Why It Matters

The core goal is to identify every location where employee information is stored within your Databricks environment, so you can remediate unintended exposures before they become breaches. Scanning for employee data in Databricks is a priority for organizations subject to GDPR, as it helps you prove you've discovered and accounted for all sensitive HR assets—mitigating the risk of data exposure to unauthorized parties.

Primary Risk: Data exposure of employee personal information

Relevant Regulation: GDPR General Data Protection Regulation

A thorough scan delivers immediate visibility, laying the foundation for automated policy enforcement and ongoing compliance with employee data protection requirements.

Prerequisites

Permissions & Roles

  • Databricks admin or service principal
  • catalogs/read, schemas/read, tables/read privileges
  • Ability to install Databricks CLI or Terraform

External Tools

  • Databricks CLI
  • Cyera DSPM account
  • API credentials

Prior Setup

  • Databricks workspace provisioned
  • Unity Catalog enabled
  • CLI authenticated
  • Networking rules configured

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-powered Named Entity Recognition (NER) models, Cyera automatically identifies employee data patterns such as employee IDs, social security numbers, performance reviews, and compensation details within your Databricks environment. This ensures you stay ahead of accidental exposures and meet GDPR audit requirements in real time.

Step-by-Step Guide

1
Configure your Databricks workspace

Ensure Unity Catalog is enabled in your account and create a service principal with the minimum required privileges for employee data discovery.

2
Enable scanning workflows

In the Cyera portal, navigate to Integrations → DSPM → Add new. Select Databricks, provide your host URL and service principal details, then define the scan scope focusing on HR and employee-related schemas.

3
Integrate with third-party tools

Configure webhooks or streaming exports to push scan results into your SIEM or Security Hub. Link findings to existing ticketing systems like Jira or ServiceNow for employee data breach notifications.

4
Validate results and tune policies

Review the initial detection report, prioritize tables with large volumes of employee PII, and adjust detection rules to reduce false positives. Schedule recurring scans to maintain visibility over employee data locations.

Best Practices & Tips

Performance Considerations

  • Start with HR and people analytics schemas
  • Use sampling for very large employee datasets
  • Tune sample rates for speed vs coverage

Tuning Detection Rules

  • Maintain allowlists for synthetic test employee data
  • Adjust confidence thresholds for employee identifiers
  • Match rules to your GDPR risk tolerance

Common Pitfalls

  • Missing employee data in analytics workspaces
  • Over-scanning temporary HR test datasets
  • Neglecting historical employee records in archived tables
