How OpenShift enables container security

Copia URL

Red Hat® OpenShift® delivers a modern, scalable approach to securing the entire application platform stack, from operating system to container to application.

Red Hat closes acquisition of StackRox.

  • Control the trusted sources of content, testing, and deployments.
  • Defend applications from attacks and vulnerabilities in all layers of the platform.
  • Enable and extend secure services through standard interfaces and APIs.

Managing security is a continuous process. As applications are deployed or updated, it’s critical to provide dynamic security controls to keep the business safe. Red Hat OpenShift can apply security controls to the software supply chain, improving the security of applications without reducing developer productivity. Red Hat allows businesses to control, defend, and extend their application platform throughout the application lifecycle.

Container host and platform multitenancy

Red Hat® Enterprise Linux® manages multitenancy of the container runtime: Using Linux namespaces, SELinux, CGroups, and Secure Computing Mode (seccomp) to isolate and protect containers.

Security and trusted content sources

With over 70% of public application content having a security vulnerability, it’s critical to work with trusted sources. Red Hat Ecosystem Catalog delivers validated application content from Red Hat Application Services and certified ISV partners.

The new Compliance Operator provides a declarative way to specify and achieve security compliance for the Red Hat OpenShift cluster.

Securing the container registry

Registries play a critical role in the secure software supply-chain, frequently interacting across the application lifecycle. Red Hat OpenShift provides an integrated container registry that allows applications to be scanned for vulnerability and cryptographically signed for trusted identification. When using Red Hat OpenShift with Red Hat Quay with Clair for vulnerability scanning, vulnerability data is visible in the Red Hat OpenShift console.

Securing the build pipeline

The Continuous Integration/Continuous Delivery (CI/CD) pipeline is at the core of a more secure software supply chain. Red Hat OpenShift integrates tightly with Jenkins and other standard CI/CD tools to manage builds, code inspection, and validation. Red Hat OpenShift S2I allows for secure application builds directly on the platform.

Managing secure container deployments

By default, Red Hat OpenShift prevents containers from running as root. In addition, Red Hat OpenShift enables granular deployment policies that allow operations, security, and compliance teams to enforce quotas, isolation, and access protections.

Managing the secure container application platform

From authentication to authorization to secrets management, Red Hat OpenShift integrates secure operational capabilities to ensure trust between users, applications, and security policies.

Secure container application platform on any cloud

Red Hat OpenShift can be securely deployed across any cloud platform, including bare metal, virtualization, VMware, OpenStack, AWS, Azure, and GCP.

Defend the network

Red Hat OpenShift provides security features for multi-tenant networking and fine-grained network control. All traffic to the control plane is encrypted. Application traffic is encrypted with Red Hat OpenShift Service Mesh.

Secure the data

Red Hat OpenShift provides strong encryption controls to protect sensitive data including platform secrets and application configuration data. Red Hat OpenShift optionally uses FIPS 140-2 Level 1 compliant encryption modules to meet security standards for U.S. federal departments.

Managing secure API endpoints and gateways

Red Hat OpenShift integrates Red Hat 3scale API Management to authenticate, secure, and rate-limit API access to applications and services.
