What is the difference between IT and OT?
IT environments are designed to oversee and process the flow of data and information through various systems. This includes servers, computers, software, databases, and other tools that facilitate communication, store data, and conduct analysis. The core function of IT systems is to manage the data and information that drive business operations.
In contrast, OT focuses on controlling and managing physical devices used in producing or delivering goods and services. OT systems, like industrial control systems (ICS), sensors, and robotics, are vital in industries that rely on critical infrastructure. The primary task of OT systems is to regulate and automate physical processes and machinery crucial to business functions. In essence, while IT centers on data and communication, OT is dedicated to controlling physical operations and outcomes.
Why cyber security is essential in OT and IT?
Cyber security is essential in both Operational Technology (OT) and Information Technology (IT) because the increasing connectivity between these two domains exposes critical systems to new vulnerabilities. Traditionally, OT systems were isolated from the public internet and internal networks, limiting access to authorized personnel only. However, with the rise of connected devices and the integration of OT with IT systems, these protections are no longer sufficient. IT now plays a crucial role in monitoring OT systems, providing real-time data, and addressing errors quickly, which helps prevent industrial accidents and unplanned downtime. As OT systems become more integrated with IT, the need for strong cyber security measures becomes even more critical to protect against potential threats.
The convergence of IT and OT has made cyber security a shared responsibility, with each domain’s security measures complementing the other. While IT security focuses on safeguarding data and communication networks, OT security is tasked with protecting the physical infrastructure that underpins critical operations. As OT systems increasingly rely on IT security protocols to detect and respond to cyber threats, the collaboration between IT and OT security teams becomes vital. This interconnected approach helps to mitigate the risks associated with the growing number of cyber attacks targeting OT systems, ensuring the safety and reliability of both digital and physical assets.
Way forward
Strengthening cyber security across both Information Technology (IT) and Operational Technology (OT) environments is crucial for safeguarding your organization. To support this, Security Quotient’s research team has developed an informative carousel titled ‘Cyber Security in Information Technology vs. Operational Technology.’ This guide highlights the differences in IT and OT systems and provides IT and OT Managers, Industrial Control System (ICS) Specialists with insights to enhance security in both areas effectively.
