PURPOSE AND APPLICABILITY

These Payment Card Data Security Procedures specify the standards that the University and its departments, offices and units accepting payment card transactions (“merchants”) shall fulfill in order to achieve and maintain compliance with cardholder data protection and security requirements as established in the PCI DSS.

1. The relevant PCI DSS is the current version as released by the PCI SSC. When transitioning from a previous release to the newest release, the University Steering Committee will control the timing of University-wide switchover while adhering to the deadlines for adoption specified in the newest release.

2. These Procedures apply to all University activities that involve any form of payment card handling.

3. PCI DSS applies to all card acceptance arrangements where the proceeds of revenue generating activities received from card-paying customers of the University are ultimately deposited to the University’s bank account for credit to the cost centre of the beneficiary department, office or unit.

4. PCI DSS applies to all merchants that generate revenues by the acceptance of credit cards (Visa, MasterCard, American Express, Discover).

5. Merchants that generate revenues through the acceptance of debit cards (Interac network) are also subject to these Procedures.

6. PCI DSS compliance requirements apply to the handling of credit cardholder data (CHD) and processing.

7. These Procedures apply to:

a. University merchants accepting card payments on University premises and at University events, including mobile operations;

b. University systems, infrastructure and networks when utilized for transacting, transmitting or storing card payments data; and

c. Service providers (third-party suppliers or vendors) that provide applications or services directly or indirectly to a department, office or unit of the University that incorporate payment card acceptance and/or processing.

d. Service provider types include:

i. Payment applications that are incorporated in software or on-line accessed services

ii. Systems and services that accept point of sale or eCommerce card payments on behalf of a University merchant that:
remit proceeds to the University by cheque or electronic funds transfer, or
interface with the University’s acquirer; and

iii. Hosting services that process card transactions for the University or its contracted service provider.

PAYMENT CARD INDUSTRY DATA SECURITY STANDARD (PCI DSS)

8. PCI DSS is a multi-faceted security standard intended to help organizations proactively protect customer account card data encountered as part of their business and information technology activities.

9. Compliance with PCI DSS represents a contractual requirement of the payment brand companies and the PCI SSC that obligates service providers and merchants to meet minimum security standards anywhere they store, transmit and/or process credit card account numbers and other credit cardholder data.

10. The PCI SSC has specified rules that apply to merchants and service providers each involving a series of required validation steps. These are:

Build and Maintain a Secure Network

1 - Install and maintain a firewall configuration to protect cardholder data
2 - Do not use vendor-supplied defaults for system passwords and other security parameters

Protect Cardholder Data

3 - Protect stored cardholder data
4 - Encrypt transmission of cardholder data across open, public networks

Maintain a Vulnerability Management Program

5 - Use and regularly update anti-virus software or programs
6 - Develop and maintain secure systems and applications

Implement Strong Access Control Measures

7 - Restrict access to cardholder data by business need-to-know
8 - Assign a unique ID to each person with computer access
9 - Restrict physical access to cardholder data

Regularly Monitor and Test Networks

10 - Track and monitor all access to network resources and cardholder data
11 - Regularly test security systems and processes

Maintain an Information Security Policy

12 - Maintain a policy that addresses information security for all personnel

11. The University, its merchants and its systems are all required to be in compliance with this standard and are subject to validation at least annually.

SUMMARY REQUIREMENTS FOR COMPLIANCE

23. The primary account number (PAN) is the primary factor defining the applicability of PCI DSS requirements. PCI DSS is applicable when PAN data is stored, processed or transmitted. If the PAN is not stored, processed or transmitted by a York University merchant or service provider then PCI DSS requirements do not apply.

24. All cardholder data (CHD) is in scope for PCI DSS compliance validation if it is stored, processed or transmitted when the PAN is present in the cardholder data environment. CHD elements are formally defined to include the:

• primary account number (PAN)
• cardholder name
• expiration date
• service code

25. Sensitive authentication data should never be stored; its elements are:

• full magnetic stripe data or equivalent on a chip,
• security code (CAV2, CVC2, CVV2, or CID)
• PINs / PIN blocks

26. CHD and sensitive authentication data must never be communicated by unsecure email.

27. Responsibilities and activities of the PCI DSS Steering Committee and its delegates (the PCI Team) are to:

a. Maintain, update and communicate the Payment Card Data Security Guideline and Procedures.

b. Conduct annual PCI DSS training.

c. Advise on prudent actions and best practices for achieving and maintaining PCI DSS compliance.

d. Arrange for required assessments and validation by a Qualified Security Adviser (QSA) and an Accredited Scanning Vendor (ASV).

e. Gather, review and approve SAQs as prepared in tandem with merchants.

f. Prepare, validate and submit annual AOC to acquirer(s).

