POS Protection: Five Ways to Keep Your Point of Sale System Safe

There are several options for retailers to enhance their POS security. At Comodo, we believe that implementing a strong POS protection program begins with knowing what it is. Attacks on Point of Sale terminals are sophisticated in nature and, therefore, it needs a focused POS security plan. There have been many data breaches caused by malware that attacks the point-of-sale system and many business owners have decided that they need to focus more on protection from these attacks Cybercriminals employ both hardware and software to steal business data and payment card information from payment networks, so it's important to understand the nature of POS malware and ways to prevent them from infecting a point of sale system.

How to Secure Point of Sale System from POS malware

POS protection is a weird area for most businesses and security companies because there isn’t a perfect solution that will stop all problems. However, there are some best practices and a POS protection tool that can help. These can include:

1. Maintain Point of Purchase (POP) software

The idea of protecting your valuable point of purchase data starts with the step of adopting an effective point of purchase software that benefits your requirements.

2. Install firewalls/antivirus

POS protection tools do not work in isolation. They work best in harmony with traditional preventive tools like antivirus and firewalls. Make sure you keep them switched on and updated all the time.

3. Create passwords and change them frequently

Keeping passwords that can easily be guessed or breached is like securing a house with a fragile glass lock. No matter how sophisticated your security software are, a data breach is very likely to be successful if you have weak passwords.

4. Don’t allow internet surfing from the terminal or POP station

POP devices are meant for processing card information, handling inventory data or even CRM requests. Use them exclusively for these purposes instead of opening them to vulnerabilities from social media and internet at large.

5. Disable remote access

Keeping POP devices safe requires limiting unnecessary access to the system, including remote access. By allowing access to the device from a remote location, you are only going to expand the threat landscape to unknown territories.

Updates to the point-of-sale system can include POS security patches. Make sure these are installed promptly so that your system isn’t vulnerable to attack. They can be easy to download and deploy, especially if you have an IT department.

A POS protection tool, such as ours, can also help. Traditional antivirus software can’t detect point of sale malware, but ours works differently. It is designed primarily to thwart attacks on these and other systems, such as ATMs.

You can also consider creating better passwords and require that they are changed every few months. Most company owners tend to use the default password on the Point of Purchase system instead of thinking up new and more difficult ones. These default passwords are posted everywhere online, making it easier for the attacker.

It’s also good practice to use a separate network for the point-of-sale system and not use the Internet on the point of purchase network. Contact us today if you’d like more information.
