Apply a sensitivity label to content automatically

When you create a sensitivity label, you can automatically assign that label to content containing sensitive information, or you can prompt users to apply the label that you recommend.

The ability to apply sensitivity labels to content automatically is important because:

  • You don't need to train your users on all of your classifications.

  • You don't need to rely on users to classify all content correctly.

  • Users no longer need to know about your policies - they can instead focus on their work.

Note

The capability to apply labels automatically requires an Azure Information Protection P2 subscription. To use this feature, you must Download and install the Azure Information Protection unified labeling client. We're working on native support for this feature in Office apps, so that it won't require the Azure Information Protection unified labeling client. Also, the unified labeling client runs only on Windows, so this feature is not yet supported on Mac, iOS, and Android.

Auto labeling options for sensitivity labels

Apply a sensitivity label automatically based on conditions

One of the most powerful features of sensitivity labels is the ability to apply them automatically to content that matches certain conditions. In this case, people in your organization don't need to apply the sensitivity labels - Office 365 does the work for them.

You can choose to apply sensitivity labels to content automatically when that content contains specific types of sensitive information. When you configure a sensitivity label to be applied automatically, you see the same list of sensitive information types as when you create a data loss prevention (DLP) policy. So you can, for example, automatically apply a Highly Confidential label to any content that contains customers' personally identifiable information (PII), such as credit card numbers or social security numbers.

Options for instance count and match accuracy

After you choose your sensitive informaton types, you can refine your condition by changing the instance count or match accuracy. For more information, see Tuning rules to make them easier or harder to match.

Further, you can choose whether a condition must detect all of the sensitive infromation types, or just one of them. And to make your conditions more flexible or complex, you can add groups and use logical operators between the groups. For more information, see Grouping and logical operators.

When a sensitivity label is automatically applied, the user sees a notification in their Office app. They can choose OK to dismiss the notification.

Notification that a document had a label applied automatically

Recommend that the user apply a sensitivity label

If you prefer, instead of applying a sensitivity label automatically to content, you can recommend to your users that they apply the label. This option provides your users the flexibility of accepting the classification and any associated protection, or dismissing the recommendation if the label is not suitable for their document or email.

Note that recommended labels are supported in Word, PowerPoint, and Excel (and require that the Azure Information Protection unified labeling client is installed). We're working on support for recommended labels in Outlook.

Option for reccommending a sensitivity label to users

Here's an example of a prompt when you configure a condition to apply a label as a recommended action, with a custom policy tip. You can choose what text is displayed in the policy tip.

Prompt to apply a recommended label

  • Automatic labeling applies to Word, Excel, and PowerPoint when documents are saved, and to Outlook when emails are sent. These conditions detect sensitive information in the body text in documents and emails, and to headers and footers -- but not in the subject line or attachments of email.

  • You cannot use automatic classification for documents and emails that were previously manually labeled, or previously automatically labeled with a higher classification. Remember, a document or email can have only a single sensitivity label applied to it (in addition to a single retention label).

  • Recommended classification applies to Word, Excel, and PowerPoint when documents are saved. We're working on support for recommended labeling in Outlook.

  • You cannot use recommended classification for documents that were previously labeled with a higher classification. In this case, when the content's already labeled with a higher classification, the user won't see the prompt with the recommendation and policy tip.

How multiple conditions are evaluated when they apply to more than one label

The labels are ordered for evaluation according to their position that you specify in the policy: The label positioned first has the lowest position (least sensitive) and the label positioned last has the highest position (most sensitive). For more information on priority, see Label priority (order matters).

Remember, a parent label (a label with sublabels) can't be applied to content. Make sure that you don't configure a parent label to be auto-applied or recommended, because the parent label won't be applied to content in Office apps that use the Azure Information Protection unified labeling client. For more information on parent labels and sublabels, see Sublabels (grouping labels).
