The convergence of Information Technology (IT) and Operational Technology (OT) has brought about unprecedented operational and financial benefits. Yet, this interconnected landscape has not emerged unscathed from the shadow of cyber threats on critical infrastructures. Now, the focus has turned to creating a robust IT/OT convergence cybersecurity system.
As nations increasingly rely on information technologies to power their growth, the implications of cybersecurity risks in critical infrastructures extend far beyond the realm of digital threats. Cyberattacks on a country's infrastructure can disrupt services, inflict economic damage, and pose risks to public order. However, the gravity of these risks transcends economic considerations, delving into the very heart of national security.
What is IT/OT Convergence?
IT/OT convergence means integrating OT devices and equipment into IT networks. Traditionally, OT systems were situated in secure, physically isolated areas, which implied security by obscurity. However, with the advance of technology and new-age solutions, IT/OT convergence rose in popularity to promote efficiency in business operations.
With this model, previously separate servers are merged with networking and management tools to create a singularly deployed and centrally managed system.
There are 3 different kinds of IT/OT convergence:
Process convergence: Workflows and organizational processes are integrated.
Software & data convergence: A kind of technological convergence involving an organization’s network architecture.
Physical convergence: Devices are fitted with newer hardware to accommodate new IT technologies.
Benefits of IT and OT Convergence
There are many benefits to merging IT and OT systems to create an interoperating ecosystem of technologies.
Direct control & monitoring of all operations, processes and devices.
Easier remote data analysis.
Real-time, actionable insights from converged data.
Shared expertise between departments with reduced isolation.
Improved security (if IT/OT networks are protected properly).
Improved compliance with better visibility, management & auditing.
Reduced development, operation and support costs.
More efficient energy & resource allocation and asset management.
The Challenges of IT-OT Convergence
The fusion of IT and OT has transformed entire industries, streamlining operations and enhancing efficiency. However, with this approach comes a new set of IT and OT security challenges. The traditional boundaries between corporate networks and operational networks are blurred, creating vulnerabilities that malicious actors can exploit. This makes it a must to recognize and improve IT/OT cybersecurity.
Different Security Priorities
IT Networks: Focus on data confidentiality and integrity, ensuring that sensitive information is protected from unauthorized access.
OT Networks: Prioritize availability and safety, ensuring that critical processes and systems operate without interruption.
Legacy Systems
OT networks often contain legacy systems that were not designed with modern cybersecurity in mind, making them vulnerable to attacks.
Increased Attack Surface
Integrating IT and OT networks expands the attack surface, providing more entry points for cyber threats.
Complex Network Architectures
The integration of disparate systems and protocols can create complex network architectures that are challenging to secure and manage.
