The Missing Piece In PCI: System Resellers

Written by Walter Conway
February 29th, 2012

A 403 Labs QSA, PCI Columnist Walt Conway has worked in payments and technology for more than 30 years, 10 of them with Visa.

PCI compliance covers merchants, their service providers and the software applications both use. However, application resellers and system integrators—each of which plays a critical role in many retailers’ security and PCI compliance—seem to have slipped through the cracks.

PA-DSS requires software providers to educate “customers, resellers and integrators on how to install and configure the payment applications in a PCI DSS-compliant manner.” PA-DSS requirements also address actions resellers and integrators must take to ensure the implementation is PCI compliant. My questions are: Who is checking? And assuming the training is sound, who is checking that the actual tech rep fixing your POS system knows what she/he is doing?

“It is the merchant’s responsibility to make sure they are asking the right questions” of their reseller/integrator, Executive Director of the PCI Security Standards Council Bob Russo said on Tuesday (Feb. 28).

In his comments Russo accepted that resellers/integrators fall into a “hole” between merchant and service provider definitions and that this is “an area we are looking at.” He continued: Retailers “go to resellers thinking their problems will be solved. We [the PCI Council] are not an Internet destination for them.” The PCI Council’s most likely response will be to expand its already extensive—and growing—training initiatives to build PCI awareness among resellers and integrators.

Resellers and integrators sell, install and/or service payment applications for software vendors. They are responsible for implementing the application in a PCI-compliant environment, configuring it according to the PA-DSS Implementation Guide (IG) and maintaining it in a PCI-compliant manner.

To make sure all this happens, PA-DSS Requirement 13.2 requires software vendors to have training and communication programs so resellers and integrators know how to implement the application and its related systems and networks according to the IG and in a PCI DSS-compliant manner.

Appendix A of the PA-DSS spends seven pages detailing the implementation and maintenance requirements that apply to resellers and integrators. These requirements range from deleting old data stored by previous versions of the application to having unique IDs, managing encryption keys and implementing automated audit trails.

Good software vendors and their resellers/integrators take their responsibilities seriously.

    As a follow-up to the column, I learned that Visa has a Best Practices document for resellers and integrators on their website. Retailers (and anyone) can go here and take a look at what Visa is telling resellers and integrators to do when they work on a merchant site:

    It looks like a very good list, and thanks to the SFBT reader who brought this to my attention. Merchants can use the best practices, too, to make sure they get all they are paying for.

Why Did Gonzales Hackers Like European Cards So Much Better?

I am still unclear about the core point here-- why higher value of European cards. Supply and demand, yes, makes sense. But the fact that the cards were chip and pin (EMV) should make them less valuable because that demonstrably reduces the ability to use them fraudulently. Did the author mean that the chip and pin cards could be used in a country where EMV is not implemented--the US--and this mis-match make it easier to us them since the issuing banks may not have as robust anti-fraud controls as non-EMV banks because they assumed EMV would do the fraud prevention for them Read more...
Two possible reasons that I can think of and have seen in the past - 1) Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code. 2) Also, in offline chip countries the card determines whether or not a transaction is approved, not the issuer. In my experience, European issuers haven't developed the same checks on authorization requests as US issuers. So, these cards might be more valuable because they are more likely to get approved.

A smart card slot in terminals doesn't mean there is a reader or that the reader is activated. Then, activated reader or not, the U.S. processors don't have apps certified or ready to load into those terminals to accept and process smart card transactions just yet. Don't get your card(t) before the terminal (horse). Read more...
The marketplace does speak. More fraud capacity translates to higher value for the stolen data. Because nearly 100% of all US transactions are authorized online in real time, we have less fraud regardless of whether the card is Magstripe only or chip and PIn. Hence, $10 prices for US cards vs $25 for the European counterparts. Read more...
@David True. The European cards have both an EMV chip AND a mag stripe. Europeans may generally use the chip for their transactions, but the insecure stripe remains vulnerable to skimming, whether it be from a false front on an ATM or a dishonest waiter with a handheld skimmer. If their stripe is skimmed, the track data can still be cloned and used fraudulently in the United States. If European banks only detect fraud from 9-5 GMT, that might explain why American criminals prefer them over American bank issued cards, who have fraud detection in place 24x7. Read more...
