A poorly configured Wi-Fi network can give attackers access to dealership systems from the parking lot or another nearby public area. Using one shared network for customers, employees and sensitive business applications creates opportunities for malware infections, stolen credentials, network snooping, session hijacking and unauthorized access to customer, vendor and employee data.
Dealerships should separate Wi-Fi into distinct networks for guests, general operations and high-risk sales and finance activities. Each network should use strong encryption, unique passwords, current security software and appropriate access controls, with a VPN protecting traffic on shared connections. Real-time monitoring can also identify rogue access points, unencrypted activity and attempted intrusions before attackers move deeper into dealership systems.
