IT/OT convergence is the integration of data management systems (IT) with industrial operation systems (OT).

This integration allows for real-time data exchange, enhancing the efficiency and effectiveness of both systems. Industries benefit from improved decision-making and operational processes, grounded in accurate, timely data.

## What Is OT?

![Six icons representing Operational Technology components: Machinery, Monitoring, HMIs, RTUs, PLCs, SCADA Software.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/operational-technology-ot.png "Six icons representing Operational Technology components: Machinery, Monitoring, HMIs, RTUs, PLCs, SCADA Software.")

Operational Technology (OT) refers to the combination of hardware and software designed to manage, control, and oversee physical equipment and processes in sectors like manufacturing, energy, and telecommunications.

It utilizes technologies including Industrial Control Systems (ICS) and Supervisory Control and Data Acquisition (SCADA) systems to oversee, manage, and automate industrial activities in real time. Although legacy systems are still prevalent in OT, there is a noticeable shift towards more contemporary integrations due to technological advancements.

OT plays a crucial role in amplifying the efficiency, security, and dependability of industrial processes. It achieves this by offering instantaneous feedback and control mechanisms, reducing downtime and boosting output.

Distinct from Information Technology (IT), OT is characterized by its direct engagement with industrial machinery and procedures, with a concentration on tangible environments and operational necessities.

## What Is the Difference Between IT and OT?

![Comparison chart of IT versus OT highlighting differences in focus, environment, connectivity, and data management.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/it-vs-ot.png "Comparison chart of IT versus OT highlighting differences in focus, environment, connectivity, and data management.")

IT and OT serve distinct roles within an organization. IT is primarily concerned with managing and processing data to ensure its availability, confidentiality, and integrity. Its domain includes computers, servers, and similar devices that handle data storage, retrieval, and transmission tasks. OT, on the other hand, is tasked with controlling and monitoring physical processes and equipment, ensuring operational effectiveness and safety within industrial settings.

The environments in which IT and OT operate are markedly different. IT functions within a general computing environment and deals with standard operating systems for data-centric tasks. In contrast, OT is tailored for industrial settings, employing specialized, often proprietary systems to meet specific operational requirements.

Security considerations also vary. IT security emphasizes data confidentiality, while OT security is centered on the safety and availability of physical processes and equipment. System maintenance and updates in IT are frequent and regular, whereas OT prioritizes uninterrupted operation, scheduling updates during specific maintenance windows to avoid operational disruptions.

Connectivity and data use and processing distinguish IT and OT as well. IT is characterized by its connectivity, enabling data exchange and communication over networks. OT has traditionally been more isolated but is becoming increasingly connected due to the integration of Industrial Internet of Things (IIoT) technologies. While IT handles a diverse range of data types and focuses on broader business data needs, OT is concentrated on real-time data processing essential for monitoring and controlling industrial equipment and processes. The specific and immediate use of data in OT is crucial for maintaining operational efficiency and safety.

## How and Why IT and OT Are Converging

Traditionally, Information Technology (IT) and Operational Technology (OT) have existed in separate domains within organizations, each performing distinct functions. However, a transformation is underway, characterized by the systematic integration of these two previously isolated worlds, leading to what is known as IT/OT convergence.

This convergence is propelled by digital transformation and advances in technologies like the Internet of Things (IoT) and big data analytics. The merging of IT and OT enables a seamless flow of data between the digital and physical worlds, bridging the gap between data management systems and industrial operations. The digital information world can now not only visualize but also influence the physical operational world, leading to enhanced efficiency and innovation in business processes.

One of the core advantages of IT/OT convergence is increased efficiency. It facilitates the integration of different technologies to work as a single, cohesive system, reducing errors and enhancing workflows. This integration means that data from physical operations (OT) can be quickly analyzed and influenced by IT systems, allowing for more informed decision-making and autonomous operation which improves accuracy and uptime.

The core of IT/OT convergence is the ability to enhance the value delivered by both IT and OT systems. It fosters a level of interconnectivity that streamlines operations, fosters innovation, and introduces new services. This integration is becoming increasingly pivotal in the era of Industry 4.0 and IIoT.

## Types of IT/OT Convergence

![Venn diagram showing types of IT/OT convergence: physical, organizational, and software.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/types-of-convergence.png "Venn diagram showing types of IT/OT convergence: physical, organizational, and software.")

IT/OT convergence is not a monolithic concept, but a multifaceted initiative tailored to the specific organizational needs and goals.

Each type of convergence---physical, software, and organizational---addresses distinct aspects of the integration process. For example, this includes direct connection of devices, seamless data flow, and the harmonization of organizational workflows.

### Physical Convergence

Physical convergence is a fundamental type of IT/OT integration where OT devices are directly connected to IT networks. It often involves modernizing or retrofitting older OT equipment to facilitate this connection. In this setup, OT devices enhanced with connectivity features can transmit data directly to IT systems for analysis and decision-making.

