Announcing the integration of Red Hat OpenShift on IBM Cloud and IBM Cloud Kubernetes Service with IBM Cloud Hyper Protect Crypto Services.

Moving confidential data and workloads to the cloud brings up challenges with ensuring the right security controls are in place to protect the data. Customers want to ensure that their data and IP are safe from both internal and external threats. IBM recently announced industry-leading security capabilities to enable enterprise customers who are looking to store highly sensitive data in the public cloud.

The industry’s highest level of encryption key protection is now available for IBM Cloud Kubernetes Service and Red Hat OpenShift on IBM Cloud through integration with IBM Cloud Hyper Protect Crypto Services.

What is IBM Cloud Hyper Protect Crypto Services?

IBM Cloud Hyper Protect Crypto Services is a single-tenant Key Management Service and a Cloud Hardware Security Module (HSM) service. Key vaulting is provided by dedicated, customer-controlled cloud HSMs that are built on FIPS 140-2 Level 4-certified (tamper-proof) hardware, the highest offered by any cloud provider in the industry. The service offers Keep Your Own Key (KYOK) capabilities, which allow customers to have exclusive key control— only authorized users have access (no privileged users, including IBM Cloud admins, have access) to encryption keys.

What is Red Hat OpenShift on IBM Cloud?

Red Hat OpenShift on IBM Cloud is a managed service that simplifies deployment and configuration of the OpenShift Container Platform. As a managed service, IBM will automate initial provisioning as well as ongoing maintenance, including operating system patches, vulnerability remediation, and any updates in the OpenShift stack. 

What is the IBM Cloud Kubernetes Service?

IBM Cloud Kubernetes Service is a managed container service offering that leverages Kubernetes as the container orchestration solution. It delivers powerful management tools, an intuitive user experience, and built-in security and isolation to enable rapid delivery of applications, all while leveraging Cloud Services and cognitive capabilities from Watson. As a certified CNCF K8s provider, IBM Cloud Kubernetes Service provides native Kubernetes capabilities like intelligent scheduling, self-healing, horizontal scaling, service discovery and load balancing, automated rollouts and rollbacks, and secret and configuration management.

Protecting sensitive data in applications

When it comes to cloud native applications built with Kubernetes, data protection should cover both Kubernetes secrets and the persistent datastores used by the apps. IBM Cloud Kubernetes Service already provides support for Bring Your Own Key (BYOK) through integration with IBM Key Protect. Key Protect is a multi-tenant service with key vaulting provided by IBM-controlled, FIPS 140-2 Level 3 certified Hardware Security Modules (HSM).

Exclusive key control with KYOK

Customers looking to safeguard highly sensitive data want to use their own keys for encryption and also require complete control of their encryption keys. For these customers, Hyper Protect Crypto Services provides exclusive control over the entire key hierarchy, including the master key of the HSM that protects the secrets. The Level-4 certification assures that the HSM is tamper-proof—it can sense any attempt to compromise the HSM via physical, chemical, or environmental changes and immediately responds by auto-erasing the keys stored, which then invalidates the data that the keys protect.

  • Kubernetes secrets: A secret is an object that stores sensitive data like a password, a token, or a key. There are built-in secrets that are created automatically by Kubernetes, such as the secret containing credentials for access the API endpoint. There are also user-created secrets, such as storing access information to leverage other IBM Cloud services, including Watson and IBM Cloud Container Registry. By default, the Kubernetes master (API server) stores secrets as base64 encoded plain text in etcd. In order to enable customer-managed encryption control for the secrets, IBM Kubernetes Service now provides support for Keep Your Own Key (KYOK) through integration with Hyper Protect Crypto Services.
  • Persistent datastores used by the app: IBM Cloud Kubernetes Service allows customers to store data on persistent storage. Supported storage types include VPC Block Storage and Cloud Object Storage, both of which integrate with Hyper Protect Crypto Services to provide customers with KYOK capability.

The KYOK integration is also available for Red Hat OpenShift on IBM Cloud for protection of Kubernetes secrets.

Enhance your data security posture with a no-code approach to application-level encryption

4 min read - Data is the lifeblood of every organization. As your organization’s data footprint expands across the clouds and between your own business lines to drive value, it is essential to secure data at all stages of the cloud adoption and throughout the data lifecycle. While there are different mechanisms available to encrypt data throughout its lifecycle (in transit, at rest and in use), application-level encryption (ALE) provides an additional layer of protection by encrypting data at its source. ALE can enhance…

The history of the central processing unit (CPU)

10 min read - The central processing unit (CPU) is the computer’s brain. It handles the assignment and processing of tasks, in addition to functions that make a computer run. There’s no way to overstate the importance of the CPU to computing. Virtually all computer systems contain, at the least, some type of basic CPU. Regardless of whether they’re used in personal computers (PCs), laptops, tablets, smartphones or even in supercomputers whose output is so strong it must be measured in floating-point operations per…
