What is the Report on Compliance (ROC)?
This individual, certified by the PCI SSC, is trained to conduct formal assessments of an organization's PCI DSS compliance.

What is the Luhn algorithm?
This requirement mandates multifactor authentication for all remote network access and a maximum 15-minute inactivity timeout.

Merchants not required to undergo an on-site assessment may instead complete this self-assessment validation tool.
What is the Self-Assessment Questionnaire (SAQ)?
This type of professional investigates payment card security incidents to determine how a breach occurred and its extent.
What is a PCI Forensic Investigator (PFI)?
This term describes treating PCI controls as part of an ongoing, risk-based strategy rather than a point-in-time determination.
What is 'business as usual'?
Unlike cardholder data, this category — including full magnetic stripe data, CVV2, and PIN blocks — may never be stored after authorization, even encrypted.
What is sensitive authentication data?
This requirement calls for strong cryptography in transit and forbids sending unprotected PANs by email, chat, or text.
What is 'encrypt transmission of cardholder data across open, public networks'?

What is 'maintain a policy that addresses cybersecurity for all personnel'?
This organization, approved by the PCI SSC, is required to perform quarterly external vulnerability scans for entities with externally facing IPs.
What is an Approved Scanning Vendor (ASV)?
Fines for a card data compromise, imposed on the issuing bank and passed down to the merchant, may reach up to this amount per incident.
What is $500,000?
