Customize the SQL information protection policy in Azure Security Center (Preview)
A SQL information protection policy can be defined and customized for your entire Azure tenant, in Azure Security Center.
Information protection is an advanced security capability for discovering, classifying, labeling and protecting sensitive data in your Azure data resources. Discovering and classifying your most sensitive data (business, financial, healthcare, PII, etc.) can play a pivotal role in your organizational information protection stature. It can serve as infrastructure for:
- Helping meet data privacy standards and regulatory compliance requirements
- Various security scenarios, such as monitoring (auditing) and alerting on anomalous access to sensitive data
- Controlling access to and hardening the security of data stores containing highly sensitive data
SQL Information Protection implements this paradigm for your SQL data stores, currently supported for Azure SQL Database. SQL Information Protection automatically discovers and classifies potentially sensitive data, provides a labeling mechanism for persistently tagging the sensitive data with classification attributes, and provides a detailed dashboard showing the classification state of the database. In addition, it calculates the result set sensitivity of SQL queries, so that queries that extract sensitive data can be explicitly audited, and the data can be protected. For more details on SQL Information Protection, see Azure SQL Database Data Discovery and Classification.
The classification mechanism is based on two primary constructs that make up the classification taxonomy - Labels and Information Types.
- Labels – The main classification attributes, used to define the sensitivity level of the data stored in the column.
- Information Types – Provides additional granularity into the type of data stored in the column.
Information Protection comes with a built-in set of labels and information types, which are used by default. To customize these, you can customize the information protection policy in Azure Security Center.
Customize the information protection policy
To customize the information protection policy for your Azure tenant, you need to have administrative privileges on the tenant's root management group.
In the Security Center main menu, under RESOURCE SECURITY HYGIENE go to Data & storage and click on the SQL Information Protection button.
In the SQL Information Protection page, you can view your current set of labels. These are the main classification attributes that are used to categorize the sensitivity level of your data. From here, you can configure the Information protection labels and Information types for the tenant.
You can edit or delete any existing label, or add a new label. To edit an existing label, select that label and then click Configure, either at the top or from the context menu on the right. To add a new label, click Create label in the top menu bar or at the bottom of the labels table.
In the Configure sensitivity label screen, you can create or alter the label name and the description. You can also set whether the label is active or disabled by toggling the Enabled switch on or off. Finally, you can add or remove information types associated with the label. Any data discovered that matches that information type will automatically include the associated sensitivity label in the classification recommendations.
Labels are listed in order of ascending sensitivity. To change the ranking between labels, drag the labels to reorder them in the table, or use the Move up and Move down buttons to change the order.
Be sure to click Save at the top of the screen when you are finished.
Adding and customizing information types
You can manage and customize information types by clicking on Manage information types.
To add a new Information type, select Create information type in the top menu. You can configure a name, description, and search pattern strings for the Information type. Search pattern strings can optionally use keywords with wildcard characters (using the character '%'), which the automated discovery engine uses to identify sensitive data in your databases, based on the columns' metadata.
You can also configure the built-in Information types by adding additional search pattern strings, disabling some of the existing strings, or by changing the description. You cannot delete built-in Information types or edit their names.
Information types are listed in order of ascending discovery ranking, meaning that the types higher in the list will attempt to match first. To change the ranking between information types, drag the types to the right spot in the table, or use the Move up and Move down buttons to change the order.
Click OK when you are done.
After you completed managing your information types, be sure to associate the relevant types with the relevant labels, by clicking Configure for a particular label, and adding or deleting information types as appropriate.
Be sure to click Save in the main Labels blade to apply all your changes.
After your Information protection policy is fully defined and saved, it will apply to the classification of data on all Azure SQL databases in your tenant.
