Dependabot alert and advisory details can include a CVE identifier, a GHSA identifier, and associated CWE classifications. CVE provides the standardized identifier for a publicly known vulnerability. GitHub assigns a unique GHSA ID to advisories in the GitHub Advisory Database, while CWE identifies the underlying category or class of software weakness associated with the vulnerability. GitHub's Dependabot alert interface exposes these values when they are available. EPSS is also now surfaced by GitHub and can be used to prioritize alerts, but EPSS is a probability-based exploit-risk score, not one of the three vulnerability identifiers/classifications being tested by this question. SAST describes a security-analysis methodology rather than an advisory classification. Therefore, the intended selections are CVE, GHSA, and CWE: C, D, and E.

Comprehensive and Detailed Explanation:

When configuring Dependabot via the dependabot.yml file, the following fields are mandatory for each update configuration:

directory: Specifies the location of the package manifest within the repository. This tells Dependabot where to look for dependency files.​

package-ecosystem: Indicates the type of package manager (e.g., npm, pip, maven) used in the specified directory.​

schedule.interval: Defines how frequently Dependabot checks for updates (e.g., daily, weekly). This ensures regular scanning for outdated or vulnerable dependencies.​

The milestone field is optional and used for associating pull requests with milestones. The allow field is also optional and used to specify which dependencies to update.​

GitLab

In a repository's Security tab, you can view:

Secret scanning alerts : Exposed credentials or tokens

Dependabot alerts : Vulnerable dependencies from the advisory database

Code scanning alerts : Vulnerabilities in code detected via static analysis (e.g., CodeQL)

You won’t see general "security status alerts" (not a formal category) or permission-related alerts here.

Dependabot alerts can identify vulnerable direct dependencies declared in a manifest and vulnerable indirect or transitive dependencies when GitHub can determine their versions from a lockfile. GitHub's dependency graph extracts dependency information from supported manifest and lock files and compares identified package versions against security advisories in the GitHub Advisory Database. Direct dependencies explicitly declared in manifests therefore qualify for vulnerability detection. Transitive dependencies recorded with resolvable versions in lockfiles can also generate alerts. A “loose” dependency declaration may not provide GitHub with a sufficiently specific installed version to establish that the project actually uses a vulnerable release, while a particular time such as 08:00 UTC has nothing to do with whether a dependency qualifies for an alert. Thus, A and C are correct.

GitHub secret scanning examines the repository comprehensively rather than limiting analysis to selected files or dependency metadata. GitHub states that secret scanning scans the entire Git history across all branches for supported secrets. Consequently, both current files and historical versions of files can be inspected, which is why simply deleting a leaked credential in a later commit does not eliminate the security risk. The feature searches repository content for supported provider, generic, and other enabled secret patterns. Dependencies themselves are handled primarily through dependency graph and Dependabot functionality and are not a secret-scanning scope category. Therefore, the correct selections are all branches, the full commit history, and all files in the repository.

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.​

GitHub Advanced Security features can be managed at both the organization and repository levels. Organization owners can control security configurations and Advanced Security access across repositories from the organization's Settings area. At the repository level, administrators can manage eligible security and analysis features through the repository's Settings, subject to any policies or security configurations enforced by the organization or enterprise. Current GitHub terminology separates Advanced Security into products such as GitHub Secret Protection and GitHub Code Security, but the same management hierarchy applies. The organization's Repository permissions area manages general repository access permissions rather than feature licensing or enablement, while enterprise settings primarily establish higher-level policies rather than directly serving as the normal per-repository control described here.

For GitHub Enterprise Server, secret scanning and code scanning are Advanced Security capabilities that require instance-level availability and configuration before organizations and repositories can use them. GitHub's GHES administration documentation identifies code scanning and secret scanning as security products that site administrators enable and configure for the appliance. Dependency review operates through repository dependency data and GitHub Actions rather than being one of the corresponding appliance-level Management Console options described by this question. Dependabot version updates are also a separate Dependabot capability for automatically keeping dependencies current and are not the requested GHAS Management Console security option. GitHub's newer licensing terminology may refer to these capabilities through GitHub Secret Protection and GitHub Code Security, but the functional distinction tested by the question remains the same.

Comprehensive and Detailed Explanation:

To receive Dependabot alert notifications for a repository, you can utilize the following Watch settings:

Custom setting: Allows you to tailor your notifications, enabling you to subscribe specifically to security alerts, including those from Dependabot.​

All Activity setting: Subscribes you to all notifications for the repository, encompassing issues, pull requests, and security alerts like those from Dependabot.​

The Participating and @mentions setting limits notifications to conversations you're directly involved in or mentioned, which may not include security alerts. The Ignore setting unsubscribes you from all notifications, including critical security alerts.​
