With the exponential growth of online shopping in recent years, ensuring payment Security on eCommerce stores and platforms has become crucial. As the eCommerce industry grows, so does the importance of adhering to standards that protect businesses and their customers. Pci Dss is one of the core frameworks to ensure payment card safety in the digital world. But what exactly is it, and why should online retailers care?
PCI DSS stands for Payment Card Industry Data Security Standard. Established by major credit card companies like Visa, MasterCard, and American Express, it is a set of requirements designed to ensure that any company that processes, stores, or transmits credit card information does so in a secure environment.
For businesses, being PCI DSS compliant is not just a recommendation; it is often a requirement. Not only does it help protect sensitive customer data, but it also shields businesses from potential financial penalties and legal consequences resulting from data breaches.
In an age where a single breach can devastate a company’s reputation, the importance of PCI DSS cannot be overstated. Knowing a retailer is PCI DSS compliant gives consumers the confidence to shop with peace of mind, knowing their payment information is safe.
Why is Payment Security Necessary for eCommerce Business?
eCommerce businesses deal with abundant sensitive information. Cybercriminals are eager to exploit sensitive data, from home addresses to payment details. Ensuring payment security is not about securing credit card details but creating an overall environment where customers feel their data is respected and protected.
Several layers contribute to this security:
Encryption
Encrypting data ensures that the information remains unintelligible to unauthorised parties even if intercepted.
Secure Socket Layer (SSL)
SSL certificates ensure secure data transfer, especially during transactions. Most shoppers now look for the padlock symbol in their browsers before purchasing.
Tokenisation
Instead of storing sensitive card details, systems can use tokens representing the card data without exposing the actual information.
Regular Security Audits
Ensuring an eCommerce platform is checked for vulnerabilities and keeping software up to date are pivotal to maintaining a secure environment.
Understanding PCI DSS Requirements
The PCI DSS is built around 12 fundamental requirements, broken into six broader categories. These requirements serve as a roadmap for businesses to safeguard customer payment data:
Build and Maintain a Secure Network and Systems
• Install and maintain a firewall configuration to protect cardholder data
• Change vendor-supplied defaults for system passwords and other security parameters
Protect Cardholder Data
• Protect stored cardholder data
• Encrypt transmission of cardholder data across open, public networks
Maintain a Vulnerability Management Programme
• Use and regularly update anti-virus software or programs
• Develop and maintain secure systems and applications
Implement Strong Access Control Measures
• Assign a unique ID to each person with computer access
•Restrict physical access to cardholder data
Regularly Monitor and Test Networks
• Track and monitor all access to network resources and cardholder data
• Regularly test security systems and processes
Maintain an Information Security Policy
• Maintain a policy that addresses information security for all personnel
It is essential to familiarise oneself with some key definitions to understand PCI DSS:
Cardholder Data (CHD)
This refers to any information printed, processed, transmitted, or stored in any form on a payment card. It encompasses the cardholder’s primary account number (PAN), cardholder name, expiry date, and service code.
Sensitive Authentication Data (SAD)
It is related to the information used to authenticate cardholders and confirm payment card transactions. It includes full magnetic stripe data, CAV2/CVC2/CVV2/CID, and PINs/PIN blocks. It is important to note that SAD should never be stored post-authorization.
Merchant
Any business entity that accepts payment cards bearing the logos of any of the five members of the Payment Card Industry Security Standards Council (PCI SSC) – American Express, Discover, JCB, MasterCard, and Visa – as payment for goods or services.
Service Provider
A business entity, excluding the payment brands, directly involved in processing, storing, or transmitting cardholder data on behalf of another entity.
Risks of Non-Compliance
Safeguarding customer payment data is not just a matter of ethical business practice. It also helps avoid substantial financial and reputational risks. Many eCommerce businesses underestimate the implications of non-compliance with PCI DSS, but doing so can lead to severe consequences.
Not being able to comply with Pci Dss Compliance exposes businesses to potential fines and penalties:
Banks impose fines
The banks that process payment card transactions can fine for non-compliance. These fines range from a few thousand pounds and can escalate to tens or even hundreds of thousands of pounds for repeated violations or in case of a data breach.
Compensation costs
If a business suffers a data breach due to non-compliance, it must compensate affected customers. These compensations cover fraudulent transactions and credit monitoring services.
Forensic investigations
Post a breach, the business might need to conduct a forensic examination to determine the cause and extent of the breach. Such investigations come at a substantial cost.
Loss of card processing privileges
In extreme cases of non-compliance, the license to process card transactions can be revoked. For an eCommerce business, this spells disaster, significantly hampering sales and operations.
Loss of customer trust
Customers entrust their payment data to eCommerce businesses, expecting it to be kept safe. A breach shatters this trust, making it challenging to rebuild. Many customers might choose never to shop at that eCommerce store again.
Bad publicity
Data breaches, especially payment information-related, attract media attention. Negative press can tarnish a brand image, leading to declining sales and profitability.
Drop in shareholder value
For a publicly traded company, news of non-compliance or a related data breach can negatively impact their stock price, affecting shareholder value.
Steps to Ensure Compliance for eCommerce Stores
Achieving and maintaining PCI DSS compliance requires proactive action. Let us explore the crucial steps eCommerce stores should take:
Securing Cardholder Data: Storage, Transmission, and Encryption
Securing cardholder data remains the key aspect of PCI DSS compliance. Here is how to ensure that cardholder data is secure:
Limit data storage
Only store cardholder data if essential. Regularly audit and delete unnecessary stored data.
Use robust encryption
When transmitting cardholder data across open, public networks, use strong cryptography and security protocols, such as SSL/TLS or IPSEC, to safeguard sensitive cardholder data during transmission.
Protect stored data
Implement encryption, truncation, tokenisation, or masking to protect stored cardholder data. Avoid storing sensitive authentication data after transaction authorisation.
Regularly Testing and Monitoring Security Systems
There needs to be more than a static approach to security. Continuous monitoring is the key:
Conduct vulnerability scans
Regularly scan the systems for vulnerabilities. Many third-party providers offer services that identify potential weak points in your network.
Perform penetration tests
Periodically test to see how well systems can fend off attacks. These tests simulate cyberattacks, helping identify areas of improvement.
Monitor access logs
Keep a keen eye on who accesses the systems. Suspicious activity can hint at potential security threats.
Implementing Strong Access Control Measures
Only some people within the business need access to cardholder data. It is important to restrict and monitor access:
Role-based access
Assign access to cardholder data based on job roles. Only provide access to employees who need it for their job functions.
Use unique IDs
Ensure each person with computer access has a unique ID. It helps in tracking and monitoring individual access.
Two-factor authentication
Implement two-factor authentication for added security, especially for remote access. It requires users to provide two separate forms of identification before gaining access.
