If supermarket chain Hannaford Bros. was compliant with the Payment Card Industry (PCI) Data Security Standard at the time it was breached, banks and credit unions will have a hard time getting it to pay their breach-related costs, according to a Gartner analyst.

PCI standards refer to a set of 12 broad security controls that all entities accepting payment card transactions are required to follow. The standards are mandated by Visa, MasterCard and other major credit card brands and provide for hefty fines against companies that fail to implement the mandated controls and then suffer a breach. The PCI requirements went into effect about two years ago, though many companies are still not fully complaint. (Compare Network Auditing and Compliance products)

Scarborough, Maine-based Hannaford has said it was PCI compliant at the time it was breached. It disclosed on March 17 that unknown intruders had broken into its computer networks and stolen credit and debit card information on 4.2 million customers. The company said the theft appears to have happened during the transaction-authorization stage, which occurs after a payment card has been swiped at a register. The stolen information includes card numbers and expiration dates.

Hannaford spokeswoman Carol Eleazer Thursday said the company was certified as being compliant with PCI as recently as this February. Hannaford had been similarly certified last year, as well, Eleazer said.

If true, Hannaford has a safe harbor under PCI, and will not be required to reimburse banks and credit unions for any breach-related costs they may incur, according to information Gartner analyst Avivah Litan said she has previously received from Visa. Typically under PCI rules, if a company is non-compliant at the time of a beach, it faces two potential costs: fines from the payment card companies and reimbursements of breach-related costs sustained by card-issuing banks and credit unions. Those costs can include payment of fraud losses resulting from the use of compromised payment card data as well as breach notification and the costs associated with reissuing cards.

The fines and the reimbursement costs are not collected directly from the breached entity but through the 'acquiring bank' that authorizes a company such as Hannaford to accept payment card transactions Under PCI rules, it is these acquiring banks that are directly responsible for ensuring that their merchants are PCI compliant.
