1 Volume 2, April 2011 Come join the discussion! Pritam Bankar and Sharad Verma will be responding to questions and comments in the discussion area of the COBIT Use It Effectively topic beginning 21 April Mapping PCI DSS v2.0 With COBIT 4.1 By Pritam Bankar, CISA, CISM, and Sharad Verma In today s era, every organization across the globe, regardless of its size or industry, faces security issues pertaining to new and evolving threats, vulnerabilities, risks or regulatory/compliance landscapes. As such, there arises a need for organizations to make stringent efforts to ensure that their security and enterprise risk management (ERM) programs address multiple compliance requirements. This article contains the results of a mapping of Payment Card Industry Data Security Standard (PCI DSS) v2.0 controls with COBIT 4.1. PCI DSS is a set of comprehensive requirements for enhancing payment account data security. It was developed by the founding payment brands of the PCI Security Standards Council, including American Express, Discover Financial Services, JCB International, MasterCard Worldwide and Visa Inc., to help facilitate the broad adoption of consistent data security measures on a global basis. This mapping provides guidance to organizations seeking PCI compliance by identifying and highlighting the COBIT areas that should be considered for each requirement within PCI DSS. It also highlights how the processes in COBIT can support PCI DSS compliance activity. As a result, the mapping can be used as a reference for formulating an integrated and customized control framework for an organization. Since COBIT covers the broad spectrum of IT control processes and PCI DSS is strictly focused on protecting cardholder data, any user of COBIT must first determine the relevance and applicability of IT processes and subprocesses within the COBIT framework. COBIT, a framework for the governance of enterprise IT (GEIT), has a broader scope and is applicable to all organizations, whereas PCI DSS v2.0 focuses more on the area of protecting cardholder data and is applicable to all organizations that hold, process or exchange cardholder information. PCI DSS controls are mandatory for organizations that collect credit card data, whereas COBIT has general controls that can be leveraged based on an organization s requirements. The implicit benefits of mapping PCI DSS v2.0 with COBIT include: A unique set of controls Organizations planning to implement PCI DSS can easily manage, measure and provide evidence of satisfying multiple compliance and governance requirements through a single unique set of controls. Adherence to multiple standards Organizations can adhere to multiple industry standards for securing credit card data by adopting the unique set of controls and can increase operational efficiency. Increased performance Each PCI DSS control and requirement is mapped extensively with COBIT controls after assessing the in-depth objective of the control, which results in increasing the performance efficiency of the security program. PCI DSS compliance made easy While compliance with PCI DSS is mandatory for organizations that process financial transactions through payment cards, its scope is limited to protecting cardholder data. However COBIT is like an integrator for best practices and an umbrella framework for IT governance designed to apply across a variety of organizations, and it is universally recognized. For certain enterprises, PCI compliance is mandatory, and COBIT is used as a guideline. Figure 1 provides a mapping of PCI DSS v2.0 to COBIT 4.1. Please note that multiple PCI DSS requirements can map to a single control in COBIT 4.1, as seen in requirements 11 and 12.

Complying with PCI DSS v2.0 along with COBIT 4.1 controls, the organization can work efficiently with IT compliance and IT governance. PCI DSS v2.0 focuses on the compliance area, and COBIT 4.1 provides the overall governance. PCI DSS v2.0 gives a detailed description of a number of important IT controls that can be applied to achieve compliance for the organization dealing with payment card transactions and storing customer information. COBIT provides managers, auditors and IT users with a set of generally accepted measures, indicators, processes and best practices to assist them in maximizing the benefits derived through the use of IT and in developing appropriate IT governance and control in an organization.
