After having learned how to create a blacklist of SSIDs, today I’d like to share with you a useful opensource tool to prevent simultaneous connection to a wifi and a wired network.

From the security point of view it’s indeed important to prevent a device (laptop…) that is connected to the corporate network (trusted) to be able to connect simultaneously to a different untrusted network (for example to a wifi hotspot). This connection may allow the loss of reserved documents or the entry of viruses and malwares.

A colleague suggested me the use of Wired WiFi Switcher, that is able to automatically disable network cards, based on the preferred order you choose during the setup:

wifi-switcher

A good free and lightweight solution!
