Organisations continue to struggle with device management data and fragmented architectures while facing pressure from business and regulators. As the technology landscape changes, the integration of Internet of Things (IoT) devices with Operational Technology (OT) presents both exciting opportunities and significant security challenges. In a recent episode of the Security Strategist podcast, host Christopher Steffen, alongside Dr Juergen Kraemer, Chief Product Officer of Cumulocity, examines the complexities of securing IoT environments and the importance of resilient analytics and accountability.
Understanding the IoT-OT Disconnect
As time passes, the historical divide between IT and OT persists. As highlighted by Dr Kraemer, the operational technology sector has traditionally prioritised physical safety and availability over data confidentiality. This disconnect has created a significant gap in security policies, leaving IoT devices vulnerable to exploitation. The conversation emphasises that as organisations connect these previously isolated systems to IT networks, they inadvertently expose themselves to new risks, demanding a reevaluation of security strategies.
Addressing Security Challenges
Dr Kraemer points out that securing data access is critical, especially for organisations that deploy IoT devices across multiple sites. For instance, managing security for an elevator company with installations worldwide presents unique challenges. Organisations must navigate various networks and ensure compliance with new legislative requirements, such as the Cyber Resilience Act and NIS2 directive. These regulations demand a structured approach to security that many legacy OT environments struggle to meet.
The Importance of Unified Data Management
As IoT solutions proliferate, organisations often find themselves managing a patchwork of legacy systems and newer platforms. Dr Kraemer advocates for a hybrid approach, suggesting businesses create a unified data plane that integrates new and old systems. This strategy allows organisations to maintain operational continuity while gradually transitioning to modern platforms, ultimately leading to enhanced innovation and efficiency.
Buy and Build Strategy
A significant takeaway from the podcast is the concept of “buy and build.” Instead of choosing between purchasing a platform or developing one in-house, organisations should leverage established platforms like Cumulocity while also building innovative applications tailored to their specific needs. This dual approach allows businesses to focus on high-value projects without getting bogged down by the complexities of underlying infrastructure.
The dialogue sheds light on the pressing need for organisations to adapt their cybersecurity strategies to accommodate the complexities of IoT and OT environments. By understanding the historical disconnect, addressing security challenges, and adopting a buy and build approach, enterprises can improve their cybersecurity posture and drive innovation in an increasingly interconnected world.
