Incident and operations management

This documentation details the Red Hat responsibilities for the OpenShift Dedicated managed service.

Platform monitoring

A Red Hat Site Reliability Engineer (SRE) maintains a centralized monitoring and alerting system for all OpenShift Dedicated cluster components, SRE services, and underlying cloud provider accounts. Platform audit logs are securely forwarded to a centralized SIEM (Security Information and Event Monitoring) system, where they might trigger configured alerts to the SRE team and are also subject to manual review. Audit logs are retained in the SIEM for one year. Audit logs for a given cluster are not deleted at the time the cluster is deleted.

Incident management

An incident is an event that results in a degradation or outage of one or more Red Hat services. An incident can be raised by a customer or Customer Experience and Engagement (CEE) member through a support case, directly by the centralized monitoring and alerting system, or directly by a member of the SRE team.

Depending on the impact on the service and customer, the incident is categorized in terms of severity.

The general workflow of how a new incident is managed by Red Hat:

  1. An SRE first responder is alerted to a new incident, and begins an initial investigation.

  2. After the initial investigation, the incident is assigned an incident lead, who coordinates the recovery efforts.

  3. The incident lead manages all communication and coordination around recovery, including any relevant notifications or support case updates.

  4. The incident is recovered.

  5. The incident is documented and a root cause analysis is performed within 3 business days of the incident.

  6. A root cause analysis (RCA) draft document is shared with the customer within 7 business days of the incident.

Notifications

Platform notifications are configured using email. Any customer notification is also sent to the corresponding Red Hat account team and if applicable, the Red Hat Technical Account Manager.

The following activities can trigger notifications:

  • Platform incident

  • Performance degradation

  • Cluster capacity warnings

  • Critical vulnerabilities and resolution

  • Upgrade scheduling

Backup and recovery

All OpenShift Dedicated clusters are backed up using cloud provider snapshots. Notably, this does not include customer data stored on persistent volumes. All snapshots are taken using the appropriate cloud provider snapshot APIs and are uploaded to a secure object storage bucket (S3 in AWS, and GCS in Google Cloud) in the same account as the cluster.

  • Red Hat SRE rehearses recovery processes quarterly.

  • Red Hat does not commit to any Recovery Point Objective (RPO) or Recovery Time Objective (RTO).

  • Customers should take regular backups of their data.

  • Backups performed by SRE are taken as a precautionary measure only. They are stored in the same region as the cluster.

  • Customers can access SRE backup data on request by opening a support case.

  • Red Hat highly encourages customers to deploy multi-AZ clusters with workloads that follow Kubernetes best practices to ensure high availability within a region.

  • In the event an entire cloud region is unavailable, customers must install a new cluster in a different region and restore their apps using their backup data.

Cluster capacity

Evaluating and managing cluster capacity is a responsibility that is shared between Red Hat and the customer. Red Hat SRE is responsible for the capacity of all control plane and infrastructure nodes on the cluster.

Red Hat SRE also evaluates cluster capacity during upgrades and in response to cluster alerts. The impact of a cluster upgrade on capacity is evaluated as part of the upgrade testing process to ensure that capacity is not negatively impacted by new additions to the cluster. During a cluster upgrade, additional worker nodes are added to make sure that total cluster capacity is maintained during the upgrade process.

Capacity evaluations by SRE staff also happen in response to alerts from the cluster, once usage thresholds are exceeded for a certain period of time. Such alerts can also result in a notification to the customer.

Change management

This section describes the policies about how cluster and configuration changes, patches, and releases are managed.

Customer-initiated changes

You can initiate changes using self-service capabilities such as cluster deployment, worker node scaling, or cluster deletion.

Change history is captured in the Cluster History section in the OpenShift Cluster Manager Overview tab, and is available for you to view. The change history includes, but is not limited to, logs from the following changes:

  • Adding or removing identity providers

  • Adding or removing users to or from the dedicated-admins group

  • Scaling the cluster compute nodes

  • Scaling the cluster load balancer

  • Scaling the cluster persistent storage

  • Upgrading the cluster

Red Hat-initiated changes

Red Hat site reliability engineering (SRE) manages the infrastructure, code, and configuration of OpenShift Dedicated using a GitOps workflow and fully automated CI/CD pipelines. This process ensures that Red Hat can safely introduce service improvements on a continuous basis without negatively impacting customers.

