Patent ID: 11914758
Assignee: nan
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 15:
16. A system comprising:
a network interface circuit coupled through an interconnect or an interconnect switch for communication with a host computing system and with a data network;
a nonvolatile memory circuit configured to store a configuration bit image; and
a processor circuit coupled to the nonvolatile memory circuit and to the network interface circuit, the processor circuit configured to, using the configuration bit image 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, the processor circuit further configured to monitor data packets and to detect a malware data packet transferred between the network interface circuit and the host computing system or transferred between the data network and the network interface circuit; 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.
