1. A method of obfuscating physical computers on a computer network from hackers, the method comprising: capturing packets on a computer network of physical computers; monitoring the captured packets to ascertain a schedule of a plurality of connection activations and deactivations of the physical computers on the network; surveying a logical topology of the computer network; instantiating and initializing a plurality of software-based host emulators, each host emulator configured to respond to an Internet control message protocol (ICMP) echo request packet; obtaining an Internet protocol (IP) address for each host emulator based on the surveyed topology; and connecting the host emulators to the base computer network over time based on the ascertained schedule and a random number generator, the connecting substantially interleaving the connecting of the host emulators with the plurality of connection activations of the physical computers.
