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

Claim 0:
1. 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 first memory circuit; and
a processor circuit coupled to the first memory circuit and to the network interface circuit, the processor circuit configured to, using a configuration bit image stored in the first memory circuit, for a partial implementation of a network communication protocol, 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, and the processor circuit further configured to monitor data packets transferred between the network interface circuit and the host computing system or transferred between a data network and the network interface circuit and to detect a malware data packet from a data network or from the host computing system; and
in response to a detection of the malware data packet, using the processor circuit, 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.
