Payment Card Industry Data Security Standard
What is PCI DSS?
PCI DSS stands for Payment Card Industry Data Security Standard. This
standard is a set of controls to protect cardholder data by mitigating data
breaches and preventing cardholder data fraud.
Defined by the Payment Card Industry Security Standards Council (PCI
SSC) , the standard was created to increase controls around cardholder
data to reduce credit card fraud.
All merchants, processors, acquirers, issuers, service providers, and other
entities that store, process or transmit cardholder information are required
to comply with the PCI DSS.
PA-DSS vs. PCI DSS?
The Payment Application Data Security Standard (PA-DSS) requires vendors
who supply payment application software to validate the application with
the PCI Council. The validated application must be placed or used in a PCI
DSS compliant environment for full compliance to be achieved. The
merchant is responsible for the compliant environment.

Roles and Responsibilities
Merchant
•
Adhere to the PCI DSS standard.
•
Create a corporate security strategy to become and stay PCI compliant.
•
Create and maintain a compliant infrastructure.
Acquiring Bank
•
Provide support, advice, and general guidance on PCI.
•
Ensure any products, software, or gateways added or in use are certified as PCI compliant.
•
Quarterly reporting to the card brands on a merchant’s compliance status.
–
This reporting reflects date and status of the SAQ/ROC, scan date(s) and results,
information from the merchant completed Prioritized Approach containing the areas of
non-compliance with current percentage completed and expected completion dates for
full compliance.
Card Networks/Brands
•
Enforcement of compliance with the PCI DSS and determination of any non-compliance
penalties are carried out by the individual payment brands and not by the Council or WFMS.
PCI Data Security Council
•
An open global forum, launched in 2006, is responsible for the development, management,
education, and awareness of the PCI Security Standards, including the Data Security
Standard (PCI DSS), Payment Application Data Security Standard (PA-DSS), and PIN
Transaction Security (PTS) requirements.
•
The Council's five founding global payment brands -- American Express, Discover Financial
Services, JCB International, MasterCard Worldwide, and Visa Inc. -- have agreed to
incorporate the PCI DSS as the technical requirements of each of their data security
compliance programs and have equal input. Each founding member also recognizes the
QSAs, PA-QSAs and ASVs certified by the PCI Security Standards Council.

Don’t Delegate Compliance
• Never assume your software vendor or service provider
is maintaining your PCI Compliance
• You should be able to answer the following questions:
– What equipment, software, and services do we use for
processing and where are they located?
– Do we have a complete inventory?
– Do we have a hardware based firewall?
– What anti-virus software do we use and who updates it?
– Do we have remote access software on our system?
– Is it always turned on?
– Is 2 factor authentication used?
– Is there one id and password per individual user?
– Are passwords changed regularly?
– Who reviews our log files?
– Who trains the employees to follow guidelines & how?
– Can we document everything PCI related?

Maintenance is Key
• Data security is more than completing a SAQ
every 12 months
• Begin SAQ at least three months before its due
• Stay up to date
– PCI council changes
– Payment network mandates
– The latest trends in data compromise
• Scan
–
–
–
–
Complete a passing external scan at least quarterly
And every time changes are made to the system
Use internal scans to detect and correct vulnerabilities
Daily review that Anti-Virus, File Integrity Monitoring,
and Logging are running

Chip & PIN– a.k.a EMV
• Near Field Communication (NFC)
• Required vs. Encouraged
– Liability Shift in the U.S. effective October 1,
2015
– Merchants not using EMV will take the financial hit
on fraudulent, card-present transactions.
• Benefits
– Physical Cards are less likely to be used
fraudulently.
• Compliance
– No changes in compliance requirements.
• Disclaimer
– E-Commerce/Phone transactions not affected.17

You may validate to version 2.0 through the end of the year.
Mandatory use of 3.0 for validations in 2015
•
*Standards are updated due to the need for additional guidance,
clarification, or evolving requirements for strong security standards.

