Trend Micro Industrial Network Security

What is Trend Micro Industrial Network Security?

Trend Micro Industrial Network Security is a solution for protecting industrial environments (OT/ICS/SCADA). It provides visibility, threat detection, and protection without impacting production processes.

Key differentiators:

• Passive monitoring - zero impact on industrial processes
• OT Protocol Deep Inspection - Modbus, DNP3, IEC 61850, OPC analysis
• Virtual Patching - legacy system protection
• IT/OT XDR - correlation with IT security in Vision One

Solution Architecture

Deployment Modes

Passive Monitoring (TAP/SPAN)

• Traffic copying without network impact
• Ideal for critical environments
• Full visibility without risk

Inline Protection

• Active threat blocking
• For less critical segments
• Maximum protection

Protection Features

Asset Discovery & Inventory

Automatic OT device discovery:

• Passive discovery - discovery without scanning
• Device identification - PLC, HMI, RTU identification
• Vendor detection - manufacturer recognition (Siemens, Rockwell, ABB)
• Firmware tracking - firmware version tracking

Protocol Deep Inspection

Industrial protocol analysis:

Protocol	Analysis
Modbus TCP/RTU	Read/Write commands, addresses
DNP3	Functions, data objects
IEC 61850	GOOSE, MMS
OPC UA/DA	Methods, nodes
Ethernet/IP	CIP commands
PROFINET	Function blocks

Anomaly Detection

Irregularity detection:

• Baseline behavior - learning normal behavior
• Process anomalies - unusual process values
• Network anomalies - unknown traffic, connections
• Device anomalies - unusual commands

Virtual Patching

Protection without updates:

• CVE protection - protection against known vulnerabilities
• Zero-day protection - behavioral protection
• Legacy support - Windows XP, Server 2003
• No downtime - without system restart

Protection Scenarios

Ransomware in OT

1. Detection - lateral movement detection from IT
2. Alert - notification of OT access attempt
3. Block - suspicious connection blocking
4. Forensics - attack path analysis

Insider Threat

1. Baseline - normal operator activities
2. Anomaly - unusual command detection
3. Alert - security notification
4. Investigation - activity analysis

Nation-State Attack

1. Protocol analysis - protocol manipulation detection
2. Process monitoring - process change detection
3. Threat intelligence - APT campaign correlation
4. Response - threatened segment isolation

Integration with Trend Vision One

IT/OT Convergence:

• Unified visibility - single IT and OT view
• XDR correlation - IT/OT incident correlation
• Threat intelligence - shared threat database
• Automated response - coordinated response

Regulatory Compliance

• IEC 62443 - Industrial automation security
• NERC CIP - Critical Infrastructure Protection
• NIS2 - Network and Information Security
• Local regulations - Country-specific requirements
