Navigating the EU Data Act for IoT Solutions: Part 2- Data Discovery and Classification, Management, Accessibility, and Governance

This article provides technical guidance for implementing EU Data Act compliance for IoT solutions, focusing on data discovery, classification, management, accessibility, and governance using AWS services.

• Use Amazon Macie to automatically discover and classify PII/PHI data in S3 buckets
• Implement EventBridge and Lambda to tag classified data for access control policies
• Apply IAM attribute-based access control (ABAC) to restrict access based on data classification tags
• Use S3 Object Lambda for just-in-time data redaction without duplicating files
• Anonymize metadata via S3 copy operations, Lambda functions, or S3 Batch Operations
• Enable bulk data access through Amazon Connect, S3 Access Grants, and AWS Transfer Family
• Support SFTP access with temporary credentials via Lambda and Amazon Cognito authentication
• Conduct data audits, review AWS architecture, implement classification, and develop secure data sharing

AWS provides multiple service options for PII detection (Comprehend, Glue, Macie) with different pricing models and data type support to meet compliance requirements.
