Payment Card Industry Data Security Standard
The Payment Card Industry Data Security Standard (PCI DSS) is a proprietary information security standard for organizations that handle cardholder information for the major debit, credit, prepaid, e-purse, ATM, and POS cards.
Defined by the Payment Card Industry Security Standards Council, the standard was created to increase controls around cardholder data to reduce credit card fraud via its exposure. Validation of compliance is done annually — by an external Qualified Security Assessor (QSA) that creates a Report on Compliance (ROC) for organizations handling large volumes of transactions, or by Self-Assessment Questionnaire (SAQ) and Quarterly Network Scan for companies handling smaller volumes.
Payment Card Industry Data Security Council
Founded in 2006 by the major card brands including American Express, Discover Financial Services, JCB International, MasterCard Worldwide, and Visa Inc, PCI SSC develops, manages, educates, and raises awareness of the three PCI standards and provides documents and information to help organizations implement PCI cardholder data.