### Software Convergence

Software convergence allows OT data to integrate with IT systems, promoting efficient information flow. The data from OT systems is collected and analyzed digitally by IT systems to improve operational efficiency. This process is crucial for real-time data processing that enhances operational control and decision-making.

### Organizational Convergence

Organizational convergence involves merging the workflows of IT and OT departments to build a unified operational system. Even though IT and OT can function separately, sharing information consistently is essential. The process requires refining business operations to let IT and OT support and enhance each other's work, aiming to improve communication and teamwork.

## The Role of IoT and IIoT in IT/OT Convergence

The advancement of the Internet of Things (IoT) and Industrial Internet of Things (IIoT) significantly influences IT/OT convergence.

Traditional OT devices, such as sensors, were not designed for network connectivity. This limits their function to data collection without the ability to transmit this data over a network. IoT devices are networked computing entities. They are adept at collecting, transferring, and analyzing data, and play a pivotal role in facilitating IT/OT convergence.

In the industrial context, IIoT enhances the potential of IT/OT convergence by empowering OT devices with real-time data processing capabilities. This transformation is realized through the incorporation of smart sensors on industrial equipment, enabling these devices to collect and transmit data to IoT hubs or gateways. For example, on a factory floor, enhanced sensors can gather operational data and relay it over wireless networks to back-end system applications. Applications then interpret data to inform immediate actions, such as equipment maintenance, ensuring timely interventions and minimizing downtime.

The synergy of IoT and edge computing amplifies the efficacy of IT/OT convergence in industrial settings. Edge computing allows IIoT devices to process data in real time closer to the source. This reduces the need to transmit vast amounts of data over networks to centralized locations for processing. This capability is crucial in distributed network architectures common in industrial environments. In industrial environments, immediate data insights are essential for monitoring

## IT/OT Security Convergence

![Comparison chart of IT vs. OT security priorities: confidentiality, integrity, and availability.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/comparing-it-and-ot-security-priorities.png "Comparison chart of IT vs. OT security priorities: confidentiality, integrity, and availability.")

As IT and OT environments converge, there's an adjacent convergence of IT and OT security.

Traditionally, IT security focuses on protecting data and maintaining the confidentiality, integrity, and availability of information. OT security is more concerned with ensuring the availability, integrity, and reliability of industrial processes in addition to the safety of human lives and the environment.

In the context of IT/OT convergence, security must be holistic, addressing vulnerabilities and risks inherent in both environments. This convergence involves the integration of security policies, practices, and technologies to protect the entire organization's ecosystem, covering data and industrial processes. This is important because as OT systems become more connected, they become more vulnerable to cyber threats that have traditionally targeted IT systems. A unified approach to security that covers both IT and OT environments is critical in today's interconnected, increasingly digital world.

IT/OT convergence brings about significant efficiency and data utilization advancements, but also introduces security challenges. With IT systems designed for data processing and OT focusing on the control of physical processes, their convergence creates a complex landscape. Security protocols of one may not seamlessly integrate with the other. The integration often exposes OT to cybersecurity threats, increasing the need for comprehensive security strategies that encompass both realms.

A notable challenge stems from OT systems' enduring nature compared to the shorter lifecycle of IT infrastructures. OT systems are designed to last decades. Because of this, they often lack the built-in security features inherent in their IT counterparts. A prolonged lifecycle, coupled with proprietary designs, complicates advanced security protocol integration. The legacy nature necessitates thorough security assessments, and in some instances, comprehensive upgrades to meet converged environment security demands. Updates frequently require revisiting the concept of air gapping -- the division between operational technology and IT systems that are connected to the internet.

The continuous, mission-critical nature of OT systems poses further security complexities. OT environments often cannot afford downtimes for updates or maintenance without incurring substantial operational and financial impacts. This can sometimes lead to postponed security updates, which creates vulnerabilities. The incorporation of IoT and IIoT enhances real-time data processing and analytics but also expands the attack surface for potential cyber threats.

For secure IT/OT integration, security strategies must evolve to safeguard the integrity, confidentiality, and availability of data. Organizations must balance the need for operational continuity with stringent security protocols.

## Impacts of IT/OT Convergence on ICS Security

With the arrival of IIoT, every ICS sensor, instrument and device accessible over an IT/OT network is susceptible to weaponization. ICS sensors can be vulnerable to botnets used to launch targeted attacks on critical infrastructure. This includes energy grids, power plants, water and waste management systems, food processing plants, and transportation networks.

The human-machine interface (HMI) that connect operators to industrial control systems are also typically networked to various IT infrastructures. Accessibility to HMIs from internet-facing business networks poses a risk to ICS security, making HMIs susceptible to IP-based vulnerabilities. IP-based vulnerabilities can include authentication bypass, weak session management, unsecured ICS communication protocoling and insufficient control traffic encryption.

Attackers typically infiltrate ICS systems with both generic malware and malware designed specifically to target and attack critical infrastructure. These infiltrations often result in denial-of-service, or DoS, attacks that paralyze or halt industrial operations. ICS and connected IIoT devices are also high-value targets for hackers looking to collect ransoms or sabotage rival nations by gaining access to confidential data.
