The Problem

Albert Gonzalez, 28

With accomplices, he was involved in data breaches of most of the major data breaches: Heartland, Hannaford Bros., 7-Eleven, T.J. Maxx, Marshalls, BJ’s Wholesale Club, OfficeMax, Barnes & Noble, Sports Authority, Dave & Busters, Boston Market, Forever 21, DSW and others.

Alarming Trend

Number of incidents per year.

Players• Acquirer (Merchant Bank)

– Bankcard association member that initiates and maintains relationships with merchants that accept payment cards

• Hosting Provider– Offer various services to merchants and

other service providers.• Merchant

– Provides goods and services for compensation

• Cardholder– Customer to whom a card is issued or

individual authorized to use the card

PCI Data Security Standard

What does the PCI Council do?

• Own and manage PCI DSS, including maintenance, revisions, interpretation and distribution

• Define common audit requirements to validate compliance

• Manage certification process for security assessors and network scanning vendors

• Establish minimum qualification requirements• Maintain and publish a list of certified assessors

and vendors

What are the Standards?

• PCI DSS: PCI Data Security Standard– Overall standard, applies to all

• PA DSS: Payment Application Data Security Standard– Supporting standard for payment applications

• PTS (was PED): PIN Transaction Security Standard– Supporting standard for PIN entry devices– Supporting standard for unattended payment

terminals (UPT)

PCI DSS

Standard Lifecycle

Who must comply?

• With PCI DSS– Any organization the processes, stores or transmits credit

card information. • With PA DSS

– Payment application developers– Merchants will be required to use only compliant

applications by July 2010.• With PTS

– Manufactures of PIN entry devices– Merchants will be required to use only compliant

hardware by July 2010.– MasterCard PTS to incorporate into PCI SSC April 30, 2010

PCI Compliance

• This includes: • Organizations who only use paper based

processing• Organizations who outsource the credit

card processing• Organizations that process credit cards in

house

Is PCI law?The PCI DSS was developed by the

payment card brands Compliancy is compulsory if a merchant

wishes to continue processing payment card transactions

However, some States have enacted legislation that has made PCI compliance the law

What if we are a small organization?

• “All merchants, whether small or large, need to be PCI compliant.

• The payment brands have collectively adopted PCI DSS as the requirement for organizations that process, store or transmit payment cardholder data.”– PCI SSC

Cost?• What happens when there is a data

breach?– Depends if the merchant can reach safe

harbor.

What’s Safe Harbor?

Incident

Evaluation

Safe Harbor

$$$$$$

Safe Harbor Notes:

• For a merchant to be considered compliant, any Service Providers that store, process or transmit credit card account data on behalf of the merchant must also be compliant.

• The submission of compliance validation documentation alone does not provide the merchant with safe harbor status.

Outside the Safe Harbor

• Losses of cardholders• Losses of banks• Losses of card brands

– Fines from the Card brands– Possible restrictions on process credit cards– Cost of forensic audit

FinesMerchants may be subject to fines by the card associations if deemed non-compliant. For your convenience fine schedules for Visa and MasterCard are outlined below.

PCI DSS

The Payment Card Industry Data Security Standard 6 Objectives (Goals) 12 Sections (Requirements) 194 Controls

PCI DSS

PCI DSS

• Start implementing the data security standard starting with policies

• Start with high level polices– “The City shall not store PAN (Credit Card

Numbers) electronically or physically. Employees shall be trained on PCI standard annually. Background checks will be performed on all staff with access to credit card information.”

Create Needed Policies

• What policies do you currently have that address PCI related issues

• Create needed policies• See section 12 of the PCI DSS• You will need to create additional subordinate

policies, procedures or administrative directives for specific PCI control requirements

• Every PCI DSS control should be documented in some policy, procedure, administrative directive, SOP or schedule

PII Policy

• If you already have a policy for handling confidential information or personally identifiable information add credit card information to confidential information or PII.

PCI DSS

• Use the prioritized approach to implement the most important controls first.

Merchant Levels

Merchant levels are determined by the annual number of transactions not the dollar amount of the transactions.

Merchant Level E-commerce transactions All other transactionsLevel 1 Over 6 million annually Over 6 million annuallyLevel 2 1 to 6 million annually 1 to 6 million annuallyLevel 3 20,000 to 1 million annually N/ALevel 4 Up to 20,000 annually Up to 1 million annually

Validation Requirements

Merchant Level QSA Audit Quarterly Network Scans

Self-Assessment Questionnaire

Level 1 Yes Yes -

Level 2 * Yes Yes

Level 3 - Yes Yes

Level 4 - Yes Yes

Separate and distinct from the mandate to comply with the PCI DSS is the validation of compliance whereby entities verify and demonstrate their compliance status.* Starting 12-31-2010 MasterCard will require Annual QSA Audits for Level 2 Merchants

Continuous Process

• “PCI DSS compliance is much more than a “project” with a beginning and end – It’s an ongoing process of assessment, remediation and reporting” - PCI SSC

Assess

ReportRemediate

Continuous Process

• Many of the PCI requirements have specific time interval requirements

• Create a schedule for time based requirements

• Some organizations already have ‘maintenance calendars’ for these type of actions

Common Findings

• Clients think they are compliant– Because they do quarterly networks scans– Because they filled out the SAQ– Because they have too few transactions

• Reality– Validation is not compliance– Compliance is an ongoing process– PCI DSS is required for all merchants,

regardless of the number of transactions

Common Findings• Payment card information on paper• No network segmentation• Logging Access• Shared Passwords• Verifying compliance of outsourced

processing• No one is assigned responsibility• Not aware of PAN storage in

application

PCI Pitfalls• PCI will not make an

organization’s network or data secure

• PCI DSS focuses on one type of data: payment card transactions

• The organization runs the risk of focusing on one class of data to the detriment of everything else
