DLP, or Data Loss Prevention, is a crucial tool in any organization’s cybersecurity strategy, helping to protect sensitive data from being lost, misused, or accessed by unauthorized individuals. With breaches occurring at alarming rates and the consequences of these attacks consistently rising, it’s more important than ever to put a robust DLP strategy in place. In the context of the SC-400 Microsoft Information Protection Administrator exam, Microsoft 365’s DLP solution stands as an ideal recommendation.
Microsoft 365’s DLP Solution
Microsoft 365’s DLP solution is a comprehensive tool that aids organizations in identifying, monitoring, and automatically protecting sensitive information across Office 365. It is equipped with deep content analysis capabilities that let it understand and classify data based on its sensitivity.
Key features include:
- Configurable sensitive information types, useful for identifying and classifying data.
- Policy Tips, which educate end users about potential policy violations before they occur.
- Integrated incident reporting and management, providing visibility into occurrences of sensitive data sharing and helping organizations respond effectively.
With this Microsoft offering, organizations can set up DLP rules and policies, stipulating where sensitive data can be stored, how it is shared, and who gets to access it.
Example of Microsoft 365’s DLP Setup
For example, an organization dealing with credit card information could set up a DLP policy using the built-in sensitive information type for Credit Card Number. If someone attempts to share a document containing credit card information outside of the organization, the DLP solution can block the sharing action, notify the user and the admin, and create an incident report for tracking and future reference.
The following steps depict how to create a DLP policy in Microsoft 365:
- In the Security & Compliance Center, select Data loss prevention > Policy > + Create a policy.
- Select the information to protect. Here, you can choose from predefined templates like Financial, Medical and Health, and Privacy. For this example, choose Financial > Credit Card Number.
- Name the policy and set the locations where the policy will apply, such as OneDrive accounts, SharePoint sites, and Exchange email accounts.
- Configure the rules for the policy. This includes setting the conditions that will trigger the rule, the actions that will be taken, and any user notifications or policy tips.
- Review and confirm the settings, then turn on the policy.
