What Is DevSecOps?
DevSecOps is an evolution of DevOps, a methodology that combines software development (Dev) and IT operations (Ops) to streamline application delivery. DevSecOps adds security (Sec) into the mix, embedding it throughout the development lifecycle to ensure applications are secure from the start. The goal is to foster collaboration among development, security, and operations teams, enabling faster releases without compromising safety.
Key principles of DevSecOps:
- Shift-left security: Addressing security early in development, not as an afterthought.
- Automation: Using tools to automate testing, deployment, and security checks.
- Collaboration: Encouraging teamwork across Dev, Sec, and Ops teams.
- Continuous improvement: Regularly refining processes to enhance speed and security.
Containers play a pivotal role in DevSecOps by providing consistent, portable environments that support these principles.
The Role of Containers in DevSecOps
Containers are lightweight, isolated environments that package applications with their dependencies, ensuring they run consistently across development, testing, and production. Tools like Podman, Buildah, and Skopeo, used in the Red Hat Containers Certification, enable efficient container management.
Why containers matter in DevSecOps:
- Consistency: Containers eliminate “it works on my machine” issues, ensuring uniform behavior across environments.
- Speed: They enable rapid deployment and scaling, supporting continuous integration and delivery (CI/CD).
- Security: Containers isolate applications, reducing attack surfaces, and support security scanning.
- Automation: Containers integrate with CI/CD pipelines for automated builds, tests, and deployments.
The Red Hat Containers Certification equips you to leverage these benefits in a DevSecOps workflow.
Overview of the Containers Certification
The Red Hat Certified Specialist in Containers (EX180/EX188) is a performance-based certification that validates your ability to manage containers using Red Hat’s tools: Podman (for running containers), Buildah (for building images), and Skopeo (for managing images). The exam tests practical skills in a live Red Hat Enterprise Linux (RHEL) environment, focusing on tasks like creating containers, configuring storage, and securing workloads.
Key details:
- Duration: 2-3 hours
- Format: Hands-on, performance-based tasks
- Focus: Container management without Kubernetes orchestration
This certification is ideal for professionals in DevSecOps roles, as it aligns with the need for secure, automated, and collaborative workflows.
Key Skills Gained and Their DevSecOps Relevance
The EX180/EX188 certification imparts skills that directly support DevSecOps practices. Here’s a breakdown:
- Container Creation and Management: Using Podman to create and manage containers ensures consistent application deployment, a cornerstone of CI/CD pipelines.
- Container Image Management: Building and managing images with Buildah and Skopeo enables automated builds and secure image distribution.
- Container Storage: Configuring persistent storage supports stateful applications, ensuring data integrity in production.
- Container Networking: Setting up networking enables secure communication in microservices architectures.
- Troubleshooting: Diagnosing issues minimizes downtime, supporting continuous delivery.
- Security Practices: Running containers as non-root users and using SELinux aligns with shift-left security principles.
These skills enable you to contribute to DevSecOps by automating processes, securing applications, and fostering collaboration.
How Containers Certification Integrates with DevSecOps
The EX180/EX188 certification aligns with DevSecOps by equipping you to:
- Automate Workflows: Use Podman and Buildah to automate container builds and deployments in CI/CD pipelines, reducing manual errors.
- Enhance Security: Implement security best practices, like non-root containers and image scanning, to address vulnerabilities early.
- Support Collaboration: Create consistent container environments that developers, security teams, and operators can work with seamlessly.
- Enable Scalability: Manage containers efficiently to support scalable, cloud-native applications.
For example, in a DevSecOps pipeline, you might use Podman to build a containerized web application, scan its image for vulnerabilities with Skopeo, and deploy it securely, ensuring all teams can trust the environment.
Impact on DevSecOps Roles
The skills gained from the certification are directly applicable to key DevSecOps roles:
- DevOps Engineer: Automate container builds and deployments in CI/CD pipelines, ensuring rapid delivery.
- Security Engineer: Secure containers with SELinux and non-root configurations to meet compliance requirements.
- System Administrator: Manage container infrastructure on RHEL, ensuring reliability and performance.
- Cloud Architect: Design container-based solutions for cloud platforms like AWS, Azure, or OpenShift.
These roles benefit from the certification’s focus on practical, hands-on skills that align with DevSecOps goals.
