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.
