In NDLP PPS (Personal Public Service) policy, we are trying to reduce the false positive incidents however when we add a new keyword its generating incidents for all.
Release : 15.8
Component : Default-Sym
Create a Data Identifiers (DI)
Defined an example pattern '\d{7}[a-wA-W]' without the quotes
Add the validation checks as 'Exclude Prefix'
Exclude prefix data as 'IE,VAT,TAX, vat,VaT 'etc
Test the behavior using 'dlptest.com' website on the endpoint environment
Please note that the detection is performed but it not recognized by the Endpoint and it will generate a new incident.
A Test Scenario was recreated inhouse and the Data Identifiers behavior we found based on the defined DI, the Endpoint would not differentiate the prefix (VAT or vat or VaT etc) and it will consider the defined keywords as same.
To answer this in simple terms - It's case insensitive.
