With the rapid growth of POS transactions, security vulnerabilities are also growing. Multiple cyberattacks on the POS system occur every minute in restaurants and retail outlets. 

Point-of-sale malware has become one of the biggest sources of the stolen financial payment card information. You will be shocked to know about the mega-breach of 2013–2015 that compromised nearly 100 million payment cards in the US. The scenario is roughly the same as it has been up to this point. Even cybercriminals have sharpened their methods to pave the way for the deployment of POS malware.

As a result, the question should not be why they continue to occur. Rather, it should be about how to protect your POS system from the rising threats of a POS attack. Let’s look at the best POS cyber security practices and applications for your system.

What is POS Security?

From personal information to credit card information, every POS application contains a huge amount of customer data. Cybercriminals can use this information to steal money or commit identity fraud on a larger scale. 

So, preventing unauthorized users and hackers and creating a solid barrier against malware activities is a must for a POS system environment.

Here, POS cyber security comes into play. POS system security prevents hackers, in disguise as unauthorized users or malware functions, from accessing consumers’ personal data or electronic payment systems. 

Thus, it secures the POS back-end system and ensures a safe environment for making purchases and completing transactions. 

What Is the Process of POS Security?

Hackers are constantly on the lookout for potential weaknesses in firewalls or holes in the security features of POS systems that might allow them to launch social engineering attack methods. They sometimes use the old login credentials to access the cardholder’s data. 

Cybercriminals manipulate the victims into revealing confidential data. Under the guise of companies, the hackers send emails attached with malicious links to the recipients. Once the recipients click on the link to a bogus destination page or enter their login credentials, the malware gets deployed.

The malware spread through the organization’s POS system memory in no time. They are designed to steal information from the POS system and terminals. So, after getting deployed into a POS system, it allows the hacker to access the entire system or particularly targeted data terminals. 

Then, the hacker moves the data to another location to gain access to the company’s networks and systems. They fraudulently use credit card data or sell other personal information to third parties.

How POS cyber security applications helps in this matter?

The POS cyber security applications are designed to prevent data breaches and theft. Their advanced encryption process, code signing, efficiently prevents tampering, and the usage of chip readers makes it more difficult for the hackers to replicate card data, as the customer doesn’t swipe their credit or debit card while making the transaction.

This way, the POS system security application can prevent the deployment of such dangerous POS malware and all sorts of unauthorized practices.

What Is the Importance of POS Security?

A ransomware attack on the POS system and network could result in significant financial losses, legal issues, reputational damage, and a lengthy shutdown to correct the errors. You will end up losing all your goods due to shipment theft, and likewise, supply chain disruption will lead you to lose productivity.

Moreover, your POS system will be dealing with a lot of highly confidential data, like financial data, usernames, passwords, etc. If data breaches affect your consumers’ data and lead to major financial loss, you may have to compensate the affected customers. In addition to that, the cost to revive the system would not be affordable enough.

That’s why every organization must integrate POS cyber security with their POS system to secure their back-end system from malware, theft, or any fraudulent activities.

How to Secure Your POS?

Now the question is: how? Once the integration process is complete, your system won’t be safe enough until you follow these best practices for securing your POS system:

  • First and foremost, install a trustworthy POS cyber security solution to safeguard sensitive customer and internal data on the back-end system.
  • Next, train your employees about the security policies and potential risks of POS security by discussing previous incidents.
  • Also, educate the trainee, new hires, and even your customers about why they should not click on any unknown links or download email attachments.
  • Last but not least, keep your operating system, POS system, and POS security application up to date with the latest security patches.

Can a POS system be hacked?

After making all efforts, the hacker could gain access to your highly confidential customer data, even the encrypted information. Some of the world’s largest corporations have experienced cyber theft in their POS systems. DoorDash was hit by a data breach in 2019 that affected the data of 4.9 million customers, workers, and merchants, and even in 2022, it will impact the personal information of certain customers and drivers. 

So, keep an eye out for a weak point in a firewall and data mining activities via a phishing email or message.

What is a POS attack?

A POS attack is a fraudulent or malicious activity by POS malware that steals financial data stored in the POS system’s temporary memory. The hackers take advantage of the security vulnerabilities of POS systems and deploy malware to do such unethical activities.
