The data breaches the majority of companies suffered from in the past years came from unsecured wireless devices like printers, scanners, mobile phones or laptops connected to their Wi-Fi network since cyber-attacks aim at these devices as the weakest points to get 'way in' to a business network.

In order to counter network infiltration, companies should make sure that the wireless devices they use pass at least vulnerability tests for WPA2 or WPA3. What’s more, it’s highly suggested to employ Common Criteria for Information Technology Security Evaluation (CC) to provide extra protection to these wireless devices.

CC refers to the Evaluation Assurance Level (EAL), which has seven levels graded from EAL1 to EAL7. Financial services generally use EAL6 augmented (or EAL6+) security compliance in their payment systems to justify the additional costs spent when handling high value protected assets that are transmitted in high risk situations.
