Modern industrial viruses, which spread via flash drives and other means, can permit remote administration to allow an attacker to maximize damage. Any system which becomes infected is likely to attempt to cali Home to notify an attacker that the infected facility is available to be destroyed.

This is the new method of warfare. To help circumvent this threat, keep all critical processes which can cause destruction of hardware wired to analog gauges and Controls as a backup. Modern industrial viruses keep the PLC readouts normal as the virus destroys in secret. Analog gauges and Controls capable of overriding the PLC should be essential safety eguipment.
