Introduction

The U.S. Department of Justice (DOJ) recently introduced a rule restricting access to bulk sensitive personal data, including precise geolocation data, by “countries of concern.” This regulation impacts companies collecting or sharing location data near 738 government-related sites, from military bases to major highways. Non-compliance could lead to enforcement actions, making it critical for businesses to audit their data practices.

Learning Objectives

  • Understand the scope of the DOJ Rule and its impact on geolocation data handling.
  • Identify technical steps to ensure compliance with restricted data access.
  • Implement cybersecurity measures to safeguard sensitive location data.

1. Mapping Restricted Geolocation Data

Command/Tool: Google Maps API + GeoJSON Validation

 Use curl to fetch and validate GeoJSON data (e.g., DOJ's 738 locations) 
curl -o doj_locations.json https://lnkd.in/gC8K2dNp 
jq '.features[] | .properties' doj_locations.json  Validate structure

Step-by-Step:

  1. Download the shared Google Maps data (link above) or use the DOJ’s official coordinates.
  2. Validate the GeoJSON file using `jq` to ensure no corrupt entries.
  3. Cross-reference with internal location datasets to identify overlaps.

2. Auditing Data Access for “Covered Persons”

Command: AWS IAM Policy Check

 List all IAM users/groups with access to S3 buckets storing location data 
aws iam list-users --query 'Users[].UserName' 
aws iam list-groups-for-user --user-name <USER>

Step-by-Step:

  1. Identify storage systems (e.g., S3, SQL databases) holding geolocation data.
  2. Audit permissions using AWS CLI or Azure’s Get-AzRoleAssignment.
  3. Revoke access for foreign entities or contractors flagged as “covered persons.”

3. Blocking Data Brokerage Transactions

Tool: API Gateway Logging (AWS)

 Enable CloudWatch logs for API Gateway 
aws apigateway update-stage --rest-api-id <API_ID> --stage-name prod \ 
--patch-operations op='replace',path='/accessLogSettings/destinationArn',value='<CLOUDWATCH_ARN>'

Step-by-Step:

  1. Log all outbound data transfers to ad networks/AI training partners.
  2. Use regex filters to detect location data (e.g., \d{2}\.\d{4},\s-\d{2}\.\d{4}).

3. Automate alerts for unauthorized sharing attempts.

4. Network Hardening for Mobile Devices

Command: MDM Configuration (Microsoft Intune)

 PowerShell: Enforce location data encryption 
Set-MdmPolicy -PolicyName "LocationDataEncryption" -EncryptionRequired $true

Step-by-Step:

  1. Configure MDM solutions to encrypt location data at rest/transit.
  2. Disable background location services for employees in restricted zones.

3. Implement VPNs for secure data transmission.

5. Mitigating Vulnerabilities in Location APIs

Tool: OWASP ZAP for API Security Testing

 Scan location API endpoints for leaks 
docker run -t owasp/zap2docker-stable zap-api-scan.py -t https://api.example.com/location -f openapi

Step-by-Step:

  1. Test APIs for insecure endpoints exposing raw coordinates.
  2. Enforce rate-limiting and API keys for geolocation queries.

3. Patch vulnerabilities like improper `HTTP Referer` headers.

What Undercode Say

Key Takeaways:

  1. Enforcement Priority: The DOJ Rule targets location data near government sites, making non-compliance a high-risk liability.
  2. Technical Debt: Legacy systems sharing location data via APIs or third parties require immediate retrofitting.
  3. Global Impact: Multinationals must reconcile this rule with GDPR/CCPA, as overlapping restrictions complicate compliance.

Analysis:

The DOJ’s focus on geolocation data reflects growing concerns about nation-state tracking. Companies must adopt zero-trust architectures, automating checks for “covered persons” and geo-fenced data flows. Future rules may expand to biometric or IoT data, necessitating proactive cybersecurity investments.

Prediction

By 2026, geolocation compliance tools will integrate AI-driven anomaly detection, flagging high-risk data transfers in real time. Meanwhile, enforcement actions will likely target ad-tech firms and mobility apps first, setting precedents for broader industry adaptation.
