What is trivy ?

Trivy stands out as the leading open-source security scanner, offering reliability, speed, and user-friendliness. Its capabilities include identifying vulnerabilities, Infrastructure as Code (IaC) misconfiguration, Cloud scanning, Kubernetes security risks, and more.

Provide Clear Guidance: Deliver step-by-step instructions for seamlessly integrating Trivy vulnerability scanning into Azure DevOps pipelines, ensuring accessibility for users at every step.

Enhance Security Practices: Educate users on the significance of vulnerability scanning in the software development lifecycle, illustrating how Trivy can pinpoint and mitigate potential security risks effectively.

Facilitate Adoption: Advocate for adopting best practices by elucidating the benefits of incorporating Trivy into Azure DevOps pipelines. This integration can bolster the overall security posture and mitigate the risk of vulnerabilities in deployed applications.

Implementation Details

We’re integrating Trivy vulnerability scanning into Azure DevOps pipelines for repository and Kubernetes cluster scanning. Trivy proves to be a comprehensive security scanner for containers and container images, capable of detecting vulnerabilities within Docker containers and Kubernetes clusters.

Repository Scanning with Trivy

Install Trivy Extension: Utilize the Trivy Official extension available in the Azure DevOps Marketplace.

Add Trivy Task to Pipeline: Insert the provided Trivy task into your Azure DevOps pipeline YAML configuration. This task executes a Trivy scan within the repository, targeting specified files.

Result

The report should look like this,

Kubernetes Cluster Scanning with Trivy

Configure Kubernetes Connection: Establish a connection to your Kubernetes cluster using the Kubernetes service connection in Azure DevOps, ensuring necessary permissions are granted.

Get Vulnerability Reports from Cluster: Utilize the kubectl get vulnerabilityreports command to retrieve vulnerability reports from the Kubernetes cluster and save the results to a file.

Convert Reports to HTML: Employ scripting to convert the vulnerability reports to HTML format for better visualization.

Result

The report should look like this,

Conclusion

In conclusion, integrating Trivy vulnerability scanning into Azure DevOps pipelines represents a significant step forward in fortifying software development and deployment processes. By following the clear guidance provided and leveraging Trivy’s capabilities, users can enhance their security practices, mitigate potential risks, and foster consistency across their environments.
