?topic=openshift-openshift_changelog_413) are available.

Remote health monitoring
: Red Hat OpenShift on IBM Cloud clusters are connected to [remote health monitoring](https://docs.openshift.com/container-platform/4.13/support/remote_health_monitoring/about-remote-health-monitoring.html) by default. This means clusters report health and usage data to Red Hat unless you opt out. With connected clusters, IBM Cloud is better positioned to support customers when there are issues specific to Red Hat which impact them.
