Enabling secret scanning alerts for users

You can enable secret scanning alerts for users for any repository that is owned by an organization. Once enabled, secret scanning scans for any secrets in your entire Git history on all branches present in your GitHub repository. Secret scanning also analyzes issue descriptions and comments for secrets.

1. On GitHub.com, navigate to the main page of the repository.

2. Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings.

   

3. In the "Security" section of the sidebar, click Code security and 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.

   

7. Optionally, if you want to enable push protection, click Enable to the right of "Push protection." 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. For more information, see "Protecting pushes with secret scanning."

Excluding directories from secret scanning alerts for users

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

1. On GitHub.com, navigate to the main page of the repository.

2. Above the list of files, using the Add file drop-down, click Create new file.

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."
