One of the most common data classifications. The sensitive data in the PCI category includes cardholder data such as the cardholder’s name, their primary account number, and the card’s expiration date and security code. It also includes sensitive authentication data such as magnetic-stripe data and the equivalent data contained on a chip, or PINs. In order to prevent credit card fraud, the PCI Security Standards Council (SSC) created the Payment Card Industry Data Security Standard (PCI DSS) in 2004. PCI DSS is a security standard used by payment card companies around the world to securely process, store, and transfer cardholder data. All credit cards have PCI DSS security measures in place to protect cardholders from card fraud and identity theft.
