Claim 19:
20. A method for detection of a malware data packet, the method comprising:
using a processor circuit configured to, using a configuration bit image for a partial implementation of a network communication protocol, to appear as a communication circuit or a communication device to a network interface circuit and be nonaddressable by both a data network and a host computing system, monitoring a plurality of data packets transferred between the network interface circuit and the host computing system or transferred between the data network and the network interface circuit, for detection of the malware data packet; 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; and
in response to detection of a change in an operating system stored in the host memory, using the processor circuit, halting the host processor and rewriting the operating system in the host memory.
