  • 1. 1WhitepaperPCI Compliance: Protect Your Business fromData BreachThe security and safety of personal and financial data is increasinglythreatened. Nowhere is that more apparent than in the retail industry—a primary target for cyber criminals.Retail businesses are particularly vulnerable because of the volume of creditcard information, the fact that this information is distributed among manylocations, the lengthy amount of time it can take them to detect a breach,and the often inadequate staff and safeguards they have in place.Some experts forecast that as many as one in six small businesses will bebreached.1Small businesses are particularly vulnerable; according to Visa,97% of U.S. events occurred at small merchants, and 91% of those werebrick and mortar merchants.2Larger organizations, too, are vulnerable to the consequences of such abreach. Examples from recent years include Bank of America, Boston Market,Sports Authority, and Forever 21. A particularly devastating case was thebreach of TJX Corp., which resulted in the loss of at least 45 million creditcard numbers to a single hacker.Merchants often underestimate the financial impact of a breach, which canbe significant. Smaller retailers that suffer a major and widely publicizedbreach of credit card data may actually find themselves out of businessdue to costs associated with fees, fines, and remediation, as well asongoing damage to their brands and reputations.For example, the average cost of a breach is estimated at $80,000 perlocation for Level 4 merchants, and can reach into the millions dependingon the size of the merchant and the extent of the breach.3Direct costs includemandatory forensic audits, credit card replacement, fees, fines, and breachremediation to prevent a recurrence.PCI COMPLIANCE IS ESSENTIAL FOR SECURE TRANSACTIONSAND FINANCIAL STABILITYMerchants oftenunderestimate thefinancial impact of abreach. Direct costsinclude mandatoryforensic audits, creditcard replacement,fees, fines andbreach remediation.
  • 2. 2WhitepaperFor these reasons, complying with PCI-DSS (Payment Card Industry DataSecurity Standard, also known simply as PCI) is much more than just atechnical goal for retailers. It is necessary for business stability.PCI was originally created as a joint initiative by Visa, MasterCard,American Express, JCB, and Discover to protect card-holder informationand reduce data theft and fraud. The first version was released inDecember 2004, and it has since then undergone two significantupdates. The current version, 2.0, was issued in October 2010.PCI compliance is mandatory for all organizations who accept Visaand MasterCard credit cards. If a retailer is found to be noncompliant,it could incur significant fines and be restricted from accepting creditcards until compliance is achieved.While no standard can guarantee 100% prevention of a majorcredit card data breach, PCI compliance can significantly reduce theprobability of such an event. Being PCI compliant means that merchantsare pursuing established best practices specifically designed to protectsensitive credit card data from unauthorized access—critical both forthemselves and their customers.What is PCI-DSS?Table 1: Typical Breach/Remediation TimelineDay 1Notification of breachStop taking credit cardsPay for a forensic auditMonitor media/social mediaDay 5Forensic audit completeContact a Qualified Security Assessor (QSA)Day 7Obtain proposals for remediationDay 10 toDay 40 -180Execute remediation and compliance planReplace credit cardsDisclose breach/address brand and media impactPost breach plus one year - revenue impactBreach remediation can take months, as shown in Table 1. For these reasons,complying withPCI-DSS (PaymentCard Industry DataSecurity Standard,also known simplyas PCI) is much morethan just a technicalgoal for retailers.It is necessary forbusiness stability.
  • 3. 3WhitepaperAll members of the PCI payment card network, including merchants andservice providers, must comply with 12 different requirements organizedinto six core categories:Source: PCI DSS Requirements and Security Assessment Procedures, Version 2.0,https://www.pcisecuritystandards.org/documents/pci_dss_v2.pdfPCI DSS RequirementsBuild and Maintain a Secure Network1. Install and maintain a firewall configured to protect card-holder data.2. Do not use vendor-supplied defaults for system passwords and other security parameters.Protect Card-holder Data3. Protect stored card-holder data.4. Encrypt transmission of card-holder data across open, public networks.Maintain a Vulnerability Management Program5. Use and regularly update anti-virus software or programs.6. Develop and maintain secure systems and applications.Implement Strong Access Control Measures7. Restrict access to card-holder data within the organization on the basis of businessneed-to-know.8. Assign a unique identifier to each employee with computer access.9. Restrict physical access to card-holder data.Regularly Monitor and Test Networks10. Track and monitor all access to network resources and card-holder data.11. Regularly test security systems and processes.Maintain an Information Security Policy12. Maintain a policy that addresses information security for all employees.• Can you demonstrate that all of your cashiers have been trained uponhire with a PCI-certified training program, and does that training recurevery year?• Can you demonstrate that all of your employees have read and signedan employee awareness security policy?• Can you demonstrate that all members of your team or your approvedvendors are using a secure virtual private network with two-factorauthentication to access applications or systems behind your firewall?Most retailers are aware of the importance of PCI compliance, but manylack the essential safeguards required to fully achieve it.For example, when retailers who accept credit cards are asked thefollowing questions, frequently at least one answer is “no,” indicatingthat they are not compliant:What is required for PCI compliance? All members of thePCI payment cardnetwork, includingmerchants andservice providers,must comply withtwelve differentrequirementsorganized into sixcore categories.
  • 4. 4WhitepaperOn-Site Security Audit: Required for Level 1 merchants, this is alsoknown as a Report on Compliance (ROC) and must be completedby a PCI-certified Qualified Security Assessor (QSA).Annual Self-Assessment Questionnaire: In lieu of a ROC, Level 2-4merchants must complete one of six Self-Assessment Questionnaires (SAQ)to document PCI compliance status. This must recur annually to identifycompliance shortfalls.Quarterly External Vulnerability Scans: All merchants are required tohave external network scans performed by a PCI-certified Authorized-Scanning Vendor (ASV). Scan requirements are rigorous: all 65,000ports must be scanned, vulnerabilities detected, “high” severity-levelvulnerabilities must be remediated, and two key reports completedand filed with the bank card processor.As this chart shows, merchant validation requirements fall into three groups:PCI compliance is not a one-time achievement, but is validated on anongoing basis. The terms of validation vary based of the total number ofannual credit card transactions that merchants generate each year, andare organized into four levels:Level CriteriaOn-SiteSecurityAuditSelf-AssessmentQuestionnaireExternalVulnerabilityScan1.

  • 6. 6WhitepaperRetail business success depends upon secure credit card transactions andthe protection of sensitive customer data.Unfortunately, the odds of a security breach grow every year, as hackers,criminal organizations, and malware all grow more sophisticated andaggressive. And in the event that a breach occurs and results in the lossof sensitive credit card information — the consequences could be veryserious, from fiscal, legal, and/or public relations standpoints.Compliance with the PCI-DSS, an end-to-end standard addressingboth technology and business processes, is essential to make suchbreaches far less likely. It’s also legally required for all retailers thattake Visa or MasterCard.PCI-DSS is a complex standard, however, and one that requires ongoingvalidation to remain in compliance. Many organizations will find thatby collaborating with a trusted partner, achieving and maintaining PCIcompliance can be both simplified and accelerated. EarthLink Businessdelivers the tools, experience, and service to help retailers achieve,maintain, and validate PCI-DSS compliance requirements.Notes:1.
