Detailed explanation-1: -You can’t make a hub secure because it has no switching logic by definition. A switch, on it’s own, will make a best effort to figure out where to send information, but if it isn’t configured with exact information, an attacker may be able to fool it.
Detailed explanation-2: -What is a hub? A hub is a simple device that acts as a central point for connecting network cables. It receives data packets from one device and broadcasts them to all other devices connected to it. This means that every device on the network can see and access the data sent by any other device.
Detailed explanation-3: -No security: Since the hub broadcasts messages to every port, it is not possible to send any private frame. This allows other connected ports to access your data. Network Traffic is high: Hubs broadcast the frame/data to every connected device due to which the traffic is high.
