Two Approaches to PCI-DSS Compliance EDUCAUSE Security Professionals Conference April 11, 2006
Agenda What is PCI-DSS? Bringing a University into Compliance Maintaining Compliance Q & A
What is PCI-DSS? Brief history of credit card infosec regulation Who must comply? Consequences of non-compliance Review of “Digital Dozen”
Data Security Standard PCI DSS History - 2000 2004 Visa Cardholder Information Security Program (CISP) Mastercard Site Data Protection Program (SDP) Payment Card Industry Data Security Standard (PCI DSS) Discover Information Security Compliance Program (DISC) American Express Data Security Standard (DSS)
Who Must Comply? “Payment Card Industry (PCI) Data Security requirements apply to all Members, merchants, and service providers that store, process or transmit cardholder data.” “Additionally, these security requirements apply to all system components which is defined as any network component, server, or application included in, or connected to, the cardholder data environment.” Hopefully, That Doesn’t Mean You! That Probably Means You
Merchant Levels Merchant Level Description 1 Any merchant who processes over 6,000,000 transactions annually. Any merchant that has suffered a breach. Any merchant designated Level 1 by Visa 2 Any merchant who processes between 150,000 and 6,000,000 e-commerce transactions annually. 3 Any merchant who processes between 20,000 and 150,000 e-commerce transactions annually. 4 Anyone else
Merchant Levels All merchants, regardless of level, must comply with all elements of the PCI DSS standard! Merchants at different levels have different validation requirements
Service Providers “Service providers are organizations that process, store, or transmit Visa cardholder data on behalf of Visa members, merchants, or other service providers.”
Consequences Reputational Risk Financial Risk What will the impact be on your institution’s brand? Mandatory involvement of federal law enforcement in investigation Financial Risk Merchant banks may pass on substantial fines Up to $500,000 per incident from Visa alone Civil liability and cost of providing ID theft protection
Consequences Compliance Risk Operational Risk Exposure to Level 1 validation requirements Operational Risk Visa-imposed operational restrictions Potential loss of card processing privileges
What Does Compliance Take?
Introducing the Digital Dozen Install and maintain a firewall Do not use vendor default passwords Protect stored data Encrypt transmissions of cardholder data
Introducing the Digital Dozen Use and update antivirus software Develop and maintain secure systems and applications Restrict access by need-to-know Assign unique IDs to all users
Introducing the Digital Dozen Restrict physical access to cardholder data Track and monitor access to cardholder data Regularly test security systems and processes Maintain an information security policy
Bringing a University into Compliance Seeking assistance from consultants Centralized vs. decentralized approach Conducting a gap analysis Prioritizing remediation Infrastructure vs. tactical remediation
Seeking Assistance Self-Assessment Questionnaire ROC Quarterly network scans (annual L4) On-site assessment (only L1) Penetration test (only L1)
Centralized Approach “If you build it, they will come” One physical location Need space/resources Retail Applications Units will want ability to customize Use 3rd party assessor (ROC)
Decentralized Approach “Divide and Conquer” Maintains autonomy – (good or bad?) Stop-gap Protects investments in technology Flexible – use 3rd party or DIY
Picking an Approach Hybrid is likely Focus efforts – Prioritize! Consider phases Focus efforts – Prioritize! Weakest links Biggest targets Merchant setup not relevant
Conducting a Gap Analysis Top administrative support essential Policy: Comply with PCI-DSS Make friends with your money people
Conducting a Gap Analysis Preliminary meeting Phase 1 – offsite review Phase 2 – analysis Phase 3 – onsite review Reporting and follow up
Gap Analysis - Preliminary Phone call and letter/email first Set expectations Gather information Describe systems IP addresses, locations Software and OS versions, other equipment Share documentation & request it
Gap Analysis – Phase 1 Perform network scans Research Perform system scanning Complete a Self-Assessment
Gap Analysis – Phase 2 Analyze preliminary results Network scans System scans Self-Assessment responses Policy/procedure documentation
Gap Analysis – Phase 3 On-site review Firewall required, appropriately configured Vendor defaults changed Configuration standards Encryption (stored data & transmissions) System maintenance Access Controls, Authentication Physical security Logging and monitoring Policy and procedures
Gap Analysis No surprises Respond with formal report Disperse SAQ, summarize results
Infrastructure vs. Tactical Remediation Goal = infrastructure Centralize Control risk, comply Reality = tactical first Upgrades Configurations Employ encryption
Prioritizing Remediation Network “drive by” attacks Firewall System configuration & maintenance Encryption Access controls Policy and Procedure Trained staff are essential Focus on your biggest risks !!!
Maintaining Compliance Testing Monitoring Audits and Self-Assessments
The Key to Success Scope Management
Testing The standard requires you to conduct vulnerability scans Level 1, 2, & 3 merchants must have them done by a qualified external vendor Standard also requires annual penetration testing
Monitoring Intrusion detection/prevention File integrity monitoring Automated audit trails Daily review One year of history Three months available online
Audits and Assessments Everyone should conduct self-assessments Level 2 & 3 merchants must conduct annual self-assessments Level 1 merchants must conduct annual on-site assessments
Design Review Environments change Critical to introduce security review into: New merchant accounts Vendor selection Architecture modifications
