Background on PCI & Credit Card Security
For many years, both restaurant owners and their diners have been enjoying the convenience of accepting and using credit and debit cards. However, given the skyrocketing cost and frequency of fraud on credit cards, well known card brands (Visa, MasterCard, American Express, Discover and JCB) have taken preventive measures to safeguard their stakeholders.
After IBM invented the mag stripe on credit cards in in 1968, it became the industry standard. Given that the track data on the mag stripe can easily be read and duplicated, the card brands, the Payment Card Industry Security Standards Council built a set of standards for securing cardholder data, and it begins with the directive: ‘Don’t store track data.’
PCI Standards
The PCI Security Standards Council had a three-pronged approach to protecting consumers, banks and merchants/restaurateurs:
- PCI DSS (Payment Card Industry Data Security Standard) ‐ covers all entities that store, process, or transmit cardholder data: Merchants, restaurateurs, service providers, processors, etc.
Deadline for Compliance: January 2007 (deadlines are long passed)
What it Means – Restaurant owners, regardless of their establishments’ size, must all complete and submit a PCI Self-Assessment Questionnaire to their Acquiring Bank yearly.
- Payment Application Data Security Standard or PA-DSS ‐ involves all applications used to store, process, or transmit cardholder data as part of authorization or settlement. (Point of Sale (POS) application developers)
Deadlines for Compliance:
Oct. 1, 2008 ‐ Only the software that is compliant with the new payment application security standards must be used by agents, merchants and payment processors.
Oct. 1, 2009 ‐ Terminate any noncompliant payment applications that merchants might still be using in their environments will be required.
July 1, 2010 ‐ Mandatory use of only the payment applications that support the new standards.
What this Means – After these deadlines, merchants/restaurateurs that are still running a non-PA DSS-validated application, they automatically fail the PCI assessment and may lose their ability to accept credit cards.
- Pin Entry Devices (PED) Standard – covers all PEDs and it aims to ensure that the cardholder’s PIN, and any sensitive information such as resident keys, are protected consistently at a PIN acceptance device.
Deadline for Compliance:
Jan. 1, 2004 ‐ Newly purchased Point of Sale (POS) PIN Entry Devices must have passed testing and approved by Visa from one of its recognized laboratories.
July 1, 2010 ‐ Mandates that all deployed Point of Sale (POS) PEDs must have passed testing by a PCI recognized laboratory and been approved by the PCI SSC.
Which Means ‐ Merchants/restaurateurs have two years to replace older, un-approved PEDs.
The Do’s With Payment Card Industry (PCI)
- Make routine vulnerability scanning of your systems.
- Do security awareness training for all of your staff.
- Do audits of system access.
- Monitoring of system activity logs.
- Access privileges should be removed for separated employees.
- Install software patches for your system.
- Be responsible when it comes to any threats, device an incident response plan.
PCI Don’ts
- Whole credit card numbers should not be stored or archived.
- Transmitting credit card data unencrypted should not be practiced.
- With Payment Card Industry, it’s not simply about proving you are compliant with the standards – it’s about protecting your business and your customers.
What Restaurateurs Get From PCI
Given consumers’ expectation of ever-present acceptance of using credit and debit cards, merchants’/restaurateurs’ validation that they are giving protection to their customers’ personal data is good for business:
Reputation / Image
In a competitive business – a restaurant owner does not want to be named in the media as the place were a card data was breached.
Protects Ability to Accept Credit / Debit Card Payments - neglecting the rules and/or a breach can endanger a restaurateur’s ability to accept credit/debit payments. There are several cases that 80% to 90% of transactions are through credit/debit payments. Losing the ability to accept credit cards means reduced traffic/customers.
The Effects of State Privacy Laws
A breach that discloses personal credit card information in one of the 40+ States with privacy laws may experience double impact on the side of the restaurateur. Being off-side with the Payment Card Industry can result in fines and lawsuit costs. Being off-side with State Privacy Laws is a crime punishable by confinement with possibly more serious consequences.
Compliance / Security Strategy
- Make sure you are using a PA‐DSS or PABP validated POS system
- Ensure you are using an approved PED
- Arrange for regular security awareness training for your staff, especially your supervisors
- Conducting a background check on all employees with administrative access to your system is a must
- Have a ‘Confidentiality Agreement’ contract with your staff
- When it comes to your PCI Self Assessment Questionnaire (SAQ), carefully and accurately complete the form and when you’re not sure with your answers, just ask
- If you notice gaps in the PCI compliance, develop a realistic plan to straighten it out
- Be matured in sustaining compliance
- Accessing controls
- Dual factor for system and device management
- Strong passwords and secure password storage
- Regularly monitor system activities for potential attacks as well as record evidences
- Control wireless access points
- Maintain secure configuration
- Section each network
- Maintain an Incident Response Plan and Test It
- Test and audit the cardholder environment like your business depended on it
It can be a daunting task the first time but when everything else is in place, ongoing PCI compliance is not an expensive undertaking. Besides, it’s good for you business to practice protecting the sensitive information that your customers trust upon you.
