Sensitive Data Masking
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" : "****************"
}
}
