How to Implement Data Masking in SAP BW/4HANA

Data masking is a technique that protects sensitive or confidential data from unauthorized access by transforming the data in such a way that it is only visible partially or rendered completely meaningless, while still appearing real and consistent. Data masking can be applied to data at rest (stored in databases) or data in motion (transferred between systems).

In this blog post, we will show you how to implement data masking in SAP BW/4HANA, the data warehouse solution that is highly optimized for the SAP HANA platform. We will also provide some examples of data masking scenarios using the available tools and features of SAP BW/4HANA and SAP HANA.

What is SAP BW/4HANA?

SAP BW/4HANA is a data warehouse solution that offers a managed approach to data warehousing. This means that prefabricated templates (building blocks) are offered for building a data warehouse in a standardized way. SAP BW/4HANA leverages the power and speed of SAP HANA to provide real-time insights and analytics on large volumes of data from various sources.

SAP BW/4HANA consists of four key areas: data modeling, data acquisition, analysis and agile access to information via BW Workspaces. Data modeling is the process of defining the structure, relationships and semantics of the data in the data warehouse. Data acquisition is the process of extracting, transforming and loading (ETL) data from various sources into the data warehouse. Analysis is the process of querying, reporting and visualizing the data in the data warehouse. Agile access to information is the process of creating ad-hoc views and queries on the data in the data warehouse without affecting the underlying data model.

Why is Data Masking Important in SAP BW/4HANA?

Data masking is important in SAP BW/4HANA for several reasons:

  • Data masking helps to ensure data privacy by protecting sensitive or confidential data from unauthorized access or exposure. This helps to comply with regulatory requirements, such as GDPR, HIPAA, PCI DSS, and others.
  • Data masking helps to ensure data security by preventing data breaches or leaks that may compromise the integrity, availability or confidentiality of the data. This helps to avoid reputational damage, legal liability or financial losses.
  • Data masking helps to enable data analysis by providing realistic and consistent data for testing, development or training purposes. This helps to improve the quality, performance and reliability of the data warehouse applications.

How to Implement Data Masking in SAP BW/4HANA?

SAP BW/4HANA does not provide a native feature for data masking, but it can leverage the capabilities of SAP HANA and other SAP products to implement data masking in different levels and perspectives. Some of these capabilities are:

  • SAP HANA Data Masking: SAP HANA provides a feature for data masking that can be applied to tables and views. A column mask protects sensitive or confidential data in a particular column of a table or view by transforming the data in such a way that it is only visible partially or rendered completely meaningless for an unprivileged user, while still appearing real and consistent. A user who has the UNMASKED object privilege for the table or view can see the original data. SAP HANA Data Masking can be used for rowstore and columnstore tables, as well as SQL and calculation views. It supports string data types, such as VARCHAR, NVARCHAR, SHORTEXT and ALPHANUM.
  • UI Data Protection Masking for SAP S/4HANA: UI Data Protection Masking for SAP S/4HANA is a solution that allows you to protect sensitive or confidential data values at field level by masking, clearing, hiding or disabling fields for those users who are not authorized to view or edit this data. It consists of several functions, such as data protection masking, data blocking, application blocking, attribute-based authorization, reveal on demand and recording tool. UI Data Protection Masking for SAP S/4HANA can be configured for various UI channels, such as SAP GUI, WebClient UI, Web Dynpro ABAP, SAPUI5 and SAP Fiori applications.
  • SAP Data Anonymization: SAP Data Anonymization is a solution that allows you to anonymize sensitive or confidential data by applying various techniques, such as generalization, suppression, perturbation or pseudonymization. It consists of several components, such as anonymization engine, anonymization cockpit, anonymization library and anonymization adapter. SAP Data Anonymization can be used for various scenarios, such as test system creation,data extraction, data analysis and data sharing.
