External Sharing Visibility for NIST 800-53 Compliance

Learn how EXT-06 helps you meet NIST 800-53 requirements for Microsoft 365 and Entra ID security.

NIST 800-53 compliance requires implementing specific controls around external sharing visibility. This page explains how TrueConfig's EXT-06 control helps you meet NIST 800-53 requirements in your Microsoft 365 environment.

How EXT-06 Addresses NIST 800-53 Requirements

NIST 800-53 requires organizations to implement controls around external sharing visibility. The EXT-06 control provides:

  • External sharing links in SharePoint/OneDrive are tracked
  • Anonymous "Anyone with the link" shares are identified
  • External sharing activity is reviewed regularly

These measures directly support NIST 800-53 compliance by ensuring proper external security in your Microsoft 365 environment.

Implementation for Compliance

To satisfy NIST 800-53 requirements with this control:

  • **Enable the control** - Follow the manual configuration steps
  • **Document your implementation** - Record how the control was configured
  • **Maintain evidence** - TrueConfig automatically logs compliance status
  • **Monitor continuously** - Track any deviations from the expected state

Evidence Collection

For NIST 800-53 audits, you'll need to demonstrate:

  • Current configuration state
  • Historical compliance data
  • Remediation actions taken
  • Continuous monitoring in place

TrueConfig provides all of this evidence through its audit trail and reporting features.

Why This Control Matters for NIST 800-53

External sharing is the most common data leakage vector. Without visibility into what is shared externally, you cannot assess your data exposure risk or detect sensitive data being shared inappropriately.

Implementing EXT-06 is an important step toward NIST 800-53 compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to NIST 800-53 requirements.
