About security overview
Security overview provides high-level summaries of the security status of an organization or enterprise and makes it easy to identify repositories that require intervention. You can also use security overview to see which repositories have enabled specific security features and to configure any available security features that are not currently in use.
Security overview shows which security features are enabled for repositories, and includes repository and alert-focused views so you can quickly investigate security issues and take action to remediate them.
- Risk and coverage information about Dependabot features and alerts is shown for all repositories.
- Risk and coverage information for GitHub Advanced Security features, such as code scanning and secret scanning, is shown for enterprises that use GitHub Advanced Security.
For more information, see "Dependabot アラートについて and "GitHub Advanced Security について."
The views are interactive with filters that allow you to look at the aggregated data in detail and identify sources of high risk or low feature coverage. As you apply multiple filters to focus on narrower areas of interest, all data and metrics across the view change to reflect your current selection. For more information, see "Filtering alerts in security overview."
Note: Security overview displays active alerts raised by security features. If there are no alerts shown in security overview for a repository, undetected security vulnerabilities or code errors may still exist or the feature may not be enabled for that repository.
About security overview for organizations
The application security team at your company can use the different views for both broad and specific analyses of your organization's security status. For example, they can use the overview page to monitor adoption of features by your organization or by a specific team as you roll out GitHub Advanced Security to your enterprise, or to review all alerts of a specific type and severity level across all repositories in your organization.
You can find security overview on the Security tab for any organization that's owned by an enterprise. Each view shows a summary of the data that you have access to. As you add filters, all data and metrics across the view change to reflect the repositories or alerts that you've selected. For information about permissions, see "Permission to view data in security overview."
Understanding the main security overview
Each repository is shown in security overview with an indicator for each type of security feature and how many alerts there are of each type. If a security feature is not enabled for a repository, the indicator for that feature will be grayed out. In addition, a risk score is calculated for each repository based on its code scanning, Dependabot and secret scanning alerts. This score is in beta and should be used with caution. Its algorithm and approach is subject to change.
|Code scanning alerts. For more information, see "コード スキャンについて."|
|Secret scanning alerts. For more information, see "シークレット スキャンについて."|
|Dependabot alerts. For more information, see "Dependabot アラートについて."|
|The security feature is enabled, but does not raise alerts in this repository.|
|The security feature is not supported in this repository.|
About security overview for teams
You can find security overview on the Security tab for any team in an organization that's owned by an enterprise.
At the team level, security overview displays repository-specific security information for repositories that the team has admin privileges for. For more information, see "Organization のリポジトリに対するチームのアクセスを管理する."
