Survey: Majority of Manufacturers Use Outdated Operating Systems
With the Internet of Things (IOT) comes possible improvements in efficiency, and also more vulnerabilities. Conversely, older systems can’t always defend against today’s digital attacks.
Most manufacturers used out-of-date operating systems, TrendMicro revealed in a survey of its customers. Among TrendMicro’s customers who attached onto their proprietary infrastructure, the company discovered that the majority work on Windows XP, which was rolled out in 2001 and is now not supported. There are some good reasons for businesses to use it: Windows XP is robust, not hard to use, and does not get in its own way as much as its successors. If companies do not want to go through the trouble overhauling their operating system and possibly retraining workers and clients, they could do worse than Windows XP. Additionally, newer operating systems have had less time to trickle-down through the industry, making it mathematically more likely that older systems will be in use.
Robert Hannigan of BlueVoyant highlights in a post for manufacturing.net that 2017 was a turning point for C-suite executives in manufacturing. This was when they saw that ransomware attacks like Wannacry and NotPetya strike businesses hard, even if manufacturers specifically were not affected. It takes a long time to turn the ship.
TrendMicro found that among the companies they studied, “Zero-day vulnerabilities purchased in human-machine interfaces (HMIs) of industrial control systems increased by more than 200 percent in 2018 compared to the previous year.”
Older operational technology often does not receive patches to shield against new attacks because it is not considered a vital part of patch rollout, according to TrendMicro. To be able to avoid attacks, TrendMicro recommends basic cybersecurity protections such as restricting user access and stopping directory listings, and identifying and prioritizing key assets.
“The engineer’s instinct — to keep things running and not to fiddle with something that is working — is not going to hold good for IT security, where running a process on unpatched or outdated operating systems and software opens up huge risks.” said Hannigan.
