PCI and Fraud Analysis: To Have and Have Not

May 26th, 2009
As merchants work to reduce the scope of PCI compliance and the risk due to having credit card data in their environment, some companies are actually taking access to this data away from people who need it to do their job, including the managers who are charged with investigating fraudulent credit card transactions. Instead of PCI controls helping reduce fraud, for some companies, they are making fraud detection more difficult.

"We all know that PCI compliance creates dividing lines," said GuestView PCI Columnist David Taylor. "Flat networks must be segmented. The number of databases that store—and applications that use—cardholder data needs to be reduced and the number of persons with full card number access needs to be reduced as well. The whole process of separating the “haves” from the “have nots” often leads to arguments and requires extensive justification on the part of those who maintain they must have the ability to see unencrypted card data in order to do their job."

"Careless" Systems Integrators Now Directly Under PCI DSS

This exact issue has been bothering me for years, and I was JUST talking about it with someone only yesterday. This may well be my favorite article, mostly because I'm biased and have hated this particular problem forever. Read more...
Good article, but how does this have anything to do with the DSS? Read more...
Actually, the QIR program has a lot to do with the DSS (or PCI). Since merchants rely on their reseller or integrator to implement their PA-DSS validated application, these resellers and system integrators play a critical role in merchants achieving and maintaining PCI compliance. As far as I can tell, the QIR program is designed to help merchants stay compliant by making sure their payment applications are installed according to the PA-DSS Implementation Guide, for example ensuring default passwords are changed (and protected), that the data encryption keys are properly set and secured, that the merchant's data retention policy is set, that no sensitive cardholder data are stored, and often that a firewall is in place and properly configured.

Although this is a great move forward in pushing the issue of highly trained people, it is also a good marketing ploy for the council. It begs the question: How much do they stand to make? The problem for this is that for people (like myself) that are just starting out their own business venture, PCI has typically charged a premium for their training and certifications. This change will likely force those of us with less capital to spin into the abyss. I have more than 15 years in the security and compliance fields with heavy hitter certs like CISSP, CRISC, and Sec+. There should not be a guide but a free test or a pre-requisite of either the PCI cert OR other heavy hitter certs. I just don't want the good guys in small places to get flushed out. Read more...
