Abstract: A system and method of securing a network including a plurality of computing systems connected via a network. The computing systems each include at least a processor, a memory, a user interface, and a communications interface. The memory includes a computing device-executable instructions (software program) so that, when executed by the processor, the processor: detects an attack event and sends a message comprising the attack event to the other of the plurality of computing systems via the network. Each of the other of the plurality of computing systems receive the message and perform a different response of a plurality of responses to the attack event.
