What the DLP functions look for

Data loss prevention (DLP) policies can use sensitive information types to identify sensitive items. Credit card number and EU debit card number are examples of sensitive information types. Sensitive information types look for specific patterns. Sensitive information types validate the data by looking at it's format, it's checksums, and looks for relevant keywords or other information. Some of this functionality is performed by internal functions. For example, the Credit Card Number sensitive information type uses a function to look for dates that are formatted like an expiration date. This helps to corroborate that a number is a credit card number.

This article explains what these functions look for, to help you understand how the predefined sensitive information types work. For more information, see Sensitive information type entity definitions
