      Cybersecurity for Retail

      Cybersecurity is an ongoing concern for retail organizations. The retail sector is also highly regulated by compliance frameworks such as PCI-DSS. In 2021, cyberattacks on retail and e-commerce organizations surged by 264%, according to a SonicWall report. One in every five ransomware attacks targeted a retail company.

      Limited Resources Leave Retail Organizations At Risk

      While many retail organizations turn to traditional Security Information and Event Management (SIEM) platforms to detect cybersecurity threats, most organizations have limited resources to engineer the product to work effectively.

      Traditional SIEMs require regular optimization to defend against the latest cyberattacks. In large corporations, a 24/7 Security Operations Center (SOC) staffed by a group of specialized IT security analysts sift through alerts, determine the severity of each, take action on the most important ones, and feed and maintain the system on an ongoing basis. 

      Common Security Risks and Challenges for Retail Companies

      Take a look at some of the most common risks and hurdles for the retail sector.

      Value of Consumer Data Retail organizations experience a high volume of target attacks because of the value of credit card and consumer data. On average, the cost of stolen credit information is over $17 and $171 for a physical, cloned credit card, according to a Comparitech study. 
      E-Commerce Exposure E-commerce encourages retailers to adopt feature-rich and ultra user-friendly websites, sometimes lacking security measures such as multi-factor authentication that create more steps for end users.
      New Technology New retail technology such as updated point-of-sale (POS) terminals, internet of things (IoT) devices and cloud-based storage creates more data, and therefore a greater attack surface for attackers to infiltrate. 
      Credit card skimming attacks These attacks can be either physical or virtual. In digital skimming attacks, threat actors take advantage of vulnerabilities in third-party JavaScript or misconfigured permissions in AWS to access source code. Then they inject malicious code into a website and steal credit card data. Magecart is one example of this type of attack and specifically targets e-commerce platforms such as Magento.
      PoS malware In this type of attack, an adversary uses a tactic called RAM scraping, which targets random-access memory (RAM) to steal unencrypted credit card information in a compromised PoS device.
      Supply chain attacks A retail organization typically works with many different third-party vendors to support its operations. Each of these vendors introduce risk and opportunity for threat actors to launch an attack. In the 2013 Target breach, for example, threat actors gained access through network credentials stolen from an HVAC company.

      Cybersecurity Best Practices for Retail Companies

      There are some best practices that IT teams in retail can follow, even with limited budgets and staff.

      • Prioritize end user training

        Prioritize End User Training

        IT and security teams should know about ransomware warning signs, but so should end users. Failure to train and educate users often points to a broader issue — a lack of security. That, combined with the fact that human error is the starting point for many cyberattacks, means that organizations should make training more of a priority. 

        At a minimum, IT and security teams should inform staff about how to spot a phishing email. More formal security awareness training is even better, but an informal chat about what a phishing email can look like and what to do is a good first step.

      • Deploy Sysmon

        Deploy Sysmon

        When it comes to preventing ransomware, it’s important to have visibility into an environment. Endpoint detection and response (EDR) tools can achieve that, but they can also be prohibitively expensive for retail establishments with limited budgets. System Monitor (Sysmon for short) is a free Microsoft utility that small IT teams can use to get visibility into their environments. Sysmon is part of the Sysinternals software package and provides a higher level of event monitoring than the standard Windows logs. It records events such as network connections, process creations, file hashes, and changes to the Windows Registry. 

        IT leaders without the budget for an EDR solution should deploy Sysmon for enhanced logging that can provide a wealth of data about endpoints. Since Sysmon is free, it does require more care and feeding than a plug-and-play paid tool. IT admins need to deploy updates as they are released and make configuration changes as necessary, but those tasks generally fall under the umbrella of standard patch management. It’s relatively easy to install and configure Sysmon in a few steps.



      • Implement Threat Detection and Response

        Implement Threat Detection and Response

        Using Sysmon and a centralized log management tool will provide some visibility into an environment and help with alerting, but small IT and security teams need to know how to respond to those alerts. A threat detection and response solution alerts IT and security teams on suspicious behavior that is indicative of a ransomware attack.
