If autobuild fails (which attempts to automatically detect how to build your project), you should disable it in your workflow and replace it with explicit build commands , using steps like run: make or run: ./gradlew build.

This ensures CodeQL can still extract and analyze the code correctly.

In a workflow : GitHub Actions workflows are the most common place for CodeQL code scanning. The codeql-analysis.yml defines how the analysis runs and when it triggers.

In an external CI system : GitHub allows you to run CodeQL analysis outside of GitHub Actions. Once complete, the results can be uploaded using the upload-sarif action to make alerts visible in the repository.

You cannot run or trigger analysis from third-party repositories directly, and the Files changed tab in pull requests only shows diff — not analysis results.

Comprehensive and Detailed Explanation:

A CodeQL database contains a representation of your codebase, including the build of the code and extracted data. This database is used to run CodeQL queries to analyze your code for potential vulnerabilities and errors.​

GitHub explicitly notifies the commit author when that person accidentally commits a detected secret, regardless of the author's notification preferences. Repository administrators are also among the users eligible to receive secret-scanning security notifications, subject to their repository watch and email notification configuration. GitHub's current notification model can additionally notify security managers and users with explicitly granted security-alert access, but those choices are not represented accurately by the generic “security analyst” option. Write and Maintain roles alone do not make a user the default repository-wide recipient represented by this question. For incremental scans, users who have security-alert access receive notifications according to their configured notification preferences, while commit authors receive notification regardless. Therefore, among the supplied choices, the expected combination remains the committer and repository administrators: B and C.

Query suite definitions in CodeQL are stored using the .qls file extension. A query suite defines a collection of queries to be run during an analysis and allows for grouping them based on categories like language, security relevance, or custom filters.

In contrast:

.ql files are individual queries.

.qll files are libraries used by .ql queries.

.yml is used for workflows, not query suites.

Secret scanning for a private repository is enabled through the repository's security configuration/settings, currently located under Settings → Security and quality → Advanced Security. In current GitHub terminology, enabling Secret Protection enables secret scanning alerts for an eligible private or internal repository. Repository rulesets control policies such as branch protection, required checks, and merge conditions; they are not the primary mechanism for enabling secret scanning. GitHub also does not use a secret.yml file to activate the feature. Code scanning default setup configures CodeQL analysis and is separate from secret detection. Organization owners can additionally enable Secret Protection and secret-scanning capabilities at scale by applying security configurations to repositories. Consequently, the code security or Advanced Security settings area is the correct location, making A the correct answer.

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.

If a secret is intentionally used in a test environment and poses 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 its purpose is purely for testing .

GitHub allows organization owners and repository administrators to grant additional people or teams access to repository security alerts, including Dependabot alerts, but the recipients must already have write access to that repository. Users with write, maintain, or admin access can normally view relevant repository security alerts, while additional alert-access assignments are also constrained by repository access. A team that merely has Read access to another repository does not satisfy this requirement. Similarly, an outside collaborator with only Read access or an enterprise member who has not been assigned access to the repository cannot be granted the alert access described by the question. Therefore, members of a team that has Write access to the affected repository meet GitHub's permission requirement.

Dependabot builds a dependency graph by analyzing package manifests and lockfiles in your repository. This graph includes both direct and transitive dependencies. It then compares this graph against the GitHub Advisory Database, which includes curated, security-reviewed advisories.

This method provides a comprehensive and automated way to discover all known vulnerabilities across your dependency tree.
