Data Masking Overview

Data Masking Overview

Enterprise Data Preparation
integrates with Informatica Dynamic Data Masking, a data security product, to enable masking of sensitive data in data assets.
The DDM for Hive Service listens for requests from
Enterprise Data Preparation
. Dynamic Data Masking applies masking rules to columns in the requested table according to the masking policies defined, ensuring that data visible in the
Enterprise Data Preparation
application is appropriately masked for each user.
When
Enterprise Data Preparation
users view or perform operations on columns containing masked data, the actual data is fully or partially obfuscated based on the masking rules applied.
Data masking can be applied to data in the following scenarios:
When previewing data.
When a user previews a data asset that is in the data lake or in an external database, data is masked according to the masking rules defined on the source data.
When importing data from an external database.
When a user imports data from an external database, data masking rules are applied to the data in the Hive table created for the asset.
When preparing data.
During data preparation, columns in worksheets are populated with masked data according to the masking policies defined on the source data. When a user performs a blending operation such as a join or lookup, data in masked columns cannot be blended with unmasked columns.
When exporting or downloading data to an external database or file.
When a user exports data from the data lake to an external database, or downloads data to a file, data is written to the database or file in masked format.
When publishing data.
When a user publishes prepared data, data in columns that were masked during data preview, data sampling, and data preparation is written to the Hive table in masked format.
