Trust is vital to any online transaction; people can share personal or financial information. For online merchants, securing payment systems is necessary for customer satisfaction and avoiding costly data breaches.
Our latest article outlines essential practices for securing an online store, protecting customer data, and adhering to PCI compliance guidelines. The security steps will help you maintain a secure online business and build lasting customer trust.
What is payment security?
Payment security refers to the set of practices and technologies that protect sensitive payment information during online transactions. Security practices include encryption, secure payment gateways, and tokenization, which replace sensitive data with non-sensitive equivalents.
With payment security, customer payment information is safe from cyber threats like hacking, phishing, and data breaches. Without proper protection, online stores put themselves and their customers at risk.
The consequences of inadequate security
A lack of proper payment security can have devastating effects. If your store is compromised, stolen credit card information, loss of customer trust, and even financial penalties can result.
Large-scale breaches often make headlines, reminding us that no online business is immune. When customers feel their payment data isn’t safe, they will likely take their business elsewhere. For an online merchant, the damage can go far beyond just lost sales—it can harm your brand and lead to years of rebuilding your reputation.
Essential practices for payment security
Businesses must follow several security practices to protect customer information and prevent fraud. The data protection steps below will help create a secure online transaction environment.
SSL/TLS encryption: Protecting data in transit
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are encryption protocols that safeguard sensitive data, such as payment information, as it moves between a customer’s browser and your website. Without encryption, cybercriminals could easily intercept and misuse sensitive data.
Most payment gateways use SSL/TLS encryption as standard practice, but as a merchant, ensuring your website implements it across all transactions is critical.
SSL certificates authenticate your website’s identity, creating a secure connection between the web server and the browser. Customers who see the padlock icon in their browser’s address bar are confident that their data is protected. Failing to use SSL/TLS encryption sends the wrong message to customers and puts their data at risk.
Strong authentication methods
Authentication is verifying a user’s identity before granting access to sensitive information. Implementing multi-factor authentication (MFA) is one of the most effective ways to secure payment systems.
With MFA, customers (or staff members) must verify their identity using multiple methods, such as a password and a verification code sent to a mobile device.
Additionally, requiring customers to use strong, unique passwords can enhance payment security.
Encourage password policies that require a combination of letters, numbers, and special characters to reduce the risk of credential theft. Although these steps might add extra effort to the user experience, they are essential security practices that protect your customers and business.
Regular security audits and vulnerability testing
Maintaining a secure online store requires more than setting up protective measures once and forgetting about them. Regular security audits are necessary to identify and fix weaknesses before criminals exploit them.
Vulnerability testing simulates real-world attacks on your systems, allowing you to uncover security gaps that may otherwise go unnoticed. Investing in third-party services specializing in vulnerability testing can help ensure your online store is always one step ahead of cyber threats.
Employee training and awareness
Employees are often the first line of defense in maintaining payment security. With proper training, they may avoid errors that allow hackers to compromise the most secure system.
Best practices for employee training:
- Conduct regular security awareness training to educate employees on the latest threats, such as phishing scams.
- Implement phishing simulations to test and improve employee responses to fake emails to steal sensitive information.
Achieving PCI compliance
The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards created to ensure that all businesses that accept, process, store, or transmit credit card information maintain a secure environment. Adhering to PCI standards helps protect cardholder data from theft and reduces the chances of a data breach.
PCI DSS outlines six primary objectives: building secure networks, protecting cardholder data, maintaining a vulnerability management program, and monitoring and testing networks. While PCI compliance might seem complex, running a safe online business is necessary.
The PCI compliance checklist
Merchants can follow a PCI compliance checklist to ensure they meet the requirements for securing payment information. The checklist includes several vital actions:
- Use firewalls: Establish a robust firewall to protect cardholder data from unauthorized access.
- Encrypt transmission of cardholder data: Use encryption when transmitting cardholder data over open public networks.
- Maintain secure systems and applications: Ensure systems are up-to-date with the latest security patches and address known vulnerabilities promptly.
- Restrict access to cardholder data: Limit access to sensitive data to only those employees who need it to perform their job duties.
Understanding PCI compliance levels
PCI compliance has four levels, depending on the volume of transactions your business processes annually. The levels determine the scope of the requirements you must follow.
| Level | Transaction volume (Annually) | Requirements |
|---|---|---|
| 1 | Over 6 million transactions | Annual internal audit, quarterly network scan |
| 2 | 1 to 6 million transactions | Annual self-assessment, quarterly scans |
| 3 | 20,000 to 1 million e-commerce transactions | Annual self-assessment |
| 4 | Fewer than 20,000 transactions | Annual self-assessment, potential quarterly scans |
Knowing your compliance level helps ensure your business meets the proper standards for data security.
Modern technologies for payment security
As technology evolves, new methods to secure payment transactions have emerged, offering more security to help businesses safeguard sensitive customer data.
Below are crucial technologies contributing to payment security.
- Blockchain
Blockchain technology offers a decentralized and transparent payment process. Instead of relying on a single server, blockchain transactions are recorded across multiple systems, making it difficult for hackers to manipulate data.
Benefits of blockchain for payment security
- Immutability: Once a transaction is on the blockchain, no one can alter or delete it.
- Transparency: Every transaction is visible to authorized participants, which makes it easier to track and audit.
While blockchain offers great potential, it is still an emerging technology, and businesses should weigh its benefits against its implementation challenges.
- Tokenization
Tokenization replaces sensitive payment information with a randomly generated string of characters called a token. Even if hackers access the data, they cannot use it to complete a transaction.
Advantages of tokenization
- Reduces the risk of data breaches.
- Simplifies PCI compliance by limiting the scope of protection
Many businesses use tokenization to handle payment card data, ensuring that sensitive information storage is encrypted.
- Biometric authentication
Biometric authentication uses a person’s unique biological characteristics, such as fingerprints or facial recognition, to verify their identity. It provides a higher level of security than traditional passwords.
Benefits of biometric authentication
- Since biometric data is unique to each individual, it’s harder for attackers to fake.
- Customers can authenticate payments quickly and easily using their biometric data.
However, biometric systems also have limitations, such as the need for specialized hardware and concerns about privacy.
Best practice for securing your payment
With the numerous processes a business must handle, the best way to protect your payments may be through integrating a dedicated payments platform to handle all your transactions.
A payment gateway acts as the bridge between a customer and the financial institution processing the payment. Selecting a secure payment gateway is one of the most important decisions you’ll make as an online merchant. Look for gateways prioritizing payment security through encryption, fraud detection, and tokenization.
Ensuring the payment gateway complies with PCI DSS standards is also essential. By selecting a trusted and secure payment gateway, you reduce the risk of fraud and give your customers peace of mind.
Staying updated on security regulations and threats
Here’s how to protect your business by staying updated:
