Which Data Requires Data Masking?
Here are the most common data types that require data masking:
Personally identifiable information (PII)—data that can be used to identify certain individuals.
This includes information like full name, passport number, driver’s license number, and social
security number.
Protected health information (PHI)—data collected by healthcare service providers for the
purpose of identifying appropriate care. This includes insurance information, demographic
information, test and laboratory results, medical histories, and health conditions.
Payment card information—the Payment Card Industry Data Security Standard (PCI DSS)
requires merchants that handle credit and debit cards transactions to appropriately secure
cardholder data.
Intellectual property (IP)—data related to creations of the mind, including inventions, business
plans, designs, and specifications, have high value for an organization and must be protected
from unauthorized access and theft.
