Protecting pushes with secret scanning

You can use secret scanning to prevent supported secrets from being pushed into your organization or repository by enabling push protection.

Secret scanning is available for organization-owned repositories in GitHub Enterprise Server if your enterprise has a license for GitHub Advanced Security. For more information, see "GitHub's products."

Note: Your site administrator must enable secret scanning for GitHub Enterprise Serverインスタンス before you can use this feature. For more information, see "Configuring secret scanning for your appliance."

Note: Secret scanning as a protection push is currently in beta and subject to change. To request access to the beta release, contact your account management team.

About push protection for secrets

Up to now, >- Secret scanning checks for secrets after a push and alerts users to exposed secrets. When you enable push protection, secret scanning also checks pushes for high-confidence secrets (those identified with a low false positive rate). Secret scanning lists any secrets it detects so the author can review the secrets and remove them or, if needed, allow those secrets to be pushed.

If a contributor bypasses a push protection block for a secret, GitHub:

  • generates an alert.
  • creates an alert in the "Security" tab of the repository.
  • adds the bypass event to the audit log.

Secret scanning as a push protection currently scans repositories for secrets issued by the following service providers.

If access to a resource requires paired credentials, then secret scanning will create an alert only when both parts of the pair are detected in the same file. This ensures that the most critical leaks are not hidden behind information about partial leaks.

Enabling secret scanning as a push protection

For you to use secret scanning as a push protection, the organization or repository needs to have both GitHub Advanced Security and secret scanning enabled. For more information, see "Managing security and analysis settings for your organization," "Managing security and analysis settings for your repository," and "About GitHub Advanced Security."

Organization owners, security managers, and repository administrators can enable push protection for secret scanning via the UI and API. For more information, see "Repositories" and expand the "Properties of the security_and_analysis object" section in the REST API documentation.

Enabling secret scanning as a push protection for an organization

  1. GitHub Enterprise Serverインスタンスで、Organizationのメインページにアクセスしてください。
  2. Organization 名の下で、クリックします Settings. Organizationの設定ボタン
  1. In the "Security" section of the sidebar, click Code security and analysis.

  2. Under "Code security and analysis", find "GitHub Advanced Security."

  3. "Secret scanning"の下の"Push protection(プッシュ保護)"の下で、Enable all(すべて有効化)をクリックしてください。 任意のOrganizationでsecret scanningのプッシュ保護を有効化する方法を示しているスクリーンショット

  4. あるいは、"Automatically enable for private repositories added to secret scanning"をクリックしてください。

Enabling secret scanning as a push protection for a repository

Using secret scanning as a push protection from the command line

When you attempt to push a supported secret to a repository or organization with secret scanning as a push protection enabled, GitHub will block the push. You can remove the secret from your commit or follow a provided URL to allow the push.

Up to five detected secrets will be displayed at a time on the command line. If a particular secret has already been detected in the repository and an alert already exists, GitHub will not block that secret.

If you need to remove the secret from your latest commit (that is, HEAD) on the branch being pushed and any earlier commits that contain the secret, you can remove the secret from HEAD, then squash the commits between when the commit was introduced and the first version of HEAD for which the secret has been removed.

Notes:

  • If your git configuration supports pushes to multiple branches, and not only to the default branch, your push may be blocked due to additional and unintended refs being pushed. For more information, see the push.default options in the Git Docs.
  • If secret scanning upon a push times out, GitHub will still run a scan after the push.

Allowing a blocked secret to be pushed

If GitHub blocks a secret that you believe is safe to push, you can allow the secret and specify the reason why it should be allowed.

If you confirm a secret is real and that you intend to fix it later, you should aim to remediate the secret as soon as possible. For example, you might revoke the secret and remove the secret from the repository's commit history. For more information, see "Removing sensitive data from a repository."

When you allow a secret to be pushed, an alert is created in the "Security" tab. GitHub closes the alert and doesn't send a notification if you specify that the secret is a false positive or used only in tests. If you specify that the secret is real and that you will fix it later, GitHub keeps the security alert open and sends notifications to the author of the commit, as well as to repository administrators. For more information, see "Managing alerts from secret scanning."

  1. Visit the URL returned by GitHub when your push was blocked. Screenshot showing form with options for unblocking the push of a secret
  2. Choose the option that best describes why you should be able to push the secret.
    • If the secret is only used in tests and poses no threat, click It's used in tests.
    • If the detected string is not a secret, click It's a false positive.
    • If the secret is real but you intend to fix it later, click I'll fix it later.
  3. Click Allow me to push this secret.
  4. Reattempt the push on the command line within three hours. If you have not pushed within three hours, you will need to repeat this process.
