Challenges and Solutions in Managing and Monitoring OT Networks

Introduction:

Operational Technology (OT) refers to the hardware and software systems used to monitor and control industrial processes, such as manufacturing, energy production, and transportation. These systems are typically used in critical infrastructure and require a high level of availability, reliability, and security. As OT systems become more complex and interconnected, managing and monitoring these networks has become increasingly challenging. In this blog, we will discuss the importance of managing and monitoring OT networks.

What is Network Managing and Monitoring?

Network managing and monitoring involve the use of tools and technologies to ensure network systems run optimally. This includes monitoring network performance, detecting and resolving network issues, and managing network devices such as routers, switches, and firewalls.

Why Is Operational Technology Network Managing and Monitoring Important?

OT networks are critical infrastructure systems that require a high level of availability, reliability, and security. Any disruption in these systems can have significant consequences, including downtime, equipment damage, and even safety hazards. Effective network managing and monitoring are, therefore, essential to ensure that these systems run smoothly and securely.

What Are Operational Technology Networking Challenges?

Here are some of the challenges network administrators face when managing and monitoring OT networks, and how managed switches can overcome them:

Network visibility: OT networks often comprise legacy devices lacking security and management features, making network traffic monitoring difficult. Managed switches can provide network administrators with visibility into network traffic, enabling them to monitor and control network traffic effectively.

Security: Cyber-attacks can result in system downtime, equipment damage, and critical data loss on OT networks. Managed switches provide network segmentation, which isolates different parts of the network and limits the potential attack surface. By segmenting the network, network administrators can ensure that only authorized traffic flows through the network.

Network performance: OT networks must operate at peak efficiency to ensure maximum uptime and productivity. Network congestion, bandwidth limitations, and other factors affect network performance. Managed switches enable administrators to prioritize traffic and set up Quality of Service (QoS) policies, ensuring that mission-critical traffic receives the necessary bandwidth and priority over other types of traffic.

Network complexity: OT networks are becoming increasingly complex, with more devices and applications added. Managed switches enable network administrators to control and configure network traffic, ensuring only authorized traffic flows through the network. It is easier to manage and monitor the network if network administrators control network traffic.

What Are Operational Technology Networking Solutions?

Here are six ways switches can be used as OT networking solutions:

Network Segmentation: Switches can provide network segmentation, which isolates different parts of the network and limits the potential attack surface. This makes it easier to manage and monitor the network, as administrators can focus on specific areas of the network rather than managing the entire network at once.
QoS Policies: Managed switches allow administrators to set up Quality of Service (QoS) policies, which prioritize traffic and ensure that mission-critical traffic receives the necessary bandwidth and priority over other types of traffic. This can improve network performance and reduce network downtime.
Redundancy: Switches can provide redundancy in OT networks. By setting up redundant links between switches, administrators can ensure that if one link fails, traffic can still be routed through the network.
VLANs: Virtual Local Area Networks (VLANs) can be set up using switches to create logical groups of network devices. This can improve network security by limiting the potential attack surface and providing more granular control over network access.
Network Monitoring: Switches can monitor network traffic and detect anomalies or suspicious activity. This can help administrators quickly identify and address security issues before they cause damage or disruption.
Network Management: Switches can provide centralized management of network devices, making it easier for administrators to configure and manage the network. This can save time and reduce the risk of errors that lead to network downtime or security breaches.

Conclusion

Managed switches play a critical role in managing and monitoring Operational Technology networks. By providing network visibility, security, network performance monitoring, and network control and configuration capabilities, managed switches enable network administrators to monitor and control network traffic effectively. This ensures that only authorized traffic flows through the network. Organizations must invest in managed switches to ensure the availability, integrity, and confidentiality of their critical data as OT networks become increasingly complex.
