How we do it
Libelle DataMasking (LDM) is a standalone Enterprise Masking Solution to automate the obfuscate of sensitive data. After installing the solution, connections to one or multiple databases or filesystems are established, so called 'Data Stores'. With these connections, Masking Profiles can be built - what fields in which columns should be obfuscated. Profiles can be created from pre-defined templates (e.g. SAP HR), from customer-provided table, column, and field names, or with the help of the LDM explorer which scourts the database structure or SAP Data Dictionary for sensitive data to mask. After Profiles are established, Masking Procedures are assigned to the Profiles. Procedures can be selected from a wide-range of standard templates such as shifting dates within range for date of births, or creating random digits for Social Security Numbers. The configurations are finally saved, and the first masking run is executed. After validation of data structure and performance results, the same process can continue to mask data ad-hoc, or after every system built.
