PCI QSA Done!

Posted on 2008 10, 08 by Talha

Finished my second and last day of PCI (Payment Card Industry) training in Puerto Rico and “almost” become a Qualified Security Assessor (QSA). The training session ended with a short exam, the result of which will be announced in around within 2 weeks, and after which I will be be allowed to conduct PCI audits.

The PCI is a council formed by Visa, MasterCard, American Express, JCB and Discover and their basic function is to define and review security standards, so that the merchants and their service providers can secure their infrastructure to minimize the theft of credit card data.

The course contained both boring compliance stuff to really interesting things like what exact data is stored on the magnetic stripes of credit cards as well as how to mathematically compute the credit card number to validate it.