End to End Encryption
• Point to Point Encryption ≠ E2EE
– PCI DSS terminology
– Must be an approved hardware/software
combination
• Scope Reduction
– SAQ D – most requirements are not applicable
• Hardware Encryption is VITAL!
– Integration with Gateway, Software, Hardware
• Always seek Acquiring Bank & QSA approval
19
Mobile Payments – PCI DSS
Mobile Payments
February 2013 - The PCI Security
Standards Council has published
the PCI Mobile Payment
Acceptance Security Guidelines for
Merchants as End Users. This
guide educates merchants on the
risk factors that need to be
addressed in order to protect card
data when using mobile devices to
accept payments.
Guidelines to Consider
– Single purpose tablets, iPads
– Hot Spot vs WiFi
– Reduced functionality
(browsing)
– End to End Encryption
Devices
– Acquiring Bank products
– Banking Policy

Consequences and Penalties for
Non-Compliance or Breach
The consequences and costs of non-compliance and of a data
compromise can be devastating and may include:
•
Loss of the ability to process card payments.
•
Loss of consumer confidence and brand reputation.
•
Drop in revenues.
•
Heavy fines, penalties and expenses.
-
Up to $500,000 a month per violation
(payment network imposed fines).
-
Actual damages to cardholders.
-
Attorneys’ fees.
-
Potential state and federal fines.
Notification and Remediation Process
•
Merchant reports suspected or known breach to Bank upon findings and card
brands are notified.
•
Card brands notify Bank of Common Point of Purchase investigation.
•
Remediation requires demonstration, documentation, and deadlines. Costly
forensic investigation may be required.
•
In some cases, you may be required to shut down all POS, gateways, or IP
connected terminals and install “dial-up” terminals until the environment is
remediated and deemed safe.
Data breaches
now cost
$194 per
compromised
record
and averaged
$5.5 million
per data
breach
event.*

Payment Card Industry Glossary
ASV Acronym for “Approved Scanning Vendor.” Company approved by the PCI SSC to conduct external
vulnerability scanning services.
Cardholder Data At a minimum, cardholder data consists of the full PAN. Cardholder data may also appear in the
form of the full PAN plus any of the following: cardholder name, expiration date and/or service code See Sensitive
Authentication Data for additional data elements that may be transmitted or processed (but not stored) as part of a
payment transaction.
Environment The people, processes and technology that store, process or transmit cardholder data or sensitive
authentication data, including any connected system components.
Compensating Controls Compensating controls may be considered when an entity cannot meet a requirement
explicitly as stated, due to legitimate technical or documented business constraints, but has sufficiently mitigated
the risk associated with the requirement through implementation of other controls. Compensating controls must:
•
(1) Meet the intent and rigor of the original PCI DSS requirement; (2) Provide a similar level of defense as the
original PCI DSS requirement; (3) Be “above and beyond” other PCI DSS requirements (not simply in
compliance with other PCI DSS requirements); and (4) Be commensurate with the additional risk imposed by
not adhering to the PCI DSS requirement.
Network Segmentation Network segmentation isolates system components that store, process, or transmit
cardholder data from systems that do not. Adequate network segmentation may reduce the scope of the cardholder
data environment and thus reduce the scope of the PCI DSS assessment.
P2PE Point to Point Encryption.
Penetration Test Penetration tests attempt to exploit vulnerabilities to determine whether unauthorized access or
other malicious activity is possible. Penetration testing includes network and application testing as well as controls
and processes around the networks and applications, and occurs from both outside the network trying to come in
(external testing) and from inside the network.
QSA Acronym for “Qualified Security Assessor,” company approved by the PCI SSC to conduct PCI DSS on-site
assessments.
Sensitive Authentication Data Security-related information (including but not limited to card validation
codes/values, full magnetic-stripe data, PINs, and PIN blocks) used to authenticate cardholders and/or authorize
payment card transactions.
