Learn to mitigate and manage threats to OpenShift container-based infrastructure

Red Hat Security: Securing Containers and OpenShift with exam (DO426) helps infrastructure administrators and security professionals learn and validate how to identity and mitigate threats to OpenShift container-based infrastructure. The curriculum also covers how to implement and manage secure architecture, policies, and procedures for modern containerized applications and software-defined networking.

This course is based on Red Hat® Enterprise Linux® 7.5, Red Hat® OpenShift® Container Platform 3.11, and Red Hat® Identity Manager 7.5. The offering also includes Red Hat Certified Specialist in Security: Containers and OpenShift Container Platform exam (EX425).

Course overview

You will learn and validate your skills in using secure and trusted container images, registries, and source code; managing network and storage isolation; implementing application single sign-on; and configuring appropriate security constraints and service role–based access control. You will also find out how existing core Linux technologies—such as namespaces, cgroups, seccomp, capabilities, and SELinux—provide a robust and mature host environment with strongly secure containers.

Course content summary

  • Learn Linux multitenancy isolation and least-privilege technologies.
  • Investigate trusted repositories, as well as signing and scanning images.
  • Implement security in a continuous integration and continuous development (CI/CD) pipeline.
  • Integrate web application single sign-on.
  • Automate policy-based deployments.
  • Configure security context constraints (SCC).
  • Manage API access control.
  • Provide secure network I/O.
  • Deliver secure storage I/O.

Impact of this training

Impact on the organization

Containers and container orchestration platforms, such as OpenShift and Kubernetes, have become pervasive in enterprise computing. Container environments have introduced new attack vectors, exploits, and vulnerabilities. Enterprises require strong security, and the migration to containerized microservices has upended traditional network-based security models. Developers must prove that their code, images, and deployments are trusted and secure.

This offering is intended to develop and validate the skills needed to maintain a high level of security in the evolving world of containerized applications and OpenShift installations. OpenShift is an enterprise-grade, container-based application platform that provides the mature security of Red Hat Enterprise Linux and additional mechanisms of security assurance for service role access control, build process hardening, source image layered trust, and controlled deployment management. These security features may help your organization efficiently reduce risk of security breaches, which have a high cost in business disruption, brand erosion, loss of customer and shareholder trust, and financial costs for post-incident remediation. In addition, your organization may be able to use the tools in this offering to help demonstrate that compliance requirements set by customers, auditors, or other stakeholders have been met.

Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.

Impact on the individual

As a result of taking this course and exam, you should be able to use security technologies included in Red Hat OpenShift Container Platform and Red Hat Enterprise Linux to manage security risk and help meet compliance requirements. You should be able to demonstrate these skills:

  • Use recommend practices to ensure that images for container deployment come from trusted sources, including the use of secure registries, signed images, secure access protocols, and authorized access controls.
  • Explain and implement advanced SELinux techniques to restrict access by users, processes, and virtual machines.
  • Configure security context constraints to control the actions that pods can perform and to declare what a pod has the ability to access.
  • Implement the Linux computer security (seccomp) and Linux capabilities features to control the vulnerability footprint of a containerized application.
  • Implement and configure single sign-on for web applications, including the use of JWT for token sharing.
  • Explain and implement network isolation and encryption techniques to segregate application traffic to allow only authorized access.
  • Implement and explain storage management techniques to segregate volume storage I/O to allow only authorized access.
  • Observe and explain how the build process can be extended to include automated security testing and vulnerability scanning to ensure that no exploits are introduced into the final container images to be deployed.
  • Manage container deployment policies and configuration to control application placement, resource capacity, container affinity, and application demand scaling.
  • Manage OpenShift project access and quotas to ensure private and authorized self-service access, as well as to limit exposure to rogue tokens and denial-of-service attempts.
