The world of industrial automation has undergone a significant transformation in recent years. Once isolated from the digital realm, Operational Technology (OT) systems are now increasingly interconnected, offering numerous benefits in terms of efficiency and productivity. However, this convergence with Information Technology (IT) has also opened up new avenues for cyber threats. In this article, we will explore why your OT cybersecurity is at risk, no longer isolated, and vulnerable to cyber attacks.
Traditionally, OT systems, which include industrial control systems (ICS) and Supervisory Control and Data Acquisition (SCADA) systems, have operated in isolation from corporate IT networks. They were designed with a focus on stability and reliability rather than cybersecurity. However, the recent use of automation and the Internet of Things (IoT) has driven the integration of IT and OT. This convergence offers benefits such as real-time data exchange, remote monitoring and maintenance, and improved decision-making processes.
“Such a convergence does, to be sure, pose significant execution challenges. But an electronics company’s experience shows that for organizations that are ahead in this transition, the incremental value can add up to more than $100 million.”
The reasons behind the convergence of IT and OT are multifaceted, each contributing to the growing shift in how organizations approach their operational technology.
Challenges in the Convergence
As OT systems become more connected, they also become more vulnerable to cyberattacks. Here are some of the key challenges:
With a growing focus on OT systems, threat actors are fine-tuning their attacks to target industrial control systems (ICS) and supervisory control and data acquisition (SCADA) devices. Recent data reveals a concerning trend: reported vulnerabilities in ICS/OT systems increased by 27% in 2022. Moreover, reports indicate a substantial 87% rise in ransomware attacks against industrial organizations from 2021 to 2022.
This alarming surge underscores the immediate and critical need for organizations to bolster their OT security measures. Yet, the path to achieving this level of security is far from straightforward.
“Nearly every IT network becomes an IT-OT network, the stakes are even higher. This means that if you’ve been putting off redesigning your security systems, now is the time to make it a priority.”
Conclusion
The convergence of IT and OT has ushered in a new era of industrial automation, offering significant benefits to organizations. However, it has also exposed OT systems to the growing threat of cyberattacks. To protect your OT infrastructure, it is crucial to adapt to this changing landscape and implement strong OT cybersecurity measures. This convergence represents a pivotal shift that empowers organizations to adapt to the demands of the modern business landscape, improve operational agility, and remain competitive in a rapidly evolving digital world.
