Industrial Cybersecurity: Safeguarding the Digital Evolution of Manufacturing

Summary: Industrial cybersecurity focuses on protecting IT-OT networks and industrial control systems (ICS) from cyber threats. It involves a variety of practices and technologies designed to protect industrial systems against cyberattacks, unauthorized access, and other digital vulnerabilities. In this blog, we have discussed Industrial cybersecurity in detail, potential cyber threats, solution deployment types, and international standards to manage information security and operation technology.

Industrial solutions are going digital – the digital transformation wave is sweeping industries around the globe, and manufacturing setups are becoming more IT, OT, and ICS-driven. Moreover, factories are becoming more connected and smarter with industry 4.0 solutions powered by IIoT, cloud solutions, and AI-ML-based analytics – transforming production facilities end-to-end from digitizing sourcing, R&D, product engineering, factory operations, and supply chains.

This digital evolution has made connected peripherals and ICS networks highly vulnerable to cyber threats and attacks that grow more sophisticated by the day, posing a tough challenge for manufacturing enterprises. If not addressed timely, these threats can disrupt or damage plant operations and IT systems by hacking vital information. That is why industrial cybersecurity is gaining high importance and becoming an inevitable component of this digitalization revolution.

Understanding Industrial Cybersecurity and Potential Threats

A recent report highlights the global Industrial Cybersecurity market to grow to USD 24.4 Bn by 2028, reason being mounting cyber threats on industrial IT systems and plants that could cripple operations. The challenge for any digital enterprise with increased connectivity of IT and OT is to manage massive volumes of industrial data optimally and securely, failing which may result in compromised plant operations, production, and supply chain downtime.

Industrial cybersecurity is essential for safeguarding the information and operational technology (OT) systems within industrial environments, such as manufacturing plants and critical infrastructure.

OT-IT integration and IIoT connectivity introduce new vulnerabilities into industrial systems – threats like malware can access and corrupt enterprise-sensitive data and disrupt operations. At the same time, phishing may result in malicious software being integrated into IT systems. IoT vulnerabilities may disrupt industrial connectivity solutions. Service providers need to be vigilant towards such diverse cyber threats.

For any industrial cybersecurity service provider, it is essential to understand what assets, processes, and plant peripherals need to be secured first, followed by understanding IT vulnerabilities and OT threats. Then comes the implementation part, where cybersecurity solutions are designed as per enterprise requirements, and countermeasures are applied. Finally, cybersecurity assets, activities, and resources should be prioritized.

Industrial Cybersecurity Solution Deployment Type

Every enterprise has unique security needs. There are a variety of components ranging from hardware equipment, IT assets, storage, backup, servers, software, and other cloud services that integrate with machines and systems in an enterprise to deliver IT OT infrastructure. That is why when cybersecurity experts design the infrastructure for enterprises it’s important for them to gain a comprehensive view of their landscape, infrasturure, requirements and long-term goals to ensure a proper and efficienct cybersecurity ecosystem. Let’s discuss the on-premise and cloud security solutions as deployment types for industrial cybersecurity solutions

• On-premise deployment: On-premise cybersecurity deployment in manufacturing setups are customized solutions per the organization’s policies and protocols. These are low-latency solutions and have faster response times. Also, on-premises solutions help in implementing strict network segmentation in isolation separating sensitive data and systems from the overall network. These on-premises cybersecurity solutions ensure business continuity with proper cybersecurity measures in place. While there are a few advantages, on-premise industrial cybersecurity solutions also face scalability challenges due to limits to the on-premises storage capacity of the servers and data processing power. Simply put, after a threshold limit, data generated by the connected IT OT industrial systems cannot be properly processed with speed and accuracy.
• Cloud-based deployment: Cloud-based deployment of industrial cybersecurity solutions has higher operational efficiency and cost savings over conventional on-premises setups. Since all the data is stored in the cloud, such solutions are highly scalable and easily accessible. Cloud-based industrial cybersecurity ensures system integrity and network security, extending to plant security. Through centralized visibility with continuous monitoring of industrial systems like connected devices in production setup, ICS, network usage, and more, these solutions also offer regular vulnerability assessments – enabling proactive and preemptive steps against potential cyber threats.

 
Numerous parameters can be deployed to select the right security solution for an enterprise, including software type, industrial data rights and protection, data storage capacity, threat detection and identification, and investment and maintenance. However, it entirely depends on the enterprise; if they don’t want their critical data to be stored on a shared, private network and are ready to deploy more professionals to monitor security solutions, they can choose on-premise solutions. On the other hand, if a company needs a scalable and flexible security solution with built-in incident response and investigation tools, they can go for cloud-based industrial cybersecurity solutions.

Standards for Industrial Cybersecurity

To address the challenges of increasing cyberattacks in industrial environments and their critical infrastructure, the International Electrotechnical Commission (ICE) has developed a series of standards known as IEC 62443. This standard primarily focuses on securing operational technology (OT) systems and their data and addresses various aspects of industrial cybersecurity, helping organizations effectively implement robust security measures.

The documentation comprised under ICE 62443 covers various aspects of industrial cybersecurity. It talks about network segmentation (limiting the spread of malware and unauthorized access), guidelines for risk assessment, security program development, and incident response planning. It also talks about designing and implementing secure industrial control systems, as well as components comprised of embedded devices, control systems, and software.

On the other hand, ISO/IEC 27001 is also an important international standard for managing information security, which applies to any organization, irrespective of industry. ISO 27001 helps secure information security management systems (ISMS) and provides a general framework for information security. ISO 27001 offers a high degree of customization, allowing organizations to adapt the framework to meet their specific needs. However, it may not address the unique challenges industrial systems encounter as comprehensively as IEC 62443.
