Enhanced Security and Visibility Against ICS/OT Threats

Millions of industrial devices operate at energy, manufacturing, transportation, mining, and other industrial sites. Comprehensive cybersecurity that focuses on asset visibility proves essential in reducing risk and improving the resiliency of industrial operations. Dragos and Garland are working together to improve cybersecurity and operational reliability while reducing integration efforts and costs.

The Challenge

Traditionally, operational technology (OT) networks were architectured almost wholly separated from information technology (IT) networks. However, as industrial environments support digital transformation, they shift to a more interconnected architecture, enabling cyber threats to reach beyond the traditional IT assets. Thus, Cybersecurity teams are being challenged to secure and then manage networks that traverse their entire organization, requiring operational visibility to include the wide variety of OT and IT devices on their networks.

The Solution

The need for passive, real-time monitoring is more vital than ever in an ICS/OT environment saddled with legacy equipment. Having comprehensive visibility of the ICS/OT environment is both the tactical and strategic foundation of an effective cybersecurity program. Organizations can leverage Garland Technology’s visibility solutions to feed data to the Dragos Platform to help streamline the security of the ICS/OT network infrastructures while helping to avoid operational impacts in legacy systems. Garland’s passive network TAPs (test access points) are purpose-built hardware devices that provide essential access and monitoring capabilities in ICS/OT environments. The passive network TAPs are available in fiber and 10/100M/1000M copper models to support all legacy and modern architectures yet will not add any latency or security risk to the environment. By tapping points of interest throughout the ICS/OT network, security and other monitoring solutions can receive 100% of the traffic to enhance their defense capabilities without introducing new or manipulated traffic to the production network streams. Organizations can centrally visualize the systems, devices, and interactive communications between them by utilizing the joint Garland and Dragos solution. Additionally, they can continuously monitor and detect threats as they occur and use prescriptive workbench tools for more efficient investigations and responses. With this enhanced deep packet level of visibility across critical infrastructures, defenders can more competently protect their operations from potential disruption caused by threats and anomalies while improving their safety, reliability, and cyber resilience across their unique network infrastructures.

How It Works

Within the OT environment, a full-duplex copy of the network traffic from each site and segment is fed through the Garland network TAPs to minimize blind spots. The Garland network visibility solution delivers this duplicated traffic from multiple links and locations into the Dragos Platform. The Dragos Platform then analyzes the traffic to create an accurate and comprehensive asset inventory along with a network map that visualizes all assets' interconnections. With the continuous data feed, the Dragos Platform analyzes the network traffic and produces notifications of new devices, connections, asset vulnerabilities, misconfigurations, and other suspicious events. The Dragos Platform provides advanced threat detection, including adversary behavior and 'tradecraft,' mapped to MITRE ATT&CK for ICS for the ICS/OT network supported by Garland's complete network visibility solution.

Use Cases

Network TAPs and SPAN (switch port analyzer or port mirroring) are the two most common methods for network traffic access used by data monitoring and security analysis solutions. There are significant differences that can affect the integrity of the network device, the traffic being analyzed, and the performance of network tools leveraging the data. The following discusses three different use cases where TAPs versus SPAN options would be best leveraged in regard to monitoring the ICS/OT network.
