DefinitionPCI DSS is the card industry's security standard for protecting credit cardholder data, set by a body established by the international card brands.
ExplanationIt applies to merchants, payment service providers, and others that store, process, or transmit card information, with requirements such as network defense, protection of stored data, access restriction, and regular monitoring and testing. It is an industry standard rather than a law, but businesses are bound to comply through their contracts with card companies.
AnalogyIt is like vault rules agreed among banks. Every bank guards its vault with the same rules for door locks, entry logs, and regular inspections.
