Study Notes
OT and OT Security
- OT (Operational Technology) refers to hardware and software that detects or causes change through direct monitoring and/or control of industrial equipment, assets, processes, and events.
- OT security involves practices and technology used to protect people, assets, and information in OT environments.
Industries Where OT is Used
- Manufacturing
- Automotive
- Medical systems
- Military systems
- Power
- Refineries
- Pipelines
- Chemicals
- Water
Main Focus of Security in IT vs OT
- IT: Confidentiality, integrity, and availability of systems and data
- OT: Safety - the physical well-being of people, equipment, and the environment, preventing injury and damage
Main Components of OT
- ICS (Industrial Control Systems)
- SCADA (Supervisory Control and Data Acquisition)
- PLCs (Programmable Logic Controllers)
- IEDs (Intelligent Electronic Devices)
Functions of OT Components
- SCADA: Collect data from sensors at remote locations and send it to a central computer for control
- PLCs: Connect sensors and RTUs to the SCADA system, collecting and passing data in real time
- IEDs: Issue commands to power system equipment (like circuit breakers) based on data from sensors
Components of SCADA
- Sensors
- PLCs
- RTUs (Remote Terminal Units)
- DCS (Distributed Control Systems)
IIoT and OT Security Framework
- IIoT (Industrial Internet of Things)
- Five core functions of an OT security framework:
- Asset Identification/management
- Access control
- Network segmentation
- Logging and monitoring
- Risk management
Fortinet Products for OT Security
- NGFW (Next-Generation Firewall)
- FortiNAC (Network Access Control)
- FortiSIEM (Security Information and Event Management)
- FortiAuthenticator
- FortiClient
- FortiToken
- FortiSOAR (Security Orchestration, Automation and Response)
Security Measures for OT
- IT/OT boundary: the most critical boundary in OT segmentation
- Electronic Access Point (EAP): the critical access point in the NERC-CIP standard
- Logging and reporting: crucial for threat hunting, auditing, and incident response
- Risk management: evaluating potential risks and consequences to implement appropriate controls
Industry Standards and Frameworks
- IEC 62443: the most important standard for OT security across all sectors
- NIST Cybersecurity Framework: integrates industry standards and best practices for managing cybersecurity risks
- Purdue Model: defines segmentation of OT networks based on operational needs
- IEC 62443 standard: defines four security levels (Level 1: Casual exposure, Level 2: Intentional attack with low resources, Level 3: Intentional attack with moderate resources, Level 4: Intentional attack with extensive resources)
