Understanding Payment Security and Its Impact

Who Needs to Be Concerned about Payment Security? Everyone.


While you may have heard the news stories in recent years of data breaches at large retailers like Target and Macy’s, large retailers aren’t the only targets of credit card data breaches. Small businesses, while less lucrative for cybercriminals, can present easy pickings if the merchants accept credit cards and haven’t taken basic steps to secure their payments environment. Here’s what ISVs and their merchants of any size can do to reduce the risk of having thieves access their customers’ sensitive credit card data.


Payment Security Tips

Global Payments Integrated recommends a multi-pronged approach to payment security, combining EMV, encryption and tokenization to keep cardholder data safe. Here are a few ways for ISVs and their merchants to keep payments secure.

Limit Stored Data

With credit card payments accepted in-store and online, there are a number of opportunities for merchants to store personal payments data, physically and digitally. Credit card data is often maintained for customer convenience – for repeat and return purchases, for instance. However, stored data (sometimes referred to as “data at rest”) is vulnerable to hackers and malware. Businesses should aim to eliminate or limit storage of cardholder data. When storage is necessary, this data must be stored securely and according to the individual PCI compliance requirements.

Encrypt & Tokenize

The safest course of action to protect customer information is to move it out of the merchant environment altogether. Where does one move it? Payment vaults in the cloud are offered by a number of processors, permitting access to stored data when needed for a transaction. At first blush, this would not seem more secure, as data is in transit and, therefore, accessible. This method is rendered safe through the proper use of encryption and tokenization. The data is still accessible in transit, but is encoded and converted into digital tokens which cannot be deciphered without the decryption key.

Embrace EMV

EMV is a fraud-reducing technology that protects against losses from the use of counterfeit cards. The majority of credit cards now include the EMV smart chip, generating a new code for every transaction, making the card virtually impossible to falsify and re-use. The chip interacts with hardware devices and payment networks to ensure the card is authentic. In industries where card fraud is a concern, merchants should obtain the hardware and software necessary to accept the new payment standard.

Leverage Security Experts

Payments security is complex and changing constantly as new technologies emerge. Businesses should select a payment processor or partner who can help analyze systems, identify vulnerabilities and deploy solutions to prevent unauthorized access to customer information. Small businesses must now have their payment applications and terminals installed by Qualified Integrators and Resellers (QIRs). These security professionals are trained and certified to install and maintain PA-DSS validated payment applications.
