IT vs OT: What's the difference? IT focuses on data and networks. OT controls physical processes. Discover the differences and how they affect your organization.
What is IT and OT?
Information technology, often abbreviated to IT, refers to the use of computers, networks, and other physical devices to process and manage information. IT systems are primarily based on software and network infrastructure and focus on data and information processing. This includes servers, databases, and communication networks that are essential for the functioning of modern companies.
Operational technology, on the other hand, includes hardware and systems that are responsible for controlling physical processes within an organization. OT systems focus on monitoring and controlling production processes and have the main goal of preventing unplanned downtime. Examples of OT include industrial machines, sensors, and control systems that control physical processes in factories and other industrial environments. Operational technology is essential for optimizing these processes.
Fundamental differences between IT and OT
Although IT and OT are both technologies, they are fundamentally different in their goals and practices. IT systems are primarily concerned with data and information processing, while OT systems focus on monitoring and controlling physical production processes. This difference in focus leads to different approaches and priorities within organizations.
Another important difference is the lifespan of the systems. OT systems typically have a lifespan of 10-20 years, while IT systems are often replaced within 3-5 years. This difference has major implications for how security and maintenance are planned. IT systems require frequent updates and replacements, while OT systems last longer but are therefore also more vulnerable to aging and cyber attacks.
Downtime is a crucial point of attention for OT, as unplanned production downtime involves considerable costs. The monitoring requirements of OT networks are very different from IT networks, with a focus on process automation systems. This difference in monitoring and the need for continuous availability makes OT systems unique and challenging to manage and secure.
The role of industrial protocols in OT
Industrial protocols play a crucial role in communication within OT environments. Protocols such as Modbus, OPC-UA, and Profibus are essential for automating and managing industrial processes. These protocols ensure that different devices and systems within a factory can communicate seamlessly with each other, which is crucial for the efficiency and reliability of OT systems.
Using proprietary protocols in OT, such as Modbus and Profibus, in contrast to the standard internet protocols such as TCP/IP that are used in IT, often creates additional challenges when it comes to integrations. These protocol differences can lead to communication issues and increased complexity when connecting IT and OT systems, which is an important consideration for IT/OT convergence.
Why IT/OT convergence matters
The convergence of IT and OT, also known as IT/OT integration, offers companies significant benefits. By bringing IT and OT together, companies can use real-time data for faster and better decision making, leading to increased productivity and flexibility. This enables companies to better respond to customer needs and to quickly adapt their production capacity to changing market demand.
However, this integration also involves new security risks. Cyber attacks on legacy OT systems are a growing concern, and a coordinated approach to cybersecurity is key to minimizing these risks.
Companies that effectively integrate IT and OT have less risk of falling behind in the market and can benefit from higher operational efficiency.
IT vs OT security
The security approaches for IT and OT vary significantly due to their different priorities and goals. IT systems are primarily focused on data confidentiality and privacy, while OT systems focus on availability and operational continuity. This difference requires a completely different approach to security, with IT focusing on preventing data breaches and OT on ensuring the integrity of physical processes.
Integrating IT and OT facilitates a coordinated approach to cybersecurity to mitigate vulnerabilities. Compliance and regulations are key drivers for OT teams to better secure their systems, while IT teams are more focused on prevention. This difference highlights the need for a joint strategy for effective cybersecurity in both IT and OT.
Cybersecurity challenges in OT
Cybersecurity in OT environments is hampered by the presence of legacy systems that do not support modern security measures. Nearly 50% of OT systems worldwide are still running legacy operating systems such as Windows XP, leading to increased vulnerability to cyber attacks. These legacy systems are not easily updated, so they remain attractive targets for hackers.
In addition, OT systems have limited update cycles, with updates and patches applied only once or twice a year, on average. This means that vulnerabilities often remain unresolved for longer, which increases the risk of exploits. These challenges require specific and often innovative cybersecurity solutions to secure the OT environment.
Cybersecurity Solutions for IT and OT
One of the most effective ways to improve security between IT and OT systems is to implement network segmentation. By dividing networks into separate segments, companies can limit the spread of a cyberattack and strengthen security. Data diodes can also be effective in preventing data leaks by enabling unidirectional data flow.
Regular security assessments are crucial to identify weaknesses and ensure compliance with industry standards in OT. In addition, training and awareness programs can help to make all employees aware of the cyber risks associated with both IT and OT.
An integrated security framework can significantly improve security measures for both systems.
The importance of IT and OT collaboration
Collaboration between IT and OT teams is crucial for optimizing business processes and improving operational efficiency. By integrating IT and OT, companies can accelerate and optimize their decision-making processes. This leads to a more efficient production process and better anticipation of problems.
Sharing responsibilities between IT and OT teams fosters a culture of open communication and collaboration. Cross-training for staff helps bridge the gap between both disciplines and ensures that everyone has a better understanding and understanding of the challenges and requirements of both IT and OT.
This collaboration is essential for companies that want to improve operational efficiency and gain a competitive advantage. This company plays an important role in collaborating with suppliers.
