Leveraging Microsoft Office 365 to Comply with NIST 800-171

Office 365 NIST 800-171

Depending on the customers you serve and the industry in which you operate, there may be mandates to which you must comply in regard to the security of data.

For example:

  • The NIST 800-53 mandate describes security controls that must be in place for any US federal information system. Companies doing business directly with the government, such as DoD contractors, must follow this mandate.

NIST compliance

  • The HIPAA law requires that patient health information be encrypted, and that healthcare organizations take steps to prevent security breaches.
  • Other industries have regulations for personally identifiable information (PII), social security numbers, credit card information, and other sensitive data.

By using the Data Loss Prevention (DLP) feature of Office 365, you can identify, monitor, and automatically protect sensitive information across Office 365.

Office 365 Data Loss Prevention (DLP) Feature

As shown on this pricing sheet listing features of the various Microsoft Office 365 packages, Enterprise versions of the platform include an "Information Protection" feature (including Rights Management and Data Loss Prevention for emails). By leveraging this feature, you can make significant progress down the path to meeting your compliance goals.

The DLP feature of Office 365 enables you to:

  • Identify stored documents that contain credit card numbers
  • Prevent your users from accidentally sharing confidential information with those outside the company
  • Help users stay compliant without interrupting their workflow

The Advantages of DLP

Unlike a simple text scan, the DLP feature leverages deep content analysis to perform keyword matches, dictionary matches, the evaluation of regular expressions, internal functions, and other methods to detect content that matches your DLP policies.

The solution is less intrusive than others because by protecting only the information considered sensitive, fewer people are affected.

The DLP feature protects content in:

  • Exchange Online
  • OneDrive for Business sites
  • SharePoint Online sites
  • Office 2016 desktop programs (Excel 2016, PowerPoint 2016, and Word 2016)
