To exclude specific files or directories from being scanned by secret scanning in GitHub Actions, you can use the paths-ignore: key within your YAML workflow file.

This tells GitHub to ignore specified paths when scanning for secrets, which can be useful for excluding test data or non-sensitive mock content.

Other options listed are invalid:

branches-ignore: excludes branches, not files.

decrypt_secret.sh is not a YAML key.

secret scanning.yml is not a recognized filename for configuration.

Comprehensive and Detailed Explanation:

When GitHub identifies a vulnerable dependency in a repository with Dependabot alerts enabled, it performs the following actions:​

Generates a Dependabot alert: The alert is displayed on the repository's Security tab, providing details about the vulnerability and affected dependency.​

Notifies repository maintainers: By default, GitHub notifies users with write, maintain, or admin permissions about new Dependabot alerts.​

These actions ensure that responsible parties are informed promptly to address the vulnerability.​

GitHub code scanning integrates with third-party static analysis tools through SARIF, the Static Analysis Results Interchange Format. A compatible analysis tool generates its findings as a SARIF file, which GitHub can process and display as code scanning alerts within the repository. GitHub supports SARIF output generated outside GitHub, including results from external CI/CD systems or security-analysis products. The results can then be uploaded to GitHub using an appropriate workflow action, API, or supported integration. YAML is commonly used for GitHub Actions workflow configuration but is not the interchange format for code scanning findings. ESLint is an analysis tool rather than a results-exchange specification, and ECMAScript defines JavaScript language standards. Therefore, SARIF is the required output format.

For compiled languages, CodeQL performs extraction by monitoring the normal build process . This means it watches your usual build commands (like make, javac, or dotnet build) and extracts the relevant data from the actual build steps being executed. CodeQL uses this information to construct a semantic database of the application.

This approach ensures that CodeQL captures a precise, real-world representation of the code and its behavior as it is compiled, including platform-specific configurations or conditional logic used during build.

The first step when you receive a secret scanning alert is to revoke the secret if it is still valid. This ensures the secret can no longer be used maliciously. Only after revoking it should you proceed to remove it from the code history and apply other mitigation steps.

Simply deleting the secret from the code does not remove the risk if it hasn’t been revoked — especially since it may already be exposed in commit history.

Secret validation checks whether a secret found in your repository is still valid and active with the issuing provider (e.g., AWS, GitHub, Stripe). If a secret is confirmed to be active, the alert is marked as verified , which means it's considered a high-priority issue because it presents an immediate security risk.

This helps teams respond faster to valid, exploitable secrets rather than wasting time on expired or fake tokens.

Dependency review and secret scanning are capabilities associated with GitHub Advanced Security. In GitHub's current product structure, dependency review is included with GitHub Code Security, while secret scanning is a central capability of GitHub Secret Protection. Both products are components of the broader GitHub Advanced Security offering, and legacy GHAS licenses can include the combined capabilities. The dependency graph is an important supply-chain feature and provides the underlying dependency inventory, but it is broadly available beyond the licensed GHAS feature set and is enabled by default for public repositories. A repository security policy, normally provided through SECURITY.md, is also a general repository capability rather than one of the licensed Advanced Security features being tested. Therefore, dependency review and secret scanning are the correct selections.
