GitHub-Advanced-Security Exam Dumps - GitHub Advanced Security GHAS Exam

Comprehensive and Detailed Explanation:

To generate a dependency graph for a private repository, GitHub requires:​

Dependency graph enabled: The repository must have the dependency graph feature enabled. This can be configured at the organization level to apply to all new private repositories.​

Access to manifest and lock files: GitHub needs read-only access to the repository's dependency manifest and lock files (e.g., package.json, requirements.txt) to identify and map dependencies.​

TheSecurity tabin a GitHub repository provides a central location for viewing security-related information, especially when GitHub Advanced Security is enabled. The following can be accessed:

Validity checks— where GitHub verifies if a secret is still active — are available forpartner patternsonly. These are secrets issued by GitHub's trusted partners (like AWS, Slack, etc.) and have APIs for GitHub to validate token activity status.

Custom patterns and high entropy patterns donotsupport automated validity checks.

If a secret isintentionally used in a test environmentandposes no real-world security risk, you may close the alert with the reason"used in tests". This helps reduce noise and clarify that the alert was reviewed and accepted as non-critical.

Just being in a test file isn't enough unless itspurpose is purely for testing.

Secrets committed and then deleted are still accessible in therepository’s Git history. To locate them, navigate to theCommitstab. GitHub's secret scanning can detect secrets in both current and historical commits, which is why remediation should also includerevoking the secret, not just removing it from the latest code.

These three features provide a complete layer of defense:

Code scanningidentifies security flaws in your source code

Secret scanningdetects exposed credentials

Dependency reviewshows the impact of package changes during a pull request

Together, they give developers actionable insight into risk and coverage throughout the SDLC.

When defining a custom pattern for secret scanning, two key fields are required:

Name of the pattern: A unique label to identify the pattern

Secret format: A regular expression that defines what the secret looks like (e.g., token format)

You can optionally specifyadditional match requirements(like required context keywords), but they’re not mandatory. Listing repositories is also not part of the required fields during pattern creation.

You can customize CodeQL scanning by including additionalquery packsor by specifying individualqueries:

Packs: These are reusable collections of CodeQL queries bundled into a single package.

Queries: You can point to specific files or directories containing .ql queries to include in the analysis.

github/codeql refers to a pack by name but is not a method or field. Scope is not a valid field used for configuration in this context.
