Do you use a credit or debit card online? I guess the answer is yes. There are many internet stores, hotels, car rentals, air lines and other companies that offer to make a purchase or pay for services online. It is simple and convenient! But how do they protect your sensitive financial data? One of the measures is PCI DSS, or the Payment Card Industry Data Security Standard. It was created to help organizations that process card payments prevent hacking, fraudulent charges and other breaches of security. However, some people say that PCI DSS does not ensure that card information remains safe.
The Payment Card Industry (PCI) Data Security Standard (DSS) is a set of comprehensive technical and operational requirements for making online transactions as safe as possible. The main principles of PCI standard are to build and maintain a secure network, protect cardholder data, maintain a vulnerability management program, implement strong access control measures, regularly monitor and test networks and maintain an information security policy.
According to these principles, organizations that process card payments need to install and maintain a firewall configuration, use and regularly update anti-virus software, encrypt transmission of cardholder data across public networks, restrict physical access to cardholder data, regularly test security systems and processes, etc.
The security standards are managed by PCI SSC (Security Standard Council). It regularly updates the PCI DSS by including new or modified requirements necessary to prevent breaches of security.
Before PCI DSS was created, card brands offered five different programs: Visa Card Information Security Program, MasterCard Site Data Protection, American Express Data Security Operating Policy, Discover Information and Compliance, and the JCB Data Security Program. They certified that merchants that accept their plastics meet minimum levels of security to protect consumer cardholder data.
It was not easy for a merchant to comply with the rules of each brand because the requirements for security management, procedures, policies and software design could vary. So in 2004 American Express, Discover Financial Services, JCB, MasterCard and Visa aligned their individual programs and released a worldwide standard – the PCI DSS.
The PCI DSS applies to all merchants that store, process or transmit cardholder data. Plus, it also includes guidance for software developers and manufacturers of devices used for card transactions. So if a company is dealing with storing consumer financial data, it must be PCI DSS compliant. Non-compliant companies can lose the ability to process card payments – that is a death sentence for commerce.
The merchants must validate their compliance every year. The PCI assessments can be performed by Qualified Security Assessors (QSA) – companies that have been certified by the PCI SSC. A directory of QSAs is published on the Security Standard Council website.
Small companies may use a Self-Assessment Questionnaire (SAQ). Depending on the requirements of the card brands in the merchant’s state, the questionnaire may need to be validated by a QSA.
As you see, PCI DSS has the best intentions to protect consumer data. However, some IT security professionals believe that it provides just a basic security layer. PCI DSS barely addresses the newest and upcoming threats, so it might not be enough to prevent the loss of financial data.
Some companies can be PCI DSS compliant and have security breaches! For example, in 2008 Heartland Payment Processing Systems, one of the largest payment service providers, reported a loss of credit card data of over 100,000 clients. Security breaches also occurred with Okemo Mountain Resort and the Hannaford Brothers – PCI compliant companies.
That’s why you need to be careful. Of course, PCI DSS is an excellent tool to make all merchants pay more attention to IT security. Without it, our sensitive financial data would be much more vulnerable. However, it is just the minimum standard, so it makes sense to take additional measures to prevent fraud.
