FIGHT-THROUGH NODES FOR SURVIVABLE COMPUTER NETWORK

A network node includes enhanced functionality to fight through cyber-attacks. A plurality of virtual machines run at the network node. The network node receives a plurality of transaction requests and distributes a copy of each of the transaction requests to the plurality of virtual machines over a plurality of time steps. Based on the first virtual machine having executed (n) transaction requests in the plurality of transaction requests, the node detects whether any of the virtual machines has been compromised. In response to detecting the plurality of virtual machines includes a compromised virtual machine, the network node isolates the compromised virtual machine. Furthermore, after isolating the compromised virtual machine, the network node may receive a subsequent transaction request and dispatch the subsequent transaction request to the compromised virtual machine. The compromised virtual machine may execute the subsequent transaction request.
