Assignee: nan
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 10:
11. An apparatus comprising:
a network interface circuit coupled to one or more communication lines for communication with a host computing system and with a data network;
a memory circuit configured to store a network configuration bit image; and
a logic element coupled to the memory circuit and to the network interface circuit, the configurable logic element configured using the network configuration bit image to have a partial implementation of a network communication protocol to appear as a communication circuit or a communication device to the network interface circuit and be nonaddressable by both the data network and the host computing system, the partial implementation of a communication protocol including only a physical layer of the communication protocol or only the physical layer and a data link layer of the communication protocol, and the logic element configured to monitor data packets transferred to or from the host computing system and to detect a malware data packet from the data network or from the host computing system; and
in response to a detection of the malware data packet, using the logic element, performing at least one action selected from a group consisting of: halting the host computing system; discarding the malware data packet; monitoring an operation implemented using the malware data packet; monitoring a host memory of the host computing system; monitoring a host operating system; halting a host processor; restoring the host operating system; and combinations thereof.
