Cyberattacks are becoming an increasing risk to food production and safety, according to a new report from researchers at the University of Minnesota.
As well as illustrating the mounting cybersecurity risks facing the food industry, the report also provides industry-specific guidance to keep operations safe and secure.
The potential consequences of an attack on the industrial control systems used in the food industry include contaminated food that threatens public health, physical harm to workers, destroyed equipment, environmental damage, and massive financial losses for companies, the report says.
While cybersecurity is rarely recognised as a food safety issue, the systems companies use for processing and manufacturing food contain many vulnerabilities that experts believe will soon present a more appealing target for cyberattacks than industries that are more commonly affected by, and therefore better prepared for, such attacks.
“The food industry has not been a target of costly cyberattacks like financial, energy, and health care companies have,” said lead author Stephen Streng.
“However, as companies in those sectors learn to harden their defences, the attackers will begin looking for easier victims. This report can help food companies learn about what could be coming their way and how to begin protecting themselves.”
Researchers and manufacturers identified more than 200 industrial control system vulnerabilities in 2011, the report notes, with the number increasing each year through 2016, the end of the study period.
The vulnerabilities are present in a wide variety of components from different vendors, making them difficult for companies to avoid. Many systems were designed before cybersecurity was a concern and use outdated operating systems and hard-coded passwords that allow attackers easier access to the system.
In addition to vulnerabilities in the systems themselves, many other factors contribute to the heightened risk of cyberattacks. Companies often lack knowledge about how their industrial control systems and IT systems interact and lack awareness about cyber risks and threats.
Further, there is poor coordination and information-sharing among food system stakeholders. Meanwhile, the tools required to carry out a cyberattack are becoming more powerful and requiring less skill to use.
“The food industry has some characteristics that make it uniquely vulnerable to cyberattacks on its processing and manufacturing systems,” Streng said. “Luckily, there’s still time for companies to protect themselves.”
Moving forward, the report recommends that the food industry foster stronger communications between operations technology and IT staff, conduct risk assessments that include inventories of both industrial control and IT systems, involve staff with cybersecurity expertise in procuring and deploying new industrial control systems, and extend the existing culture of food safety and defence to include cybersecurity.
