External Sharing Visibility for Legal Services
How legal services organizations should implement EXT-06 for Microsoft 365 security and compliance.
Legal Services organizations face unique security challenges when managing Microsoft 365 environments. The EXT-06 control (External Sharing Visibility) is particularly important for this sector due to soc2 and iso27001 requirements.
Why Legal Services Organizations Need This Control
Legal Services organizations face specific regulatory requirements including soc2, iso27001, cis. The EXT-06 control helps address these requirements by:
- External sharing links in SharePoint/OneDrive are tracked
- Anonymous "Anyone with the link" shares are identified
- External sharing activity is reviewed regularly
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.
Industry-Specific Considerations
When implementing EXT-06 in a legal services environment, consider:
- **Regulatory requirements**: soc2, iso27001, cis may mandate specific configurations
- **Risk tolerance**: Legal Services organizations typically have moderate to low risk tolerance
- **Audit frequency**: Plan for regular compliance reviews
- **Documentation**: Maintain detailed records for regulatory inspections
Implementation Steps
To implement EXT-06 in your Microsoft 365 environment:
- External sharing links in SharePoint/OneDrive are tracked
- Anonymous "Anyone with the link" shares are identified
- External sharing activity is reviewed regularly
This control requires manual implementation through the Entra admin center.
Legal Compliance Requirements
Legal organizations must comply with these frameworks, all of which address external sharing visibility:
Why This Control Matters for Legal
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.
Common threats in legal services:
- • Business email compromise impersonating partners
- • Wire fraud in real estate transactions
- • Targeted attacks on high-profile cases
