Data Anonymization in SAP HANA

In today's data-driven enterprise landscape, organizations face mounting pressure to protect sensitive information while maintaining data utility for analytics. Data anonymization in SAP HANA has become critical for businesses balancing data privacy obligations with operational requirements.

SAP HANA, a powerful in-memory database platform, processes vast amounts of sensitive business data. According to IBM's 2024 Cost of a Data Breach Report, the average data breach cost reached $4.88 million in 2024, with unauthorized database access being a primary attack vector. Organizations using SAP HANA must implement robust data anonymization strategies to protect PII, financial records, and proprietary data.

This article explores SAP HANA's native data masking capabilities and demonstrates how DataSunrise's Zero-Touch Data Masking enhances protection while streamlining compliance with GDPR, HIPAA, and PCI DSS.

Native SAP HANA Data Anonymization Capabilities

SAP HANA provides several built-in features for implementing data anonymization and data protection. These native capabilities offer foundational tools for masking sensitive information. For comprehensive details, refer to the SAP HANA Security Guide.

1. Data Masking Views

SAP HANA allows administrators to create masking views that hide sensitive data using SQL views with conditional logic:

-- Create a masking view for customer data
CREATE VIEW MASKED_CUSTOMERS AS
SELECT
    CUSTOMER_ID,
    CASE 
        WHEN CURRENT_USER = 'ADMIN' 
        THEN CUSTOMER_NAME
        ELSE 'XXXXX'
    END AS CUSTOMER_NAME,
    CASE 
        WHEN CURRENT_USER = 'ADMIN' 
        THEN CREDIT_CARD_NUMBER
        ELSE CONCAT('****-****-****-', RIGHT(CREDIT_CARD_NUMBER, 4))
    END AS CREDIT_CARD_NUMBER
FROM CUSTOMERS;

2. Anonymization Functions

Built-in functions for common protection scenarios:

-- Using HASH function for one-way anonymization
SELECT 
    CUSTOMER_ID,
    HASH_SHA256(TO_BINARY(EMAIL_ADDRESS)) AS HASHED_EMAIL
FROM CUSTOMER_DATA;

3. Row-Level Security

Restrict data access based on user attributes using role-based access controls:

-- Create analytic privilege
CREATE STRUCTURED PRIVILEGE "CUSTOMER_DATA_ACCESS" 
FOR SELECT ON CUSTOMER_TABLE
FILTER (REGION = SESSION_CONTEXT('USER_REGION'));
