Whitepaper “Hidden Networks: Detecting Hidden Networks created with USB Devices”
Many companies and government agencies today have communications isolated networks or with data flow restricted through different networks.
These computers networks are created for particular situations, as these can be very special or have critical information such as, factory control system, highly-secured environments for processing of certain data, or networks complying with a safety standard. In recent Cyber-security history, it has been proven how a malicious software called Stuxnet infiltrated into an isolated network at a Nuclear Power Plant.
In light of this fact, it could be seen that having a computers network not connected through Ethernet cable or WiFi to other networks is not enough. Any type of external connection for computers may constitute a threat. This paper reflects the possibilities provided by the so-called Hidden Network and how these can be identified and focused on protection of these issues inside a corporate network.
