The Sensitive Data Masking feature allows message fields to be designated as holding sensitive data by adding the attribute sensitive="1" to the element describing the field. Fields so designated are masked in the diagnostic and HTTP logs and in memory. For example, a request or response containing the following dictionary structure:
<type name="CardHolderData"> <element name="name" type="string" offset="0" size="32"/> <element name="cardNumber" type="string" size="32" sensitive="1"/> </type>
Would appear in the diagnostic log as shown in the following fragments:
{ "CardHolderData": { "name" : "John Doe", "cardNumber" : "****************" } }
