Data Loss Prevention includes over
               100 predefined templates and data identifiers that administrators can use to create
               Data
               Loss Prevention policies. These predefined templates and data identifiers should cover
               the majority of a company’s Data Protection needs. Trend Micro recommends using the
               built-in items when creating policies.
            
If the predefined items do not meet a company’s specific needs,
               administrators can copy the existing items and modify them accordingly.
               Select the desired template or data identifier and click Copy.
               Click the newly created item (<DLP Item>_Copy) to edit the content.

                           Predefined Data Loss Prevention templates and data identifiers
                              cannot be modified or deleted.

            Administrators that require completely new expressions can create
               unique expressions using the web console. ScanMail Data Loss
               Prevention expressions follow the Perl Compatible Regular Expression
               (PCRE) format. Trend Micro recommends testing the user-defined expressions
               before implementing the new expression in a Data Loss Prevention
               policy.
            
            
               
                  
                     |  | Tip
                           Save the expression only if the testing was
                              successful. An expression that cannot detect any data wastes system
                              resources and may impact performance.

            ScanMail allows
               administrators to import and export Data Loss Prevention templates
               and data identifiers in DAT files. To edit the contents of a DAT
               file, import the items back into the ScanMail environment
               first. Modifying the contents of an exported DAT file can cause
               data corruption and unusable data.
