DO425: Red Hat Security: Securing Containers and OpenShift

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

Red Hat Security: Securing Containers and OpenShift (DO425) is designed to help infrastructure administrators and security professionals learn 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.

Course Overview
You will learn about 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.
