Cyberattacks on cyber-physical systems (CPS), which include operational technology (OT) and the Internet of Things (IoT), are becoming increasingly more common, largely due to the convergence of Information Technology (IT) and OT environments. Historically, CPS operated in isolation, disconnected from broader networks. Now, many of these systems are intentionally or unintentionally linked, providing hackers with new avenues to infiltrate critical assets that are vital to our daily lives.
While the integration of IT and OT can enhance efficiency and performance, it also brings inherent risks that must be managed. The strategic importance of these interconnected systems makes them prime targets for threat actors looking to extort ransom, steal sensitive data, or disrupt operations. Therefore, understanding the dynamics of IT/OT convergence is crucial.
Understanding IT/OT convergence
IT refers to the technologies used for information management and processing, whereas OT includes the hardware and software that govern physical processes in industrial settings. Traditionally, these domains functioned independently, each with distinct systems and security protocols. However, the push for digital transformation has fostered an environment where IT and OT must collaborate more closely, prompting the need for comprehensive strategies to address both the benefits and vulnerabilities of this convergence.
Why is IT/OT convergence important?
- Increased operational efficiency: By integrating IT and OT, organizations can streamline operations, reduce downtime, and enhance productivity. This synergy enables real-time data sharing and more informed decision-making.
- Enhanced cybersecurity: A unified approach allows for better visibility into potential vulnerabilities and threats. By leveraging insights from both IT and OT environments, organizations can develop a more robust security strategy that addresses risks in a comprehensive manner.
- Improved incident response: With a converged infrastructure, organizations can respond to incidents more effectively. Enhanced collaboration between IT and OT teams ensures that threats are identified and mitigated swiftly, minimizing potential damage.
Challenges of IT/OT convergence
Despite the advantages, organizations face several challenges in achieving successful IT/OT convergence:
- Legacy systems: Many OT environments rely on legacy systems that lack modern security capabilities. Integrating these systems with IT networks can introduce vulnerabilities if not managed properly.
- Emerging threats: The combined landscape of IT and OT environments results in a more extensive and intricate attack surface. This includes hardware, software, and both on-premises and cloud infrastructures sourced from various vendors. Additionally, the rising prevalence of unsecured IoT devices and remote access to OT systems further complicates the security landscape.
- Evolving compliance landscape: Compliance requirements continue to increase, such as those related to the EU’s NIS2 Directive and Cyber Resilience Act and the updated NIST Cybersecurity Framework in the US.
- Complexity of environments: Human error poses significant challenges when organizations prioritize continuity over security. While patching vulnerabilities in IT may be manageable, doing so in CPS often disrupts critical operations. As a result, creative mitigation strategies are frequently necessary instead of direct remediation.
