Signing code integrity policies prevents policies from being tampered with after they're deployed. You can sign code integrity policies with the Device Guard signing portal.
Sign your code integrity policy
Before you get started, be sure to review these best practices:
- Test your code integrity policies on a group of devices before deploying them to a large group of devices.
- Use rule options 9 and 10 during testing. For more information, see the section Code integrity policy rules in the Device Guard deployment guide.
To sign a code integrity policy
- Sign in to the Microsoft Store for Business or Microsoft Store for Education.
- Click Manage, click Store settings, and then click Device Guard.
- Click Upload to upload your code integrity policy.
- After the files are uploaded, click Sign to sign the code integrity policy.
Click Download to download the signed code integrity policy.
When you sign a code integrity policy with the Device Guard signing portal, the signing certificate is added to the policy. This means you can't modify this policy. If you need to make changes, make them to an unsigned version of the policy, and then resign the policy.
