Protect Your Point of Sale (POS) Environment from Cyber Attacks

Your point-of-sale (POS) system is the beating heart of your business. It’s where every sale rings up and where customer trust is secured with each transaction. But as essential as POS systems are, they also, to the surprise of many business owners, represent a prime target for cybercriminals. With high-profile data breaches making headlines across industries, it’s vital to ask yourself: “How secure is my POS environment, and what steps can I take to protect my business from a point-of-sale cyber-attack?” At Sunwest Bank, we are committed to helping you understand and navigate these challenges, ensuring that your business remains secure and customer data stays protected.

Understanding the Threat: What is a POS Cyber Attack?

POS cyber attacks occur when criminals exploit vulnerabilities in your POS system to gain unauthorized access to sensitive information, such as credit and debit card details. These attacks can take various forms, from malware designed to infiltrate POS software to exploiting outdated operating systems that have not been patched or updated. Once inside, attackers can siphon off sensitive data from your customer transactions, leading to significant financial losses and reputational damage. Understanding the nature of these attacks is the first step in building a robust defense that will protect POS systems in your business.

Common Types of POS Malware

POS malware is designed to infiltrate your point-of-sale system and help criminals commit credit card fraud with stolen card data. Some common types include:

• RAM Scrapers: These malware variants extract data directly from the memory of a POS operating system during the transaction process, capturing customer payment information before it is encrypted.
• Keyloggers: By recording keystrokes, keyloggers can capture usernames, passwords, and other sensitive information as they enter the system.
• Backdoor Malware: This type of malware creates a hidden entry point into your POS system, allowing attackers to access your network remotely and extract data without detection.

Why POS Security Matters More Than Ever

Data breaches originating from a POS terminal are a growing concern for businesses of all sizes. Headlines about major attacks serve as a stark reminder of the potential consequences. Compromised POS systems can lead to:

• Large-scale business and customer data breaches: Customer/employee names, credit card data, and even personal information can be stolen, causing substantial financial loss and reputational damage for all involved.
• Financial loss: Fraudulent charges on stolen credit card information can significantly affect profits.
• Disrupted operations: A POS system under attack can grind your operations to a halt, leading to lost sales and frustrated customers.

The Hidden Vulnerabilities in POS Systems

Many businesses view their POS systems as simple devices, unaware that these terminals are full-fledged computers that store information and require regular maintenance and updates. Unlike other business systems, POS terminals are often replaced infrequently, with some remaining in service for over a decade. This longevity can result in outdated operating systems and software, leaving them vulnerable to modern cyber threats. This is why protecting POS systems has become more critical than ever.

At Sunwest Bank, we emphasize the importance of viewing your POS systems as critical components of your business infrastructure. Just as you wouldn’t neglect the security of your main business network, the same level of attention must be applied to your point-of-sale environment. Regular updates, patches, and a proactive approach to cybersecurity are essential in minimizing the risk of a POS attack.

Securing Your POS Environment: Best Practices

Protecting your POS environment requires a multi-layered approach, combining technology, policy, and vigilant monitoring. Here’s how you can help you safeguard your systems:

1. Keep POS Terminals Up-to-Date

As with mobile devices, digital copiers, and other digital devices used for business, ensure that your POS terminals and operating systems are regularly updated and patched. If possible, antivirus software should also be installed. This reduces the risk of vulnerabilities that sophisticated malware attacks can exploit. Sunwest Bank provides resources to help you stay on top of these critical updates, ensuring your systems are protected against the latest threats.

2. Manage Remote Access Securely

Secure remote access is crucial whether you manage your point-of-sale systems in-house or outsource them. Third-party companies often use remote access tools for technical support, which can become a weak point if not appropriately handled. Insist on solid and unique credentials and consider implementing two-factor authentication (2FA) for accessing payment processing networks, even if Virtual Private Networking (VPN) is used. These measures help to mitigate keylogger and credential dumping attacks, providing an additional layer of security.

3. Encrypt Data in Transit

Data encryption is a cornerstone of point-of-sale security. By setting up Secure Sockets Layer (SSL) certificates, you can ensure that credit and debit card data is encrypted as it moves across networks. This encryption prevents attackers from quickly intercepting and reading the data, making it significantly harder for cybercriminals to steal money or access stolen data.

4. Actively Monitor for Malicious Activity

Cyber threats can often go unnoticed until significant damage has been done. That’s why actively monitoring your systems for signs of malicious activity is essential. This could include unusual outbound file transfers, unexpected changes in system behavior, or unauthorized access attempts. Antivirus software can help detect unusual behavior, but manual checks must be included in regular security measures.

5. Segregate Your POS Network

To prevent POS malware from spreading across your entire business network, it’s critical to segregate your POS system from other networks and databases. This isolation limits the potential impact of a breach, ensuring that the damage is contained even if one part of your system is compromised.
