And other malware? And DDoS attacks? Manufacturers are waking up to issues about which they need to be on high alert.
T
he nexus of cyber and physical security threats is the stuff of nightmares, and while manufacturers are waking up to it as a real- ity, experts worry that the
awakening is happening too slowly. A handful of incidents in recent years in which hackers have been able to remote- ly control machinery have underlined the risk, but experts say it may take a more seismic shock to the industry to spur the necessary action in cyber defense. That relative inertia, coupled with the
growing complexity of manufacturer’s digital assets, will pose a stiff test for
manufacturers trying to defend their en- terprises in the near term. “The risk is getting bigger and big- ger because of the tighter digital in- tegration,” said Ralph Langner. The co-founder and managing principal of a consulting and software fi rm that bears his name was among the fi rst to decode the infamous computer worm called Stuxnet. “Here’s the problem: We are creating so [many] more cyber-physical inter- dependencies and at the same time we don’t spend enough eff ort to actually understand those cyber-physical inter- dependencies.”
