A global study by Omdia has found that 80% of manufacturing firms experienced a significant increase in overall security incidents or breaches last year, but only 45% are adequately prepared in their cyber security.
Omdia surveyed over 500 technology executives worldwide on the convergence of Information Technology (IT) and Operational Technology (OT) – or physical systems – in their core operations, and how they managed cyber security challenges. The report for the study was produced in partnership with Telstra International, the global arm of leading telecommunications and technology company Telstra.
The heightened risk of cyber attacks comes as manufacturers move to leverage IT such as cloud, AI, and Internet of Things (IoT) as part of their digital transformation – a process defined as Industry 4.0. While the convergence of IT with traditional OT can increase scale, resilience and efficiency in operations, it also increases the attack surface for cyber threats. Critical industries are increasingly lucrative targets for cyber exploitation including ransomware.
Manufacturers affected by a cyber attack reported a resilience or availability issue that cost individual firms between US$200,000 and US$2 million, taking the biggest hit when incidents affected enterprise and corporate systems or production control.
Adam Etherington, Senior Principal Analyst at Omdia, said, “Our study illuminates critical attack vectors and lessons learned, and provides timely advice for any executive responsible for IT and OT.
“More pervasive connectivity between IT and OT is essential across greenfield and brownfield manufacturing system design and enhancements. Step change improvements to innovation, availability, safety and security require firms to harness cloud, IoT, AI and private networks, with IT/OT convergence bringing these technologies to life.
“However, most firms have been hit with expensive outages and security incidents while traditional security controls, policies and culture struggle to keep pace. Given the magnitude of downtime costs from any breach or network incident that impacted operations, it’s important to better understand the causes for proactive remediation.”
