6 - Industrial Control Systems
Computer-management device that controls industrial processes and machines, also known as Operational Technologies (OT)
Several types
Programmable Logic Controllers (PLC)
Single-purpose or focused-purpose digital computers
Deployed for managing and automating various industrial electromechanical operations (e.g. controlling systems on an assembly line, large-scale digital light display)
Directly controls sensors, motors, valves, etc.
Distributed Control Systems (DCS)
Help to gather data and implement control over a large-scale environment from a single location
Controlling elements are distributed across the monitored environment (e.g. manufacturing floor, production line,
Centralized monitoring location sends commands out of those localized controllers while gathering status and performance data
Might be analog or digital
Coordinates many PLCs or controllers inside one facility
Supervisory Control And Data Acquisition (SCADA)
Can operate as a stand-alone device, be networked together with other SCADA systems or be networked with traditional IT
SCADA can communicate with PLC and DCS
Modbus is a widely used communication protocol in industrial automation and control systems
Security controls
Isolating networks
Limiting access physically
Restricting code to only essential applications
Changing default credentials
Logging all activity
Security standards
IEC 62443 standards for ICS
NIST SP 800-82rs
