Databricks Customer Data Exposure Remediation

Why It Matters

Once customer data exposure has been detected in your Databricks environment, swift remediation is critical to prevent regulatory violations and protect your organization's reputation. Fixing exposed customer data involves implementing proper access controls, data masking, encryption, and ensuring compliance with data protection regulations like GDPR—which requires organizations to protect personal data and can impose fines of up to 4% of annual revenue for violations.

Primary Risk: Data exposure leading to regulatory violations and customer trust erosion

Relevant Regulation: GDPR General Data Protection Regulation

Effective remediation not only addresses immediate exposure risks but also establishes long-term governance to prevent future incidents.

Introducing Cyera

Cyera is a modern Data Security Posture Management (DSPM) platform that not only discovers and classifies sensitive data but also provides AI-powered remediation recommendations. Using advanced machine learning and natural language processing (NLP), Cyera automatically identifies the context and sensitivity of exposed customer data, prioritizes remediation actions based on risk scoring, and provides guided workflows to fix access control issues across your Databricks environment.

Step-by-Step Guide

Assess and prioritize exposed data

Review the exposure findings in Cyera's dashboard to understand the scope, sensitivity level, and access patterns. Prioritize customer data with the highest risk scores and public accessibility.

Implement immediate access restrictions

Use Unity Catalog's RBAC to immediately revoke public access and restrict permissions to authorized users only. Apply attribute-based access control (ABAC) policies for dynamic protection.

REVOKE ALL PRIVILEGES ON TABLE catalog.schema.customer_table FROM account users;

Apply data masking and encryption

Configure column-level security to mask or encrypt sensitive customer fields. Implement dynamic views that show masked data to unauthorized users while preserving full access for legitimate business needs.

CREATE VIEW masked_customers AS SELECT customer_id, MASK(email) as email FROM customers;

Validate remediation and monitor

Run validation scans to confirm exposure has been eliminated. Set up continuous monitoring through Cyera to detect any new exposures and ensure remediation measures remain effective.
