CYBER DEFENSE
There is a clear and present danger: A rise in recent
cyberattacks on manufacturing have made it the second most hacked sector after healthcare, according to re- search from IBM. The automotive industry accounted for 30 percent of
attacks aimed at manufacturing in 2015, the most of any category within manufacturing, according to IBM, which did not name any of the automotive companies hacked. Chemical manufacturers were the second most targeted category of manufacturers, the report said. For starters, Langner and others predict ransomware—
malware that encrypts a computer user’s data until hackers are paid off, usually via crypto-currency—will soon become a force to be reckoned with in manufacturing. But it is not all doom and gloom. Practitioners say the baseline of cyber defense in the in-
dustry is rising, the cyber insurance market for manufacturers is blooming, and some standards initiatives are bearing fruit.
Playing catch-up Two features of U.S. manufacturing have made it inher- ently challenging for the sector to tackle cybersecurity compared with some other sectors, according to analysts. One is the fact that manufacturing is not regulated in
its cybersecurity practices in the way, for example, that the electric utility industry is. Electric utilities face fines if they do not comply with mandatory cybersecurity standards set by the North American Electric Reliability Corp.’s Criti- cal Infrastructure Protection plan. There is no such punishment hanging over manufactur- ers, which some argue has led to insufficient cyber invest- ments in the sector.
“One thing I learned a long time ago in this business… is people don’t spend money unless they have to,” said Mark Weatherford, senior vice president of vArmour, a firm that specializes in data center and cloud security. “Unless there’s a compliance requirement, my experi-
ence is that people are not going to spend money on se- curity just because it may be the right thing to do,” added Weatherford, a former cybersecurity official at the Depart- ment of Homeland Security. Absent regulation, security professionals have tried to build a more robust set of voluntary standards to which manufacturers and others can adhere. “Within the standards realm, there’s growing recogni-
tion that there is an intersection between functional safety and cybersecurity,” said Brian Wisniewski, engineering security manager at Rockwell Automation.
