What Are The Main Vulnerabilities Of POS Systems?

When we talk about Point of sale Software devices, we usually mean payment systems in shops that allow us to pay for services or goods using a credit card. POS devices have come a long way from the cash registers of 1883 to today's state-of-the-art terminals that process cards, store customer orders, manage inventory and connect to different systems on the same network. Unfortunately, new threats and vulnerabilities have always gone hand in hand with new features.

In December 2013, a hacker gained access to Target's POS system and was able to steal more than 70 million credit card numbers from customers. This major problem led to the loss of jobs and reputation for the company, as it was later discovered that the attack could have been prevented. Had they used a quality anti-malware system, the hacker's code would have been ineffective. Finding an anti-malware solution is easy, especially nowadays when everyone has access to review sites.

 What is malware and how does it work?

Understanding how malware works and how destructive it can be can be very difficult for someone who is not a technical expert. Malware is software designed to infiltrate computer systems and networks and disrupt or interfere with their normal functioning. Malicious software is usually introduced illegally into servers and computers in the form of software, scripts, active content or executable code.

Malware can therefore cause serious collateral damage to vulnerable POS systems. This may include access to customer personal data, bank accounts, card associations, insurance companies, etc. But when it comes to POS systems, the main objective of hackers is to steal credit card data. Once the hackers have this information, they create virtual credit cards and use them to buy goods or transfer money.

What are the most common mistakes people make when managing customer data?

Small business owners make a lot of mistakes in protecting their customers' user data. For example, keeping it in the same place as encrypted data is a very common mistake. This makes it easy for hackers to get all the information they need with a swipe of a card. A simple solution is to keep encrypted data separate from user data.

 

Another mistake is to use the corporate network to send security and system updates to all billing software for small businesses devices. This is a common practice that puts many businesses at risk. When the corporate network is not protected by a professional security setup, it is very easy for hackers to gain access to computers, networks and POS systems. A good solution for small businesses is to choose a multi-factor authentication system and never use a POS system on a public Wi-Fi network.

Is using an old operating system a security threat?

The short answer is yes. Older operating systems are vulnerable mainly because security support has expired once newer versions are released. In other words, when a new system is released, companies stop upgrading the old system. Sometimes companies release updates to older systems when they discover vulnerabilities that can be exploited. For example, critical

It is therefore important to ensure that your sensitive data is protected with the latest security patches.

Why is it dangerous to use default passwords?

Many people put off changing their manufacturer-supplied passwords because they may think they are as secure as other passwords. After all, they are just a bunch of random letters and numbers that are impossible for anyone to guess. The truth is, however, that a hacker can gain access to a manufacturer's list of passwords and easily gain access to any POS system that still uses them. Once the system is in place, it is best to change the passwords. It may be a good idea to use password encryption software to protect sensitive data.

What is phishing and how does it affect POS systems?

Phishing is a hacking technique where emails are used to trick people into revealing sensitive information such as credit card numbers, passwords, etc. It can also be used by fraudsters to gain access to POS system. To avoid such hacking, business managers should train all employees not to open suspicious emails.

It is important to remember that when hackers gain access to the POS network, a large amount of sensitive data can be compromised. It is therefore vital that business leaders hire qualified security experts and ensure that their systems are up to date and secure.
