9. Why PCI:DSS ??

10. In the Media

11. The Creation of PCI:DSS • Payment Card Industry : Data Security Standard • Card Fraud pushed to an unsustainable level • Security of information is an important factor to protect against financial loss, as well as reputational loss • PCI:DSS is the card schemes response • Secure transmission, storage and processing of card holder data. • Coverage of systems, policies, and procedures

12. What's it all about? • Increase security of card holder data • Coverage of entire payments process • Backing from the card schemes and banks • Compliance is mandatory • Based on best practice • Over 232 controls in 12 areas • June 2005 Deadline • July 2007 Deadline • All merchants to define a compliance date • 18% of companies in the UK are compliant

13. What can PCI:DSS Do For You? • Brand reputation protection • Framework to build upon • Understanding of information in your business • Improved security controls • Documented and formalised process and policy • Acceptance and reduction of risk • Competitive edge • Reduced processing costs • Avoid fines and legal costs • Continue accepting cards • Safe Harbour

23. Key Controls Systems / Technology • Network Segmentation • System Hardening • Encryption • Anti-Virus / Anti-Malware • Access Controls • Password Controls • Physical Access Controls • Centralized Logging • File Integrity Monitoring • IDS / IPS • Scanning (Wireless & Vulnerabilities)

24. Key Controls Procedures • Systems Build • Encryption Key Management • Secure Applications Development • Security Testing (Vuln Scanning & Pen Tests) • Log Review • Annual Risk Assessment • Policies / Procedures Annual Review & Issue • Security Awareness • Incident Response Annual Testing People • Background Checks, Security Awareness

25. What’s in Scope? Firewalls / Switches / Routers / Network Appliances / Servers / Workstations / Laptops

26. PA-DSS Payment Application Data Security Standard • Based on Visa’s (Payment Application Best Practices) Required 1st July 2010 • Purpose and scope • Payment applications must facilitate (not prevent) PCI:DSS compliance • Applies only to payment applications developed by 3rd parties • Goals for Software Development • Application must not retain mag stripe data • Application must encrypt cardholder data • Guidance for PCI:DSS compliant implementation

27. QSA Review / Assessment • Detailed audit against PCI:DSS • Targets all systems and networks storing, processing or transmitting cardholder data • Review of contractual relationships • Performed by a VISA certified provider (QSA) • Report on compliance submitted to Acquirer

28. Assessment Examples

29. Common Compliance Issues • Scoping of project is to large • Flat network and no segmentation • Legacy systems, and non compliant software • Lack of knowledge to interpret controls • Lack of formal processes and procedures • Confusion of systems scoping • Storage, processing and transmitting of data with no business requirement • Non compliant 3rd parties • Significant cost to full compliance • Evaluation of compensating controls

Tips and Take Aways • Reduce your scope • Ensure senior buy in • Prioritise Tasks – High Medium Low • Be honest and open about card holder data existence • Maintain the good security practices • Go beyond card data systems • Be proactive with checks and controls • No single product equals compliance • Make someone responsible for managing compliance
