Security Stats
Stats are from the Verizon Business Data Breach Investigations Report http://www.verizonbusiness.com/resources/security/databreachreport.pdf
Data Breaches
Payment Card Data - Most Wanted
Companies unaware of breach occurance
Exploitation
Hacking and Malicious Code Top for Exploitation Methods
Applications and OS targeted by Attackers
Threat Points
Online presence increased risk
Don't underestimate the insider threat
Simples
Companies unaware of data existence
Attacks are easy to carry out, and many could have been prevented
Why PCI:DSS ??
In the Media
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
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 mandatorymandatory• 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
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
Who’s Who
What does PCI:DSS mean to you?
PCI:SS RequirementsBuild and Maintain a Secure NetworkBuild and Maintain a Secure Network•Install and maintain a firewall configuration to protect cardholder data•Do not use vendor-supplied defaults for system passwords and other parameters
Protect Cardholder DataProtect Cardholder Data•Protect stored cardholder data•Encrypt transmission of cardholder data across open, public networks
Maintain a Vulnerability Management ProgramMaintain a Vulnerability Management Program•Use and regularly update anti-virus software•Develop and maintain secure systems and applications
PCI:SS RequirementsImplement Strong Access Control MeasuresImplement Strong Access Control Measures•Restrict access to cardholder data by business need-to-know•Assign a unique ID to each person with computer access•Restrict physical access to cardholder data
Regularly Monitor and Test NetworksRegularly Monitor and Test Networks•Track and monitor all access to network resources and cardholder data•Regularly test security systems and processes
Maintain an Information Security PolicyMaintain an Information Security Policy•Maintain a policy that addresses information security
Steps to becoming Compliant
Merchant Requirements
Self Assessment Questionnaire
• Subset of the full Onsite Audit Criteria• Completed by the merchant• Submitted to the Acquirer• Made up of Yes / No / Not Applicable
responses• Broken up into the six sections of requirement
Compliance Life Cycle
Pre-Assessment / Gap Analysis
Implement / Remediate
PCI:DSS Certification
Road to compliance
• Senior Manager Support• Understand the task at hand• Identify applications and locations of cardholder
data• Produce network diagrams and data flows• Identify compliance gaps to the 12 requirements• Obtain required expertise• Establish the scope for compliance• Engage with 3rd parties• Conduct vulnerability scans• Prioritise remediation activities• Clarify compliance on submission of SAQ
Key Controls
Systems / TechnologySystems / 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)
Key Controls
ProceduresProcedures• 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
PeoplePeople• Background Checks, Security Awareness
What’s in Scope?
Firewalls / Switches / Routers / Network Appliances / Servers / Workstations / Laptops
PA-DSS Payment Application Data Security Standard
• Based on Visa’s (Payment Application Best Practices) Required 1Required 1stst July 2010 July 2010
Purpose and scopePurpose and scope• Payment applications must facilitate (not
prevent) PCI:DSS compliance• Applies only to payment applications developed
by 3rd parties
Goals for Software DevelopmentGoals for Software Development• Application must not retain mag stripe data• Application must encrypt cardholder data• Guidance for PCI:DSS compliant
implementation
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
Assessment Examples
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
Consequence of non compliance
• Monthly fine for non compliance• Increased cost for processing cards• Damage to brand reputation• Customers sue for negligence• Increased risk of security breach• Costly investigative charges• No safe harbour• Acquirer refuses to allow card processing
Misconceptions
• Self assessment means your compliant• Compliance means you wont suffer a breach• Outsourcing takes away your need for
compliance• PCI:DSS is just about IT• A single product can make you compliant• Compliance can be automated
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
