Why It Matters

The core goal is to implement proactive controls that prevent Personally Identifiable Information (PII) from being exposed in your Databricks environment before it becomes a privacy violation. Preventing PII exposure in Databricks is critical for organizations subject to GDPR, as it helps you maintain data subject rights and avoid substantial penalties—mitigating the risk of unauthorized access to personal data.

Primary Risk: Data exposure and unauthorized access to PII

Relevant Regulation: GDPR General Data Protection Regulation

A comprehensive prevention strategy delivers automated policy enforcement, continuous monitoring, and ensures ongoing compliance with privacy regulations.

Prerequisites

Permissions & Roles

  • Databricks admin or service principal
  • Unity Catalog admin privileges
  • Ability to configure governance policies

External Tools

  • Databricks CLI
  • Cyera DSPM account
  • Policy enforcement framework

Prior Setup

  • Databricks workspace provisioned
  • Unity Catalog enabled
  • Data classification policies defined
  • Access control framework established

Introducing Cyera

Cyera is a modern Data Security Posture Management (DSPM) platform that discovers, classifies, and continuously monitors your sensitive data across cloud services. By leveraging advanced AI and Named Entity Recognition (NER) models, Cyera automatically identifies PII patterns in Databricks datasets and enforces preventive controls to block unauthorized access before exposures occur, ensuring GDPR compliance in real time.

Step-by-Step Guide

1
Configure Unity Catalog governance

Enable Unity Catalog and set up data classification tags for PII. Create attribute-based access control (ABAC) policies that automatically restrict access to classified PII data.

2
Deploy automated PII prevention

In the Cyera portal, navigate to Protection → Prevention Policies → Add new. Configure real-time scanning with AI-powered PII detection and set up automatic blocking of high-risk exposures.

3
Implement access controls and masking

Configure dynamic data masking for PII fields, establish role-based permissions, and set up automated workflows that prevent unauthorized data sharing or exports.

4
Monitor and enforce compliance

Enable continuous monitoring dashboards, configure GDPR-specific alerts for data subject access requests, and establish automated compliance reporting workflows.
