OT/IoT Network Security Monitoring and Incident Detection Solution

OT/IoT Network Security Incident Monitoring and Detection Solution

Solution overview

IoT and OT systems are increasingly being deployed widely in enterprises and critical infrastructures such as manufacturing, energy, transportation and monitoring. However, the rapid increase of IoT devices such as cameras, sensors and industrial control systems also brings many cybersecurity risks.
Many serious security incidents have occurred worldwide, notably the Mirai Botnet in 2016 when hundreds of thousands of IoT devices were compromised due to default or weak passwords. In Vietnam, many surveillance camera systems have also been exploited by hackers, leading to image data leaks on the Internet.
Sonic's OT/IoT Network Security Monitoring and Incident Detection solution helps enterprises monitor OT/IoT systems, detect threats early and manage cybersecurity risks in OT/ICS environments.

Key features

Network security monitoring for OT/ICS systems

The MetaDefender OT Security solution provides security monitoring capabilities for Industrial Control Systems (ICS) and OT/IoT environments.

The system operates on a mechanism Passive Monitoring helps monitor network activities without affecting industrial system operations.

OT/IoT asset identification and inventory

Solution using tracking techniques Non-intrusive monitoring to detect devices in the OT network and build detailed asset inventory.

Asset information includes:

Device type
Protocol used
Network connection
Security status
Active ports and services

This asset inventory helps effectively support asset management and system security operations.

Visualize OT network connectivity model

System for collecting and analyzing network traffic to display network map and connection graph between devices in the OT system.

The displayed information includes:

communication protocol
gateway
communication time
data capacity

This helps administrators quickly detect abnormal connections or suspicious behaviors in the system.

Security risk and vulnerability assessment

The solution provides the capability to risk assessment and security vulnerability detection in OT systems based on databases OT ThreatFeed.

The system helps detect:

misconfiguration
outdated services
insecure network ports
potential attack threats

Unified IT/OT activity monitoring and analysis

The solution provides comprehensive visibility into all activities within the environment IT and OT convergence, helping enterprises have an overall view of the security status of the entire system.

Thanks to this, administrators can quickly detect threats and security incidents across the entire network.

Intuitive management and monitoring interface

The solution provides an intuitive management interface with various display modes such as:

Cluster View – displays connections around a device
Purdue Model View – display connections according to OT network architecture

This interface helps administrators easily track and analyze security events.

Centralized management of OT/ICS systems

The solution supports centralized administration through Central Management Console (CMC), providing real-time information on the security status of the entire OT system.

This enables enterprises to monitor and manage the entire OT/ICS environment on a single interface.

Simple deployment and flexible scalability

MetaDefender OT Security is pre-packaged with hardware and software in one appliance, enabling quick and easy deployment.

The solution offers flexible scalability for large-scale enterprises, supporting management of thousands of OT networks without impacting system performance.

Solution objectives

The solution is deployed to achieve the following objectives:

Monitor and early detect information security incidents in OT, IoT, and ICS environments
Identify and manage OT/IoT assets in the network system
Detect weaknesses and security vulnerabilities in industrial operating systems
Visualizing OT/IoT network connections helps administrators understand system architecture
Protect industrial control systems and IoT devices from cyberattacks
Support enterprises in meeting OT security compliance requirements
