A standard masking rule is a data masking rule that applies a built-in masking technique. A standard masking rule has one input column and one output column.
When you create a standard masking rule, you select the masking technique from a list. You can define one masking technique in a standard masking rule and you can apply the rule to one column.
Test Data Manager has masking techniques that you can select to create masking rules. You can use standard masking techniques based on the source datatype and masking type that you configure for a column. You can restrict the characters in a string to replace and the characters to apply in the mask. When you mask numbers and dates, you can provide a range of numbers for the masked data. You can configure a range that is a fixed or percentage variance from the original number.
