As an auditor, I am constantly approached by my clients desperately wanting to know if efficiencies can be obtained within the audit and assessment process for companies undergoing both a SAS70 audit and a PCI DSS assessment. There’s no simple yes or no, black or white answer to this, as many variables come into play when conducting a SAS70 audit or a PCI DSS assessment for organizations.
What I can tell you though is that there are some common themes and drivers seen in both a SAS70 audit and a PCI DSS assessment. Both a SAS70 audit and a PCI DSS assessment rely heavily on the existence of documented policies & procedures. Furthermore, both of these examinations also examine various aspects of physical security, network security, logical security, change management, to name a few. Quickly, you can see some overlapping themes in both a SAS70 audit and a PCI DSS assessment. So, that’s the YES answer to “audit efficiencies can be obtained” when a company has to undertake a SAS70 audit and a PCI DSS assessment. So, what’s the NO or the gray erea? Keep in mind that the PCI DSS assessment is a very technical examination, much more so than a SAS70 audit. At the same time, a SAS70 audit also covers comprehensive business process controls applicable to that specific entity being examined for a SAS70. A PCI DSS assessment does generally not cover or assess these specific business processes that a SAS70 would. Thus, you can see the gaps between these two examinations.
