Abstract

Attacks on a network device, e.g. an IoT device, are detected by analyzing network traffic and subsequently quarantining or blocking the network device on the network to prevent lateral movement of malware. The techniques described herein relate to developing a baseline of network device activity corresponding with a network device during a learning period and comparing the baseline of network device activity with new network activity by the network device in order to identify potentially unusual network device activity by the network device. If unusual network activity is found, remedial actions such as quarantining the network device or restricting some access to a network may be initiated.