Every proposed change undergoes a series of automated verifications immediately upon check-in. Changes are then deployed to a staging environment where they undergo automated integration testing. Finally, changes are deployed to the production environment. Each step is fully automated.

An authorized SRE reviewer must approve advancement to each step. The reviewer cannot be the same individual who proposed the change. All changes and approvals are fully auditable as part of the GitOps workflow.

Some changes are released to production incrementally, using feature flags to control availability of new features to specified clusters or customers.

Patch management

OpenShift Container Platform software and the underlying immutable Red Hat Enterprise Linux CoreOS (RHCOS) operating system image are patched for bugs and vulnerabilities in regular z-stream upgrades. Read more about RHCOS architecture in the OpenShift Container Platform documentation.

Release management

Red Hat does not automatically upgrade your clusters. You can schedule to upgrade the clusters at regular intervals (recurring upgrade) or just once (individual upgrade) using the OpenShift Cluster Manager web console. Red Hat might forcefully upgrade a cluster to a new z-stream version only if the cluster is affected by a critical impact CVE. You can review the history of all cluster upgrade events in the OpenShift Cluster Manager web console. For more information about releases, see the Life Cycle policy.

Identity and access management

Most access by Red Hat site reliability engineering (SRE) teams is done by using cluster Operators through automated configuration management.

Subprocessors

For a list of the available subprocessors, see the Red Hat Subprocessor List on the Red Hat Customer Portal.

SRE access to all OpenShift Dedicated clusters

SREs access OpenShift Dedicated clusters through a proxy. The proxy mints a service account in an OpenShift Dedicated cluster for the SREs when they log in. As no identity provider is configured for OpenShift Dedicated clusters, SREs access the proxy by running a local web console container. SREs do not access the cluster web console directly. SREs must authenticate as individual users to ensure auditability. All authentication attempts are logged to a Security Information and Event Management (SIEM) system.

Privileged access controls in OpenShift Dedicated

Red Hat SRE adheres to the principle of least privilege when accessing OpenShift Dedicated and public cloud provider components. There are four basic categories of manual SRE access:

  • SRE admin access through the Red Hat Customer Portal with normal two-factor authentication and no privileged elevation.

  • SRE admin access through the Red Hat corporate SSO with normal two-factor authentication and no privileged elevation.

  • OpenShift elevation, which is a manual elevation using Red Hat SSO. It is fully audited and management approval is required for every operation SREs make.

  • Cloud provider access or elevation, which is a manual elevation for cloud provider console or CLI access. Access is limited to 60 minutes and is fully audited.

Each of these access types has different levels of access to components:

SRE access to cloud infrastructure accounts

Red Hat personnel do not access cloud infrastructure accounts in the course of routine OpenShift Dedicated operations. For emergency troubleshooting purposes, Red Hat SRE have well-defined and auditable procedures to access cloud infrastructure accounts.

In AWS, SREs generate a short-lived AWS access token for the BYOCAdminAccess user using the AWS Security Token Service (STS). Access to the STS token is audit logged and traceable back to individual users. The BYOCAdminAccess has the AdministratorAccess IAM policy attached.

In Google Cloud, SREs access resources after being authenticated against a Red Hat SAML identity provider (IDP). The IDP authorizes tokens that have time-to-live expirations. The issuance of the token is auditable by corporate Red Hat IT and linked back to an individual user.

Red Hat support access

Members of the Red Hat CEE team typically have read-only access to parts of the cluster. Specifically, CEE has limited access to the core and product namespaces and does not have access to the customer namespaces.

Cloud Infrastructure Account refers to the underlying AWS or Google Cloud account

  1. Limited to addressing common use cases such as failing deployments, upgrading a cluster, and replacing bad worker nodes.

