DevSkim

DevSkim is security linter that highlights common security issues in source code.

The DevSkim GitHub Action outputs a sarif file compatible with GitHub's Security Issues view.

Usage

Add DevSkim to your GitHub Actions pipeline like below.

    - uses: actions/checkout@v4
    - uses: microsoft/DevSkim-Action@v1
    - uses: github/codeql-action/upload-sarif@v2
      with:
        sarif_file: devskim-results.sarif

You can also specify a number of options to the action.

    - uses: microsoft/devskim-action@v1
      with:
        directory-to-scan: path/to/scan
        should-scan-archives: false
        output-filename: devskim-results.sarif
        output-directory: path/to/output (appended to $GITHUB_WORKSPACE)
        ignore-globs: "**/.git/**,*.txt"
        exclude-rules: DS176209,DS148264
        options-json: path/to/options.json
        extra-options: --args --to --devskimAnalyze
