The "Security" tab in a GitHub repository serves as a centralized dashboard for viewing and managing security alerts. It provides a security overview that aggregates findings from various GitHub Advanced Security (GHAS) features. This overview explicitly displays the number of open alerts for Code scanning, Dependabot, and Secret scanning, allowing repository maintainers to quickly assess the security posture and prioritize actions. The tab is designed for alert triage and management, not for configuration of security settings.

B. Two-factor authentication (2FA) options are managed at the user account or organization level, not within a specific repository's Security tab.

C. Access management, which controls user and team permissions for a repository, is configured in the repository's "Settings" tab, under "Collaborators and teams."

D. GHAS settings, such as enabling or disabling Code scanning or Secret scanning, are configured in the repository's "Settings" tab under "Code security and analysis."

"About the Security tab." This document states

"The Security tab is the central place to view and manage security alerts and features for your repository... The security overview shows which security features are enabled for the repository and provides a summary of the alerts for each feature." This directly supports that the number of alerts is displayed.

"Managing security and analysis settings for your repository." This page details the configuration of GHAS features. It specifies that these settings are located under the repository's "Settings" tab

then "Code security and analysis

" confirming that option D is incorrect.

"Managing access to your organization's repositories." This documentation clarifies that repository access levels and collaborator management (Option C) are handled within the repository's main "Settings" tab

not the "Security" tab.

"Securing your account with two-factor authentication (2FA)." This resource confirms that 2FA (Option B) is a personal account security setting

configured through the user's profile settings

and is not related to an individual repository's Security tab.
