Where to Find the Course Reference Page

All the books, articles, white‑papers, and tools referenced throughout the DevSecOps Professional curriculum are compiled in a single, searchable portal:

Reference Hub:
https://portal.practical-devsecops.training/courses/devsecops-professional/introduction-to-the-course/references-used-throughout-the-course/

What You’ll Find on the Reference Hub

• Framework overviews (CIS Benchmarks, NIST, OWASP)
• Tool documentation (Terraform, Docker, Kubernetes, GitHub Actions)
• Security testing utilities (InSpec, Trivy, Gitleaks)
• Video recordings & slide decks from each module
• Downloadable PDFs for offline study

Bookmark this page and use the built‑in filter to quickly locate resources by keyword, format, or module number.

InSpec Control Learning Resources

InSpec is the de‑facto standard for writing infrastructure‑as‑code security tests. Below is a curated list of resources that will help you master InSpec controls—from fundamentals to advanced baseline creation.

1. Official Course Reference Section

All the InSpec‑specific links mentioned in the curriculum are listed on the same Reference Hub (see above). Look for the “InSpec” tag to jump directly to the relevant entries.

2. DevSec.io Baselines

A collection of ready‑made security baselines that demonstrate best‑practice InSpec controls for popular platforms:

• Baseline Library: https://dev-sec.io/baselines/
• GitHub Organization: https://github.com/orgs/dev-sec/repositories?q=baseline&type=all

These baselines cover Linux, Docker, Kubernetes, AWS, Azure, and more. Clone a baseline, run inspec exec <profile> against a test environment, and study the generated reports.

3. Chef InSpec Repository

The official source code, examples, and documentation for InSpec are maintained by Chef:

• GitHub Repo: https://github.com/chef/inspec

Key folders to explore:

• examples/ – small, self‑contained control files you can run instantly.
• docs/ – markdown documentation that mirrors the online help site.
• spec/ – test suites that show how the InSpec engine itself is validated.

4. Additional Learning Aids

GitHub Repositories for InSpec Controls

If you prefer browsing community‑contributed controls, the Dev‑Sec organization aggregates a wealth of repositories:

InSpec‑Focused Repos:
https://github.com/orgs/dev-sec/repositories?q=inspec&type=all

How to Navigate the List

1. Filter by language – Most controls are written in Ruby (*.rb).
2. Sort by stars – Popular repos often contain well‑maintained, production‑ready profiles.
3. Read the README – Authors typically include usage examples, required inputs, and compliance mappings.

Popular repositories to start with

• dev-sec/linux-baseline – Linux security hardening controls.
• dev-sec/docker-baseline – Docker daemon and container security checks.
• dev-sec/kubernetes-baseline – Kubernetes cluster hardening controls.

Clone any repo with git clone <url> and run it locally:

inspec exec path/to/profile -t ssh://user@host

You’ll receive a detailed compliance report that you can export as JSON, HTML, or JUnit XML for CI integration.

Practical Ways to Use These Resources

1. Create a Personal Baseline Library

   • Fork a baseline repo (e.g., dev-sec/linux-baseline).
   • Add organization‑specific controls (e.g., custom port restrictions).
   • Store the fork in your own GitHub account for version control.

2. Integrate InSpec into CI/CD Pipelines

   • Add a step in GitHub Actions or GitLab CI that runs inspec exec against a test environment after each deployment.
   • Use the inspec-json reporter to feed results into security dashboards.

3. Hands‑On Lab Exercise

   • Spin up a vulnerable VM (e.g., Ubuntu 20.04 with default SSH).
   • Execute the dev-sec/linux-baseline profile.
   • Review the failing controls, then remediate the issues and re‑run the scan to see the compliance score improve.

4. Study for the DevSecOps Professional Certification

   • Review each InSpec control in the baseline repos.
   • Write a short summary of what each control checks and why it matters for compliance frameworks (CIS, NIST, PCI‑DSS).
   • Practice explaining the control to a non‑technical stakeholder—this is a common exam scenario.

Common Questions & Quick Tips

Quick Tips for Efficient Learning

• Bookmark the Reference Hub and add a browser tag (e.g., devsecops-ref) for instant access.
• Leverage VS Code extensions like “Ruby” and “InSpec” for syntax highlighting and linting.
• Automate baseline updates with a scheduled GitHub Action that pulls the latest upstream changes from dev-sec/* repos.
• Participate in community discussions on the DevSec.io Slack channel—real‑world scenarios accelerate mastery.

By consolidating the official reference page, curated InSpec learning materials, and community GitHub repositories, you now have a clear roadmap to deepen your DevSecOps expertise and ace the certification. Dive into the resources, experiment with controls in a sandbox, and integrate security testing into your daily workflow—your journey to secure, compliant infrastructure starts here.
