Summary

This pull request introduces a new GitHub Actions workflow to integrate the DevSkim static analysis tool into the CI/CD pipeline. The workflow is designed to scan code for security issues and upload the results to the GitHub Security tab.

New Workflow Integration:

• .github/workflows/devskim.yml: Added a new workflow named "DevSkim" that runs on push and pull_request events for the main branch, as well as on a weekly schedule. It uses the microsoft/DevSkim-Action to perform security scans and uploads the results in SARIF format using the github/codeql-action/upload-sarif action.

Issue Reference

Fixes: AB#37674

Once the scans have completed and the checks have passed, the analysis results for this pull request branch will appear on this overview. Once you merge this pull request, the 'Security' tab will show more code scanning analysis results (for example, for the default branch). Depending on your configuration and choice of analysis tool, future pull requests will be annotated with code scanning analysis results. For more information about GitHub code scanning, check out the documentation.

• [nitpick] The job ID 'lint' is generic and may not clearly reflect that it's running DevSkim scans; consider renaming it to 'devskim' or similar for clarity.

• Ensure the 'devskim-results.sarif' file exists at the expected path; consider configuring the DevSkim action with an explicit output path or adding a verification step before uploading.
