Business & Technology
Digitization is transforming how businesses operate. This transition is often referred to as the Fourth Industrial Revolution or Industry 4.0 because it represents the fourth manufacturing revolution. The first industrial revolution was mechanization, the second was mass production and assembly lines using electricity, and the third was the adoption of computers and automation.
Now the Fourth Industrial Revolution is upon us, with the digital transformation of businesses largely consisting of automation, artificial intelligence (AI), and rapid technological innovation. Industrial processes and machines are becoming smarter and more modular, with automation and data exchange that include the Internet of Things (IoT) and the Industrial Internet of Things (IIoT). These smart, always-connected devices provide real-time contextual information with low overhead to optimize processes and improve how companies and individuals interact, work, and live.
It's no wonder McKinsey estimated that investments in IoT technology would grow at a rate of 13.5% throughout 2022. This growth in IoT is contributing to an escalating explosion in production and industrial data. This data is being collected and analyzed to improve productivity, monitor activity, and enhance predictive maintenance. With so much business-critical data passing through IoT and IIoT devices, organizations must take measures to secure their technology.
Digital has not gone unnoticed by cybercriminals, who seek to exploit IoT and IIoT as weak links in the data chain. The increasing volume of structured and unstructured data being generated by these devices, and their oftentimes anomalous behavior spanning across global ecosystems challenges even the best organizations. Further complicating the situation is that many of these devices are wireless (WLAN or 5G) and often have communication channels to their manufacturers for maintenance and troubleshooting purposes, which can make them a potential backdoor into the production network.
Most organizations are not well prepared for IoT and IIoT device vulnerabilities. The ubiquitous interconnectivity among devices, users, and distributed networks presents a substantial challenge for traditional siloed security solutions. Focusing defenses on a single point in the network is becoming increasingly ineffective. The lack of single-view visibility across devices, users, and the entire network creates blind spots that cybercriminals can exploit. According to a study conducted by EY, almost half of enterprises indicate they are concerned about their inability to track security across their IoT and IIoT assets, keep them virus-free, and patch vulnerabilities. This complexity is exacerbated by comingling IIoT devices with wired devices on the same network segments, and can lead to uncertainty as to exactly what is connected where.
From a security perspective, IoT and IIoT devices present a number of risks. One problem is that most of these devices were not designed with security in mind. Many of them are headless, which means they do not have a traditional operating system or even the memory or processing power required to include security or install a security client. In addition, an alarming number of devices have passwords hard-coded into their firmware.
The result is that many IoT devices cannot be patched or updated. And even when security can be installed on the device, the underlying installed software is often cobbled together from commonly available code or is untested, which means that most installed security tools can be circumvented by exploiting a wide range of known vulnerabilities. Additionally, most IIoT and IoT devices have limited or no configurability. And when devices are compromised, most IT organizations admit they are unlikely to be able to detect the event before it impacts systems and data.
Some organizations are working to address these issues by promoting authentication, key, and credential management, and other capabilities. But these tools must be tested, integrated with the network architecture, updated, managed, and monitored. So, what is the answer? Simply sticking your head in the sand will not work. IoT and IIoT devices are a vital part of most businesses and they are here to stay. It is important to view IIoT as part of your broader security environment rather than as isolated units. Here are a few additional recommendations for securing this technology:
Unfortunately, IIoT devices are typically not designed with security in mind and finding ways to secure every device on your network is daunting. Because of this, organizations must take immediate action to protect their systems from attack.
A new generation of tools is helping organizations meet today’s ever-expanding attack surface, delivering not only visibility of the network environment, but also enforcement and dynamic policy control. Whether devices are connecting from inside or outside the network, they can automatically respond to compromised devices or anomalous activity.
Fortinet has developed products, services, and tools that directly meet the operational and regulatory requirements of industrial and manufacturing networks. The expansive Fortinet Security Fabric platform offers a cybersecurity mesh architecture approach that includes centralized management and a unified context-aware security policy that provides complete visibility and granular control over the entire organization.
Find out how the Fortinet Security Fabric platform delivers broad, integrated, and automated protection across an organization’s entire digital attack surface to deliver consistent security across all networks, endpoints, and clouds.
