You can duplicate a predefined or custom engine if you need to easily copy the functionality of an existing engine for a different use. To duplicate an existing DLP engine:

1. Go to Policies > Data Protection > Common Resources > Dictionaries & Engines > DLP Engines.
2. Click the Clone icon for the DLP engine.
   The Clone DLP Engine window appears.
3. In the Clone DLP Engine window, specify a name for the new engine.
4. For Engine Builder, add operators and DLP dictionaries to build an expression. You can see your expression in the Expression Preview.
   See image.

Under Expression:

1. Select an operator to build your expression. The operators include All (AND), Any (OR), Exclude (AND NOT), and Sum. The Sum operator is available for count-based DLP dictionaries (i.e., Credit Cards, Social Security Numbers, etc.) and allows you to specify the sum total of matches that trigger a group of dictionaries specified in the DLP engine.

For the root expression, only the All (AND), Any (OR), and Sum operators are allowed.

2. Click Add to add a Dictionary or a Subexpression. Click the Remove icon () to delete dictionaries or subexpressions.

• If you use the Sum operator, select two or more predefined or custom DLP dictionaries. You must set a value for the match count. You can enter any value less than 1,000.
• If you use the All, Any, or Exclude operators, you must select a predefined or custom DLP dictionary. Certain dictionaries require you to set a value for the match count. You can enter any value less than 1,000.

• If you click Subexpression, you must select an operator. The operators include All (AND), Any (OR), Exclude (AND NOT), and Sum. The Sum operator is available for count-based DLP dictionaries (i.e., Credit Cards, Social Security Numbers, etc.) and allows you to specify the sum total of matches that trigger a group of dictionaries specified in the subexpression.

You can use the Sum operator as part of a subexpression; however, you cannot add a subexpression to an expression or subexpression that uses the Sum operator.

See image.

3. Continue adding dictionaries and operators to the expression as needed. At each level, you can create up to 4 subexpressions, use up to 4 operators, and add up to 16 dictionaries per operator.
4. (Optional) For Description, enter any additional notes or information. The description cannot exceed 255 characters.
5. Click Save and activate the change.
