When are merchants required to use a PA-DSS validated POS (point-of-sale) application?
December 3rd, 2010 | Posted by in Compliance | PCI - (0 Comments)In True’s experience as a QSA advising merchants with PCI compliance, one point of confusion seems to always surface – when are merchants required to use a Payment Application Data Security Standard (PA-DSS) validated POS application?

Try this little experiment: Google for “Penetration Testing” and try to determine the scope, and more importantly, the goal of a penetration test. Go ahead, I’ll wait …. Confused yet? The vast array of methods, styles, and differing goals can be overwhelming. Even security experts themselves don’t agree on what the purpose or goal of a penetration test should be.Read more
