Protect files with Azure Information Protection
Use the steps in this article to configure Azure Information Protection (AIP) to provide encryption and permissions for files in a highly confidential SharePoint Online team site.
The encryption and permissions protection travels with a file even when it is downloaded from the site. For more information about highly confidential SharePoint Online team sites, see Secure SharePoint Online sites and files.
When Azure Information Protection encryption is applied to files stored in Office 365, the service cannot process the contents of these files. Co-authoring, eDiscovery, search, Delve, and other collaborative features do not work. Data Loss Prevention (DLP) policies can only work with the metadata (including Office 365 labels) but not the contents of these files (such as credit card numbers within files).
Configure Azure Information Protection
First, follow the instructions in Activate Azure RMS with the Office 365 admin center for your Office 365 subscription.
Next, configure Azure Information Protection with a new scoped policy and sub-label for protection and permissions for your highly confidential SharePoint Online team site by following these steps:
- Sign in to the Office 365 portal with an account that has the Security Administrator or Company Administrator role. For help, see Where to sign in to Office 365.
- In a separate tab of your browser, go to the Azure portal (https://portal.azure.com).
- If this is the first time you are configuring Azure Information Protection, see these instructions.
- In the list pane, click More services, type information, and click Azure Information Protection.
- On the Azure Information protection blade, click Scoped policies > + Add a new policy.
- Type a name for the new policy in Policy name and a description in Description.
- Click Select which users or groups get this policy > User/Groups, and then select the site members access group for your highly sensitive SharePoint Online team site.
- Click Select > OK.
- For the Highly Confidential label, click the ellipses (…), and then click Add a sub-label.
- Type a name for the sub-label in Name and a description of the label in Description.
- In Set permissions for documents and emails containing this label, click Protect.
- In the Protection section, click Azure (cloud key).
- On the Protection blade, under Protection settings, click + Add permissions.
- On the Add permissions blade, under Specify users and groups, click + Browse directory.
- On the AAD Users and Groups pane, select the site members access group for your highly sensitive SharePoint Online team site, and click Select.
- Under Choose permissions from the preset, clear the Print, Copy and extract content, and Forward check boxes.
- Click OK two times.
- On the Sub-label blade, configure visual markings as needed, and then click Save.
- Close the new scoped policy blade.
- On the Azure Information Protection – Scoped policies blade, click Publish, and then click Yes.
This is the resulting configuration for your highly confidential SharePoint Online team site.
You are now ready to begin creating documents and protecting them with Azure Information Protection and your new label.
You must install the Azure Information Protection client on your device or Windows-based computer. You can script and automate the installation, or users can install the client manually.
For more information, see the following resources:
- The client side of Azure Information Protection
- Installing the Azure Information Protection client
- Download page for manual installation
Once installed, your users run and then sign-in from an Office application (such as Microsoft Word) with their Office 365 account. A new Information Protection bar allows you to select the label.
Make sure that your users know the SharePoint Online team site and which label to use to protect their highly confidential files.
If you have multiple highly sensitive SharePoint Online team sites, you should create multiple Azure Information Protection scoped policies with sub-labels with the above settings, with the permissions for each sub-label set to the site members access group of a specific SharePoint Online team site.
