Configuring secret scanning for your repositories

Enabling secret scanning

You can enable secret scanning for any repository that is owned by an organization. Once enabled, secret scanningはGitHubリポジトリ中に存在するすべてのブランチのGit履歴全体に対して、あらゆるシークレットをスキャンします。

1. On your GitHub Enterprise Server instance, navigate to the main page of the repository.

2. リポジトリ名の下の [ 設定] をクリックします。

3. In the left sidebar, click Security & analysis.

4. If Advanced Security is not already enabled for the repository, to the right of "GitHub Advanced Security", click Enable.

5. Review the impact of enabling Advanced Security, then click Enable GitHub Advanced Security for this repository.

6. When you enable Advanced Security, secret scanning may automatically be enabled for the repository due to the organization's settings. If "Secret scanning" is shown with an Enable button, you still need to enable secret scanning by clicking Enable. If you see a Disable button, secret scanning is already enabled.

Excluding directories from secret scanning

You can use a secret_scanning.yml file to exclude directories from secret scanning. For example, you can exclude directories that contain tests or randomly generated content.

1. On your GitHub Enterprise Server instance, navigate to the main page of the repository.

2. ファイルの一覧の上にある、 [ファイルの追� ] ドロップダウンを使用し、 [新しいファイルの作成] をクリックします。

3. In the file name field, type .github/secret_scanning.yml.

4. Under Edit new file, type paths-ignore: followed by the paths you want to exclude from secret scanning.

   paths-ignore:
     - "foo/bar/*.js"
   

   You can use special characters, such as * to filter paths. For more information about filter patterns, see "Workflow syntax for GitHub Actions."

   Notes:

   • If there are more than 1,000 entries in paths-ignore, secret scanning will only exclude the first 1,000 directories from scans.
   • If secret_scanning.yml is larger than 1 MB, secret scanning will ignore the entire file.

You can also ignore individual alerts from secret scanning. For more information, see "Managing alerts from secret scanning."
