The <\/span>New<\/span><\/i> Data Class Map File Masking Job<\/span><\/i> wizard in the <\/span>IRI Workbench GUI for FieldShield <\/span><\/a>creates IRI FieldShield<\/a> job (.scl) scripts which, when run, will mask one or more files in one or more LAN directories. The wizard automatically inserts the <\/span>masking functions<\/span><\/a> you previously chose for each class of data (e.g., email addresses, CCNs, names) into the output fields of those job script(s).<\/span><\/p>\n

How Does That Happen?<\/b><\/h5>\n

Behind the scenes, your masking rules get built into FieldShield jobs by the <\/span>New<\/span><\/i> Data Class Map File Masking Job<\/span><\/i> wizard, which picks up the mappings of masking rules to target table(s) columns stored in a\u00a0<\/span>Data Class Map<\/span><\/a> file. That Data Class map is one of the artifacts produced when you run the<\/span> Directory Data Class Search<\/span><\/i><\/a> (PII discovery job) <\/span>wizard<\/span><\/i> to find, report on, and classify the PII in your files and folders.\u00a0<\/span><\/p>\n

Diving Deeper<\/b><\/h5>\n

The Data Class Map, serialized in a .dataClassMap file, contains the m<\/span>appings of your classified columns to the masking rules you defined in your<\/span> Data Class & Rule Library<\/span><\/a> (or .dcrl file, not to be confused with the Data Class Map). Your data classes (like email address, phone number, last name, credit card number, etc.) are also stored in the Data Class & Rule Library.\u00a0<\/span><\/p>\n

The <\/span>Directory Data Class Search<\/span><\/i> wizard performs data classification using Data Class Search Matchers. Search Matchers determine if a column matches a data class by the content of its values (i.e., using <\/span>Data Matchers<\/span><\/a>) or its metadata (i.e., using<\/span> Location Matchers<\/span><\/a>).<\/span><\/p>\n

Running the Masking Job Wizard<\/b><\/b><\/h5>\n

Note that to use the <\/span>New Data Class Map File Masking Job<\/span><\/i> wizard, a Data Class Map is <\/span>required<\/b>. To start the wizard click on the FieldShield icon <\/span> > New Data Class Map File Masking Job.<\/span><\/p>\n

\"\"<\/p>\n

On the Setup page, enter the job details. The option to Generate Flow Diagram that can be toggled on or off.\u00a0<\/span><\/p>\n

If toggled on, a visual workflow diagram with table-specific transform (masking) mapping blocks inside will be generated. Note that generating a Flow Diagram significantly increases the time it takes to generate the job scripts when multiple files are involved.\u00a0\u00a0<\/span><\/p>\n
