Even though the PCI Security Standards Council's validation requirements for Qualified Security Assessors states that QSAs must act ethically and independently by limiting sources of influence that may compromise their independent judgment during a PCS DSS assessment, conflicts of interest can and do happen.
According to Gartner Inc.'s top expert on PCI DSS, the PCI assessment process is rife with conflicts of interest because QSAs can too easily benefit from the results of their assessments.
"It's not a good idea to have an auditor come in, find the problem, and say, 'By the way, we can sell you the solutions to fix the problems,'" said Avivah Litan, vice president and distinguished analyst with the Stamford, Conn.-based research firm. "It's just an inherent conflict of interest."
In this interview, conducted at the 2014 Gartner Security & Risk Management Summit, Litan discusses PCI conflict of interest issues, why they ultimately harm enterprise payment data security, and the "really simple" solution that could eliminate the problem once and for all.
Litan also discusses why the infamous Target Corp. data breach represented a turning point for enterprise information security, and how it has triggered a rapid move toward chip and PIN payment systems. Finally Litan analyzes whether the new Retail Information Sharing & Analysis Center (ISAC) will help reduce the risk of retail data breaches, and what it will take for retailers to volunteer to share information with others.
