Understanding Data Classification
Data classification involves tagging data with labels that denote its level of sensitivity. These classifications often range from public or non-sensitive information to highly confidential or sensitive data.
Data Classification Levels
Common data classification levels include:
- Public: Information that can be freely shared with the public.
- General: Data that is not sensitive and has minimal restrictions.
- Confidential: Information that could harm individuals or the organization if disclosed.
- Highly Confidential: Highly sensitive data that could cause severe damage if compromised.
Microsoft’s Data Classification Capabilities
Microsoft provides a suite of tools within its security and compliance solutions that enable robust data classification.
Microsoft Information Protection (MIP)
MIP is a framework that provides data classification across various Microsoft services. It allows organizations to:
- Classify data based on sensitivity.
- Apply labels manually or automatically.
- Protect data through encryption and access controls.
Azure Information Protection (AIP)
AIP, part of MIP, is a cloud-based solution that helps an organization to classify and optionally protect its data by applying labels.
- Manual Labeling: Users can apply labels to documents and emails manually.
- Automatic Labeling: Policies can be set to classify data automatically based on content, context, and other attributes.
Compliance Center
Microsoft 365 Compliance Center offers data classification tools that work across Office 365 applications. It includes:
- Data Loss Prevention (DLP): Identifies sensitive data across Office 365 and prevents accidental sharing.
- Sensitivity Labels: Allows classification and protection of content in Office 365.
Comparison of Tools
| Feature | Microsoft Information Protection | Azure Information Protection | Compliance Center |
|---|---|---|---|
| Data Classification | Yes | Yes | Yes |
| Manual Labeling | Yes | Yes | Yes |
| Automatic Labeling | Yes | Conditional | Yes |
| Encryption | Yes | Yes | Conditional |
| Centralized Label Management | Yes | Yes | Yes |
| Integration with Office 365 DLP | Yes | Yes | Yes |
| Policy Tips and User Notifications | Yes | Yes | Yes |
Examples of Data Classification in Action
An organization dealing with customer financial information may classify data as follows:
- Public: Marketing materials available on its website.
- General: Internal newsletters not containing sensitive information.
- Confidential: Customer contact information.
- Highly Confidential: Customer credit card details or social security numbers.
In this case, the organization might use AIP to automatically classify documents containing social security numbers as “Highly Confidential” and apply encryption. Meanwhile, DLP policies will prevent this classified data from being sent to unauthorized recipients.
Conclusion
Effective data classification ensures that sensitive information is well-protected while still being accessible to authorized individuals. Microsoft’s range of data classification capabilities present in its security and compliance solutions are designed to help organizations navigate complex data landscapes, securing sensitive data against threats, and meeting regulatory compliance requirements. Understanding and utilizing these capabilities is essential for IT professionals and is a component expected to be mastered for the SC-900 Microsoft Security, Compliance, and Identity Fundamentals exam.
