Within the incident response plan, which party must be notified at a minimum?

• A. Payment brands at a minimum.
• B. Customers only.
• C. Regulators only.
• D. Internal department heads only.

Answer: (A)

When handling cardholder data breaches, the incident response plan must include a defined process for external notification, starting with the payment networks. PCI DSS requires that the plan includes notifying the card brands as a primary external party so they can coordinate the investigation and any required actions. While customers and regulators may need to be informed in many cases, and internal leaders are important for internal coordination, the minimum external notification called for by the standard is to the payment brands. This ensures the breach is escalated to the networks that maintain the card programs and can drive the appropriate response across affected partners.
