Overview

Operational Technology (OT) threat modeling involves systematically identifying and analyzing potential security threats to industrial control systems and critical infrastructure. It addresses the unique challenges of securing OT environments, which often combine legacy systems with modern networked components.

Primary Security Objectives

Identification and mitigation of risks such as unauthorized access, sabotage, and system disruptions
Enhancement of system resilience and continuity of industrial processes
Focus on protection and detection, with emphasis on incident response planning and governance frameworks

Where It Is Used

Industrial control systems (ICS), supervisory control and data acquisition (SCADA) networks, and other OT environments
Critical infrastructure sectors including energy, manufacturing, transportation, and utilities
Organizations managing complex industrial processes requiring high availability and safety standards

How It Works (High Level)

OT threat modeling involves creating structured representations of OT systems to identify potential attack vectors, vulnerabilities, and threat actors. It incorporates analysis of system architecture, communication flows, and operational dependencies to prioritize risks and guide mitigation strategies.

Key Capabilities

System and asset inventory mapping specific to OT environments
Threat identification tailored to industrial protocols and operational constraints
Risk assessment frameworks that consider safety, availability, and integrity impacts
Scenario analysis to evaluate potential attack paths and consequences

Benefits and Limitations

Improves understanding of complex OT environments and associated risks
Supports proactive security planning and enhances incident response readiness
May be challenged by limited visibility into legacy systems and proprietary technologies
Requires specialized knowledge of both cybersecurity and industrial operations

Integration and Dependencies

Integration with asset management, vulnerability assessment, and incident response tools
Dependence on accurate system documentation and operational data
Collaboration between IT security teams and OT engineers is essential for effective modeling