28. Merchants are responsible for adhering to the following requirements with respect to their card acceptance arrangements:

a. Version: Handling of cardholder data (CHD) and all related processes are to be conducted in compliance with the current version of PCI DSS.

b. Authorization: All card acceptance arrangements shall be disclosed to the Treasurer and/or UIT Director for validation and authorization.

c. No hosting: University servers shall not be used for hosting.

d. Encryption: Networks may only be used for protected transacting, transmitting or storing of encrypted, masked or redacted CHD.

e. Access persons: Only authorized staffmembers shall be permitted to have access to CHD. Access shall be strictly controlled and tracked by a management-level access person. Each merchant’s controls are subject to periodic audit.

f. Transmission: All CHD received in communications to merchants for the purpose of handling card payments must be safeguarded and encrypted and/or masked during processing then redacted prior to storing.

g. Storage: University servers, computer hard drives, and paper archives are not to be used for storing unprotected CHD in any form (electronic, physical, or otherwise). CHD should not be archived and should be destroyed in a timely and secure manner.

h. Devices: Card acceptance devices and pinpads are to be protected at all times from theft or tampering. Device inventory and controls must be maintained up to date at all times.

29. Prior to a department, office or unit entering into an arrangement with a service provider that involves acceptance of payment cards, the service provider must initially, and annually thereafter, provide Attestation of Compliance and security certification as proof that:

a. The service provider is PCI DSS compliant as validated by a QSA.

b. The service provider software application and payment application is certified compliant with the Payment Application Data Security Standard (PA-DSS) for developers.

c. The service provider hardware, equipment and devices are certified compliant with the PIN Transaction Security (PTS) standards for manufacturers.

d. The service provider devices are EMV (chip and PIN) enabled, to protect from fraudulent card attempts and attacks.

30. Service provider and outsourcing arrangements are subject to validation to prove the University’s systems, infrastructure and networks are not being used for hosting, processing, transacting or transmitting cardholder data.

31. The University will not be responsible for any service provider security breaches and will be indemnified by the service provider for all costs and damages associated with security breaches caused as a result of negligence on the part of the service provider.

NON-COMPLIANT MERCHANTS

32. The procedure for addressing matters of non-compliance with PCI DSS at single merchant sites is as follows.

a. An identification of the reason for non-compliance will be assessed by UIT and Treasury or an external validator (QSA).

b. Notification by the Steering Committee that remediation is required will be communicated to the merchant.

c. The merchant will produce and communicate its plan including a series of steps to attain remediation to the Steering Committee for approval.

d. A mutually-agreed upon and reasonable timeline for remediation will be established by the merchant with UIT and Treasury.

e. Post remediation, an SAQ shall be completed by the merchant and subject to review will be approved for documenting that remediation has occurred.

33. Should remediation not be attained as per the timeline above, the Steering Committee will consider further actions and will issue a notification to outline the actions that must be taken by the merchant.

34. A non-compliant merchant may face increased costs due to fines levied by the payment card brands.

35. A persistently non-compliant merchant is subject to suspension or termination of card acceptance arrangements.

36. Active merchant status may be restored only when the unit has completed all applicable steps associated with these procedures.

UIT Information Security with Treasury shall assess the reported incident and coordinate actions and response in adherence to University policy and protocols.

d. The merchant must NOT resume normal business operations until notified by UIT or Treasury that it is safe to do so.

39. The procedures to be followed by UIT and Treasury upon discovery of a CHD breach or security incident are as follows:

a. Upon security incident notification, UIT and Treasury will assess a situation and immediately begin notifying necessary parties.

b. UIT and Treasury will determine whether circumstances surrounding a breach or security incident require notification of law enforcement.

c. If a security incident is confirmed, UIT and Treasury will coordinate the response in accordance with established University security and privacy incident guidelines and procedures, as well as the following PCI DSS requirements:

• Immediately contain the exposure of the security incident.
• Immediately notify the necessary institutional parties.
• Prepare the Incident Response Report and file with the merchant bank (acquirer) within 3 business days.
• Prepare a list of compromised accounts and file with the merchant bank (acquirer) within 10 business days.

40. If the security incident is contained to a single merchant, UIT and Treasury will assist that merchant with any required PCI DSS post-incident reporting.

41. The merchant if found to be responsible for a compromise may have its payment card handling privileges immediately revoked.

42. Costs associated with a security incident will be charged to the merchant, if found to be negligent or in violation of the University’s PCI DSS Guideline or Procedures at the time of the security incident.

43. UIT and Treasury shall include Breach and Incident Response Procedures in the annual training to ensure all merchants understand these responsibilities.

REVISION OF PROCEDURES

44. These Procedures will be reviewed by the Oversight Committee and revised or confirmed annually.
