Question

Contoso stores a structured database of 90,000 employee records that includes full names, national ID numbers, and salaries. The compliance team wants a Data Loss Prevention solution that detects when an email or document contains an exact combination of these specific employee values, rather than any generic pattern that merely resembles a national ID. The solution must scale to the full record set and be refreshable as the database changes. Which sensitive information classification method should you implement?

Create an Exact Data Match (EDM) sensitive information type based on a hashed and uploaded schema of the employee records

Answer

Create a custom sensitive information type using a regular expression that matches the national ID number format
