Protect Your Sensitive Data with Microsoft Purview
Understanding Microsoft Purview Data Loss Prevention (DLP): Safeguard Your Sensitive Data
In today’s digital landscape, protecting sensitive data is more critical than ever. Microsoft Purview Data Loss Prevention (DLP) is a robust tool designed to help organizations prevent the accidental or unauthorized sharing of sensitive information across various Microsoft 365 services, including Outlook, SharePoint, Teams, and OneDrive.
This article covers the essentials of Microsoft Purview DLP, its benefits, and how it helps organizations maintain compliance and data security.
What Is Microsoft Purview Data Loss Prevention?
Microsoft Purview DLP is a feature within the Microsoft Purview compliance suite that helps organizations safeguard sensitive information by detecting and restricting the sharing of data based on pre-set policies. This technology is designed to prevent data leaks by monitoring and controlling data shared within or outside the organization.
With Microsoft Purview DLP, admins can define rules that automatically identify and protect sensitive data such as financial information, personally identifiable information (PII), intellectual property, and more.
Key Features of Microsoft Purview DLP
- Customizable Policies: Administrators can create DLP policies tailored to their organization’s needs, targeting specific data types like credit card numbers, Social Security numbers, and health records.
- Automated Monitoring and Alerts: DLP policies can automatically monitor content across Microsoft 365 applications, identifying and flagging risky sharing activities. Alerts notify admins when sensitive information is at risk, so they can take action promptly.
- Content Inspection: DLP policies inspect files and emails to detect sensitive information, regardless of whether the data is stored in emails, shared on SharePoint, or transmitted through Teams messages.
- Pre-Built Templates for Compliance: Microsoft Purview DLP offers ready-made templates aligned with regulatory requirements, such as GDPR and HIPAA, to make policy creation easy for compliance teams.
- User Education and Notifications: DLP provides end-users with notifications when their actions violate a policy, educating them about secure data handling practices in real time.
How Microsoft Purview DLP Works
Purview DLP works by scanning data within the Microsoft 365 ecosystem according to the rules and policies defined by the organization. For instance, an organization may create a DLP policy that prevents employees from sharing documents containing Social Security numbers with external users. Here’s how the process works:
- Define Policies: Administrators create DLP policies based on specific data types or compliance requirements. For example, a policy could be set to detect and restrict sharing of credit card numbers or other sensitive financial data.
- Apply Conditions and Actions: For each policy, conditions determine what triggers the DLP rule. Actions define what happens when a rule is triggered, such as blocking access, alerting an admin, or notifying the user.
- Monitor and Respond: When a user attempts to share or send sensitive data, Purview DLP checks against the policy. If the action violates the policy, Purview DLP takes action, such as restricting sharing, alerting administrators, or educating the user on why the content is restricted.
Benefits of Microsoft Purview DLP
- Data Security: DLP helps prevent unauthorized sharing of sensitive data, reducing the risk of data breaches.
- Compliance: Built-in templates and customizable policies make it easy for organizations to adhere to compliance regulations such as GDPR, HIPAA, and CCPA.
- Risk Reduction: By identifying risky behavior in real time, DLP minimizes exposure to data loss and protects sensitive information.
- User Awareness: With in-context notifications, employees learn about secure data-sharing practices, fostering a culture of data security within the organization.
