View and Analyze Data Masking Reports

After you run a data masking job, Oracle Data Safe saves all the details about the data masking job in Security Center as an online report and tracks statistics across the top five masking policies for a target database.

Statistics About a Masked Target Database

The following information is available in Data Masking for a masked target database:

• The number of masking policies created for a target database and their names
• Statistics across all policies for a target database: Includes the number of masked sensitive types, schemas, tables, columns, and values
• Charts comparing the percentage of masked values and percentage of masked columns for the top five masking policies.
• Statistics per masking policy: Includes the number of reports available, masked sensitive types, schemas, tables, columns, and values
• Details and statistics for each data masking job: Includes the target database name, masking policy name, report Oracle Cloud Identifier (OCID), the start and finish date/time of the data masking job, and the number of masked sensitive types, schemas, tables, columns, and values. For each column, the schema name, table name, masking format used, sensitive type, parent column, and total number of masked values is provided. Log files are available for the data masking job.
