How Omnis Detects Attacks on IoT and OT Networks

In today’s world, where industrial networks are becoming increasingly interconnected, the problem of OT network security is of paramount importance. The integration of IoT devices into ICS offers significant advantages in terms of automation and efficiency, but also creates new vulnerabilities, making industrial networks a prime target for attackers. Imagine a situation: your industrial controllers suddenly fail, production processes stop, and you discover that the cause is a compromised IP camera connected to the same network. It is to prevent such scenarios that Omnis is designed – a solution that provides comprehensive ICS security and IoT security in industrial environments.

OT Security Threats: Why SCADA network monitoring is so important

Traditional protection methods focused on IT infrastructure are often ineffective in OT environments. Differences in protocols, operating systems, and requirements for fault tolerance make ICS security a unique challenge. Outdated systems, the inability to quickly install security updates, and, as a rule, the lack of adequate network segmentation create fertile ground for attackers. OT network security requires a specialized approach that takes into account the specifics of industrial protocols and processes.

Main OT security challenges:

• Variety of protocols:

industrial networks use many specialized protocols that are not always supported by standard security tools.

• Outdated systems:

many industrial systems run on outdated software that does not receive security updates.

• Limited resources:

industrial devices often have limited computing resources, which makes it difficult to install and operate resource-intensive security tools.

• High availability requirements:

stopping industrial processes to install updates or perform maintenance can lead to significant losses.

Omnis: A comprehensive solution for OT network security

Omnis is a platform designed to provide ICS security and detecting attacks on industrial networks. It provides complete visibility into network activity, identifies anomalies and suspicious behavior, and helps prevent unauthorized access to critical systems. The Omnis architecture is designed to minimize the impact on production processes and provide continuous protection.

Main functional capabilities of Omnis:

• Automatic device inventory:

Omnis automatically discovers and identifies all devices connected to the network, including IoT devices and industrial controllers.

• Network traffic analysis:

Omnis analyzes network traffic in real time, identifying anomalies and suspicious behavior.

• Intrusion detection:

Omnis uses signature-based and behavioral analysis to detect known and new attacks.

• Vulnerability management:

Omnis identifies devices with known vulnerabilities and provides recommendations for their elimination.

• Report Generation:

Omnis provides detailed reports on the security status of the network, which help to comply with regulatory requirements.

How Omnis Provides IoT Security and OT Networks: Technical Details

Visibility and Inventory of IoT Devices

The first step towards ensuring IoT security and OT networks is to obtain complete visibility of all connected devices. Omnis uses passive network scanning to automatically discover and identify all devices, including industrial controllers, sensors, surveillance cameras, and other IoT devices. The platform collects information about the device type, manufacturer, firmware version, and other characteristics, allowing you to create a complete and up-to-date network map. This is especially important in situations where many IoT devices are added to the network without the knowledge of the IT department.

OT Protocol Analysis: A Deep Understanding of the Industrial Network

Omnis supports a wide range of industrial protocols, including Modbus, DNP3, IEC 60870-5-104, and others. This allows the platform to analyze traffic at the protocol level, identifying anomalies and attempts by attackers to exploit vulnerabilities in these protocols. For example, Omnis can detect unauthorized attempts to write to controller registers or change device configurations. Deep analysis of OT protocols is a key element of ICS protection.

Behavioral Analysis and Machine Learning for Detecting Attacks on Industrial Networks

Omnis uses advanced behavioral analysis and machine learning techniques to identify anomalies and suspicious behavior on the network. The platform builds baseline profiles of normal activity for each device and each user, and then identifies any deviations from these profiles. For example, Omnis may detect that a device that normally only exchanges data with certain servers has started sending data to an unknown IP address. These technologies allow Omnis to detect not only known, but also new, previously unknown attacks.

Integration with SIEM and other security systems

Omnis easily integrates with existing SIEM systems and other security solutions, such as firewalls and intrusion detection systems. This allows organizations to centrally manage the security of their IT and OT infrastructure and quickly respond to security incidents. Omnis can send notifications about detected anomalies and suspicious behavior to the SIEM system, where they can be processed and analyzed by security analysts.

Benefits of Omnis for OT network security

Omnis offers a number of key benefits that make it an indispensable solution for ensuring OT network security:

• Improved Visibility:

Omnis provides complete visibility of all devices and network activity in the OT network, allowing you to identify anomalies and suspicious behavior.

• Early threat detection:

Omnis uses advanced behavioral analysis and machine learning techniques for early threat detection, which helps prevent serious security incidents.

• Risk reduction:

Omnis helps organizations reduce the risks associated with ICS security and IoT security.

• Compliance with regulatory requirements:

Omnis helps organizations comply with regulatory requirements, such as NIST 800-82 and ISA/IEC 62443.

• Minimizing the impact on production:

Omnis uses passive network scanning and does not affect production processes.

Omnis is not just a SCADA network monitoring tool, it is an investment in the sustainability and reliability of your industrial processes. By implementing Omnis, you gain confidence that your OT network is reliably protected from modern cyber threats.
