?1. Introduction
?
In the modern industrial world, technology plays a vital role in shaping how a plant produces, functions and receives support. For large manufacturers, combining Information Technology (IT) and Operational Technology (OT) has become essential to compete in the current marketplace. This merging, known as IT-OT convergence, promises increased efficiency, better decision-making, and improved productivity.
?
However, with these great benefits come significant challenges on an operational level. One of the main concerns is ensuring that this convergence does not compromise the security of critical systems. This is where Secure Remote Access for Operational Technology (SRA4OT) becomes crucial.
?
This article aims to explain the importance of SRA4OT in IT-OT convergence projects for large manufacturers. We'll break down complex concepts into simple English, making it easy for everyone to understand.

2. Understanding IT and OT
?
Before diving into the convergence of IT and OT, it's good to understand what these terms mean, and what the difference is between them. For the sake of this article, the difference is
Information Technology (IT):
- Definition: IT refers to the use of computers, networks, storage, and other physical devices to process, store, secure, and exchange electronic data, typically outside the shopfloor.
- Examples in Manufacturing: Managing employee records, handling customer orders, overseeing supply chain logistics, and maintaining databases (non production).
?
Operational Technology (OT):
- Definition: OT involves hardware and software that monitors or controls physical devices, processes, and events within a company.
- Examples in Manufacturing: Controlling machinery on the production line, monitoring environmental conditions in a factory, and managing energy consumption.
?
Traditionally, IT and OT have operated in separate spheres. IT focused on data and information systems, while OT dealt with the physical operations of machinery and processes. The difference between a truck and a personal car. Both can be made by the same company, work on similar fuel sorts, have a similar engine build but are vastly different to work with.
Bringing these platforms together really forces IT architecture and OT architecture to learn from eachother and add a layer of protection for their respective weaknesses (Stability vs Performance)

?3. The Journey Towards IT-OT Convergence
What is IT-OT Convergence?
IT-OT convergence is the integration of information technology systems with operational technology systems. This means that the digital systems that manage data and information (IT) are combined with the systems that control physical operations (OT).
In laymans terms: using the IT landscape to support OT solutions. The IT datacenter to support the server from the OT production tools. The OT firewall to have a second tunnel in. The OT lines out, for SD-WAN
?
Why is IT-OT Convergence Important?
1. Enhanced Efficiency: Combining IT and OT allows for an increased team to work with better and more complete tools. Incidents can be seen downstream and full plant visibility gives a shorter time to respond and review
2. Cost Reduction: Integrated systems can identify inefficiencies, no need to have a duplicate of several systems. Lower need to hire several external support companies
3. Improved Product Quality: Giving your vendors, OEM's and suppliers access to your machines will ensure software updates to be done more frequently, outages spotted quicker and MTTR vastly reduced. This will ensure the higher quality and stabilty of your assets, and products as a results
?
4. Innovation: Access to comprehensive data facilitates innovation in products and processes. Panasonic welding robots are several times more efficient now, than 10 years ago. Lifecycle of a welding robot can be 20 years. Using updates will allow for better performance and increased possibilities of your assets
?
?4. Challenges in IT-OT Convergence
?
While the benefits of IT-OT convergence are clear, the path to achieving it is fraught with challenges:
1. Security Concerns:
Increased Vulnerability: Connecting OT systems to IT networks can expose them to cyber threats. OT systems, which were once isolated, become potential targets for hackers.
Legacy Systems: Many OT systems are old and not designed with modern cybersecurity in mind, making them vulnerable.
Shadow IT: Most productionplants have shadow IT present that results in direct security problems
?
2. Cultural Differences:
?? - Different Priorities: IT teams often prioritize data security and confidentiality, while OT teams focus on system availability and safety. The plant must always be running, vs let's not lose our critical data
?? - Communication Gaps: Misunderstandings can arise due to differing terminologies and approaches. These communication gaps will prevent your teams to work together
?
3. Technological Differences:
?? - Compatibility Issues: IT and OT systems will use different protocols, making integration challenging.
?? - Real-Time Requirements: OT systems often require real-time responses, which some IT systems may not be optimized for.
?
4. Compliance and Regulations:
?? - Meeting Standards: Ensuring that integrated systems comply with industry regulations can be complex.
?? - Data Privacy: Managing data across combined systems requires careful handling to protect sensitive information.

?5. Introducing SRA4OT: Secure Remote Access for Operational Technology
Given the challenges, especially in security, how can manufacturers ensure that IT-OT convergence does not compromise their operations? The answer lies in Secure Remote Access for Operational Technology (SRA4OT).
?
What is SRA4OT?
SRA4OT refers to the methods and tools that allow authorized personnel to access OT systems remotely in a secure manner. This ensures that while the systems are interconnected for efficiency, they remain protected from unauthorized access and potential cyber threats.
?
Key Features of SRA4OT:
1. Authentication: Ensures that only authorized users can access the systems.
2. Encryption: Protects data transmitted between the user and the system from being intercepted.
3. Monitoring: Keeps track of who accesses the system, when, and what changes are made.
4. Access Controls: Defines what each user can and cannot do within the system.

Why is SRA4OT Important in IT-OT Convergence?
1. Protecting Critical Infrastructure: Manufacturing operations rely heavily on OT systems. Any compromise can lead to significant losses.
2. Facilitating Remote Work: Especially in situations like the COVID-19 pandemic, the ability to manage systems remotely becomes vital.
3. Ensuring Compliance: Many regulations require strict controls over who can access critical systems.

?6. The Importance of SRA4OT in Manufacturing
Let's delve deeper into how SRA4OT benefits large manufacturers:
?
1. Enhanced Security:
?? - Preventing Unauthorized Access: By ensuring that only verified individuals can access OT systems, the risk of malicious activities is reduced.
?? - Protecting Against Cyber Attacks: Secure remote access tools often come with features that detect and prevent cyber threats.
?
2. Operational Efficiency:
?? - Quick Issue Resolution: Technicians can diagnose and fix issues remotely, reducing downtime.