  2. Red Hat associates have no access to customer data by default.

  3. SRE access to the cloud infrastructure account is a "break-glass" procedure for exceptional troubleshooting during a documented incident.

  4. Customer administrator has limited access to the cloud infrastructure account console through Cloud Infrastructure Access.

  5. Limited to what is granted through RBAC by the customer administrator, as well as namespaces created by the user.

Customer access

Customer access is limited to namespaces created by the customer and permissions that are granted using RBAC by the customer administrator role. Access to the underlying infrastructure or product namespaces is generally not permitted without cluster-admin access. More information on customer access and authentication can be found in the Understanding Authentication section of the documentation.

Access approval and review

New SRE user access requires management approval. Separated or transferred SRE accounts are removed as authorized users through an automated process. Additionally, SRE performs periodic access review including management sign-off of authorized user lists.

Security and regulation compliance

Security and regulation compliance includes tasks, such as the implementation of security controls and compliance certification.

Data classification

Red Hat defines and follows a data classification standard to determine the sensitivity of data and highlight inherent risk to the confidentiality and integrity of that data while it is collected, used, transmitted stored, and processed. Customer-owned data is classified at the highest level of sensitivity and handling requirements.

Data management

OpenShift Dedicated uses cloud provider services such as AWS Key Management Service (KMS) and Google Cloud KMS to help securely manage encryption keys for persistent data. These keys are used for encrypting all control plane, infrastructure, and worker node root volumes. Customers can specify their own KMS key for encrypting root volumes at installation time. Persistent volumes (PVs) also use KMS for key management. Customers can specify their own KMS key for encrypting PVs by creating a new StorageClass referencing the KMS key Amazon Resource Name (ARN) or ID.

When a customer deletes their OpenShift Dedicated cluster, all cluster data is permanently deleted, including control plane data volumes and customer application data volumes, such a persistent volumes (PV).

Vulnerability management

Red Hat performs periodic vulnerability scanning of OpenShift Dedicated using industry standard tools. Identified vulnerabilities are tracked to their remediation according to timelines based on severity. Vulnerability scanning and remediation activities are documented for verification by third-party assessors in the course of compliance certification audits.

Network security

Firewall and DDoS protection

Each OpenShift Dedicated cluster is protected by a secure network configuration at the cloud infrastructure level using firewall rules (AWS Security Groups or Google Cloud Compute Engine firewall rules). OpenShift Dedicated customers on AWS are also protected against DDoS attacks with AWS Shield Standard.

Private clusters and network connectivity

Customers can optionally configure their OpenShift Dedicated cluster endpoints (web console, API, and application router) to be made private so that the cluster control plane or applications are not accessible from the Internet.

For AWS, customers can configure a private network connection to their OpenShift Dedicated cluster through AWS VPC peering, AWS VPN, or AWS Direct Connect.

At this time, private clusters are not supported for OpenShift Dedicated clusters on Google Cloud.

Cluster network access controls

Fine-grained network access control rules can be configured by customers per project by using NetworkPolicy objects and the OpenShift SDN.

Penetration testing

Red Hat performs periodic penetration tests against OpenShift Dedicated. Tests are performed by an independent internal team using industry standard tools and best practices.

Any issues that are discovered are prioritized based on severity. Any issues found belonging to open source projects are shared with the community for resolution.

Compliance

OpenShift Dedicated follows common industry best practices for security and controls. The certifications are outlined in the following table.

Disaster recovery

OpenShift Dedicated provides disaster recovery for failures that occur at the pod, worker node, infrastructure node, control plane node, and availability zone levels.

All disaster recovery requires that the customer use best practices for deploying highly available applications, storage, and cluster architecture (for example, single-zone deployment vs. multi-zone deployment) to account for the level of desired availability.

One single-zone cluster will not provide disaster avoidance or recovery in the event of an availability zone or region outage. Multiple single-zone clusters with customer-maintained failover can account for outages at the zone or region levels.

One multi-zone cluster will not provide disaster avoidance or recovery in the event of a full region outage. Multiple multi-zone clusters with customer-maintained failover can account for outages at the region level.
