Step 12. Assign Data Masking Rules or Policies to the Source Data

To implement data masking operations, assign masking rules from data domains or policies to one or more columns in the project source that you want to mask.

You can assign a rule to a column through a data domain default rule or by choosing a rule. If the column belongs to a data domain, the default rule appears in the column assignment.

In the project, click

Define | Data Masking

The

Data Masking

view appears.

Select a column to assign a masking rule to.

If the

Domain

field is blank for the column, click the

Policy

column and choose a policy that contains the data masking rule that you want to assign.

Click inside the

Rule

column to view the list of available rules.

The data domain preferred rules appear at the top of the list. The other rules in the policy appear at the bottom of the list.

Select a masking rule.

If you choose a substitution masking rule, you can specify the rule assignment parameters. If you choose a mapplet or advanced rule, you can assign the rule columns to the columns in the project.

Click

Save

for each column that you update.
