Technical Support Guide: Lab Errors, Data Privacy, Certificate Validity & Support Channels for Practical DevSecOps Learners

Introduction

Whether you’re troubleshooting an InSpec profile, wondering how your passport data is protected, or need clarity on certificate lifetimes, this guide consolidates the most common support topics for Practical DevSecOps courses. By following the steps and best‑practice tips below, you can resolve lab issues quickly, stay compliant with privacy regulations, and understand the long‑term value of your certifications and support channels.

1. Resolving Lab Execution Issues

1.1 SSH Authentication Errors with the Linux Baseline InSpec Profile

Typical scenario:
You launch the Linux Baseline InSpec profile, but the run fails with an SSH authentication error, even after following the video walkthrough.

Root causes to check:

1. Incorrect SSH credentials – Ensure the username, password, or private key matches the target VM.

2. Network restrictions – Verify that the lab VM allows inbound SSH (port 22) from your IP address.

3. Host key verification – If the VM’s host key changed, the SSH client may reject the connection.

Quick fix:

• Open a terminal and manually ssh into the VM using the same credentials. If you can connect, re‑run the InSpec profile.

• If the manual test fails, regenerate the SSH key pair in the lab environment and update the InSpec ssh_key attribute.

1.2 Switching to Cinc Auditor (formerly Chef InSpec)

If you continue to encounter authentication problems, you may use Cinc Auditor for the Configuration as Code (CaC) job instead of the native InSpec runner.

How to switch:

1. Install Cinc Auditor (if not already installed):

   curl -L https://omnitruck.cinc.sh/install.sh | sudo bash -s -- -P auditor
   

2. Run the same profile with Auditor:

   cinc-auditor exec path/to/linux-baseline-profile
   

3. Provide the same SSH options (--target ssh://user@host) as you would with InSpec.

Cinc Auditor uses the same profile syntax, so no changes to the profile files are required. This alternative often bypasses environment‑specific bugs that affect the InSpec binary.

2. Passport & Verification Document Handling

2.1 What Happens to Your Passport Data?

• No third‑party sharing: Your passport scan or any verification document is never shared outside Practical DevSecOps.

• Immediate deletion: In compliance with SOC 2, ISO 27001, and GDPR, the document is deleted right after verification.

2.2 Retention Period

• Zero‑retention model: Once the identity check is successful, the file is purged from our systems. No backup copies are retained.

3. Certificate Validity & Renewal

3.1 Do DevSecOps Certificates Expire?

Answer: No. All Practical DevSecOps certificates are lifetime credentials. There is no renewal fee or periodic re‑certification requirement.

3.2 When Might You Need an Updated Credential?

• New version releases: If a major course version is launched (e.g., “DevSecOps Engineer v2”), you may choose to earn the updated badge for market relevance.

• Employer requirements: Some organizations request a recent assessment; in that case, you can retake the exam for a fresh certification date.

4. Dedicated Support Channels

4.1 How Long Is a Dedicated Channel Active?

• The channel remains open as long as you interact at least once every 90 days.

• If there is no activity for more than three months, the channel is automatically archived.

4.2 Reactivating an Archived Channel

1. Open a new ticket via the Support Portal.

2. Reference the archived channel ID.

3. Our support team will restore the channel within 24 hours.

5. Getting Help with Lab Issues

5.1 Using the “Chat with support” Feature

All labs include a built‑in Chat with support button. When you click it:

• System logs (including console output) are attached automatically.

Best practice: Add a brief description of what you were trying to accomplish before the error occurred. This context speeds up resolution.

5.2 Example Support Request

“I’m trying to run the Linux Baseline InSpec profile on the Ubuntu VM (IP 192.168.1.10). The run fails with ‘SSH authentication failed – permission denied (publickey)’. I have verified that the private key is uploaded to the lab’s ~/.ssh folder.”

Providing the IP address, error message, and verification steps helps the support team diagnose the issue within minutes.

6. Frequently Asked Questions (FAQs)

7. Tips for Smooth Lab Experiences

• Pre‑flight checklist before running any profile: verify SSH credentials, confirm network connectivity, and ensure the correct version of the tool (InSpec or Cinc Auditor) is installed.

• Bookmark the privacy policy page for quick reference on data handling.

• Set a calendar reminder to interact with your dedicated channel at least once every two months to avoid auto‑archiving.

• Take screenshots of error messages before contacting support; the built‑in chat already captures them, but having a local copy can be handy for follow‑up documentation.

Conclusion

Technical hurdles, data‑privacy concerns, and support logistics can feel overwhelming, but Practical DevSecOps provides clear pathways to resolve each. By leveraging Cinc Auditor as an alternative to InSpec, understanding our strict passport‑data deletion policy, recognizing the lifetime value of your certificates, and using the built‑in chat support effectively, you’ll stay focused on mastering DevSecOps skills rather than troubleshooting roadblocks.

If you encounter any other issues not covered here, don’t hesitate to reach out through the Chat with support button and request a real agent to help you. Happy learning!
