A method for preventing network attacks on baseboard management controllers. The method includes receiving, by the network controller, a packet from a computer networking device on a computer network, where the packet is destined for a baseboard management controller (BMC); determining, by the network controller, whether the packet contains a tag identifying that the packet has been determined to be free of suspicious or malicious traffic; on condition that the packet has been determined to not contain the tag, sending the packet to a network inspection module, by the network controller, to be inspected for suspicious or malicious traffic; and on condition that the packet has been determined to contain the tag, sending the packet to the BMC by the network controller using a side band interface.

Preventing network attacks on baseboard management controllers

A networking device based on risk factors is provided. The device includes a first communication interface, connected to a first LAN and a second LAN respectively; a second communication interface, connected to a network; a control module, electrically coupled to the first communication interface and the second communication interface respectively, wherein a user terminal has a network communication with the control module via the network, and the control module calculates a risk factor with respect to the user terminal, and determine connecting the user terminal to either the first LAN or the second LAN according to the risk factor; particularly, the first LAN and the second LAN could be VLAN respectively.
