In part one of this series I talked about what was arguably the biggest cybersecurity story of last year, the retail breach of Target. In the so-called “year of the breach,” the Target incident loomed larger than the rest not only because of its number of victims, but because it happened at the very beginning of the year. For most consumers, the Target breach was the first indication that hackers are more powerful and ambitious than ever before, taking on big business and walking away unscathed. The U.S. Secret Service reports Target was one of 1,000 retail breaches detected in the last year. Despite all of this gloomy news, one undisputable fact remains: None of these breaches ever had to happen.
How the situation could have been avoided
One of the keys to preventing these types of intrusion lies with a well architected network that isolates high-value POS systems from other lower value systems like HVAC and inventory management systems. Any network that handles sensitive data needs to incorporate strong principles of segmentation. Many retailers fail to embrace segmentation and criminals have repeatedly taken advantage of this key weakness.
With strong network segmentation in place, hackers would have had a much harder time causing such a massive breach by simply stealing network credentials belonging to a third party HVAC contractor. Not only does network segmentation reduce retailer risk, but it’s also a requirement. If your network doesn’t have the proper segmentation outlined in the PCI Standards Council’s rulebook, it’s not compliant. Merchants out of compliance face fines and loss of credit card processing privileges – and those penalties are no walk in the park.
Let’s review the basics again: First, criminals breached a third-party HVAC company with ties to Target. Then, they used this third-party access to gain administrative privileges to Target’s network. Then they unleashed a sophisticated strain of POS malware that copied customer credit card data in the instant before it became encrypted. That stolen data then made its way into criminal hands.
Implementing solutions for your business
No business wants to become the next high profile breach victim. Target was able to weather the storm was due to its size. Most small to medium size enterprises would find it difficult to weather a breach.
Limit your risk by knowing what the hackers know: The first step to defending against cybercrime is to acknowledge that invincibility simply isn’t possible. If there’s one thing we’ve learned over the past 20 years, it’s that there’s no such thing as a 100 percent hack-proof business. One key move toward becoming as secure as possible is to understand your company’s security vulnerabilities. Hackers often conduct recon operations looking for the most vulnerable enterprises before they launch attacks. If you don’t have the resources on your IT staff to conduct a vulnerability assessment, consider partnering with a third party. Once you have a security baseline, you can make a plan to address vulnerabilities before hackers exploit them.. Then, make sure you’re PCI compliant, and if you’re not, pursue the solutions that will get you there.Fortunately, there are steps companies of all sizes can take to ensure that they don’t become the next victim of a hack. Here are some of them:

- Ensure network security: Security experts concur that if retailers had put more effort into securing their network and responding more quickly to security alarms, many breaches could have been avoided. But there’s no reason why you have to to be a victim too. So make an effort to keep your business connected safely. This starts by making sure the WiFi you offer in-store is not only convenient, but also safe for customers to use. It’s also very important to make sure that any information traveling over your network is secure. Fortunately, this is something EarthLink’s Multi-Protocol Label Switching (MPLS) solution is designed for.If you missed Part 1 of what happened to Target, and what the hackers did to steal the information from their terminals, you can get there here.
