After Covid, operational technology has become more digitalized, boosting productivity and quality. Connected machines and digital workplaces show great growth potential for sectors like manufacturing, energy, logistics, and transportation. However, as many industries digitize their processes, this brings new threats to contend with. Moreover, increased digitalization also heightens the risk of cybercrime.
Digital transformation in modern OT
Decoding key challenges
Connected devices
The rise of Internet of Things (IoT) has increased the integration of devices like sensors and controllers into operational technologies, escalating cybercrime threats. Here’s how.
IT/OT convergence
In the past, IT and OT were separate entities with no interactions. Currently, OT is increasingly adopting IT technologies to enhance productivity, which increases the possibility of security breaches. Every Industrial Control System (ICS) sensor, machine, and device can become a new entry point for hackers to gain access into critical infrastructure such as factory floors and energy grids.
Ransomware attacks
An example that underscores the risks associated with ransomware involves an Indian manufacturer that suffered a severe malware attack. This attack resulted in a ransom demand exceeding $5 million. Within one hour, 450 machines were rendered inoperative, and within the subsequent hour, three factories halted their operations completely. The entire IT infrastructure was compromised, leading to significant production downtime.
Supply chain vulnerabilities
A company’s strength relies on its supply chain. Without a proper supply, production halts and costs rise. critical systems and OT environment. With increasing digital processes, securing the supply chain is essential to prevent hacker access.
Factors affecting the future of operational technology
Operational technology (OT) is rapidly evolving, driven by advancements in digital transformation and the integration of IT and OT systems. As we look to the future, several key trends are set to shape the landscape of OT.
1. Integration of IoT and IIoT
The adoption of Internet of Things (IoT) and Industrial Internet of Things (IIoT) devices is reshaping OT systems. These devices offer enhanced efficiency and real-time data insights but also create new security challenges. In smart factories, IIoT sensors monitor machine performance, environmental conditions and product quality in real time. This data helps optimize operations, predict equipment failures and automate quality control, leading to reduced downtime. In transport and logistics, IIoT devices enable real-time tracking of vehicles and shipments, predictive maintenance and smart logistics. These, in turn, improve operational efficiency, reduce costs and enhance customer service.
2. Advancements in AI and Machine Learning
Artificial Intelligence (AI) and Machine Learning (ML) are set to revolutionize OT environments. Modern factories use advanced technologies like AI and IoT to optimize their production. Some employ over 200 robots to assist in manufacturing processes. They use digital twins with AI to simulate changes and predict risks. Solutions like these are already used in factories of major players like Tesla, GE, Siemens, and Infineon. These companies see the value of integrated AI and ML in enhancing their manufacturing process. Additionally, it is worth knowing that these technologies can improve your cybersecurity operations in terms of predictive analytics, automated threat detection, and behavioral analysis, significantly enhancing threat response capabilities.
3. Reinforced regulatory frameworks
In tandem with NIS2, these frameworks show the fast-rising need for a globalized standard of cybersecurity measures. They cover aspects of risk assessment, security policies and technical controls to protect against cyber threats in industrial environments. They emphasize the importance of continuous auditing, real-time monitoring and reporting to ensure compliance while bolstering security.
Additionally, the Cyber Resilience Act (CRA) establishes common cybersecurity standards for products with digital elements, such as mandatory incident reporting and automatic security updates. It aims to ensure that digital products are secure throughout their lifecycle, rebalancing responsibility towards manufacturers. This regulation enhances existing frameworks by offering a holistic approach to cybersecurity, guaranteeing that both hardware and software products adhere to strict security standards before they are allowed on the market.
