Embedded Systems

Embedded Systems

  • One that has software embedded within the computer hardware, usually with a Read One Memory chip (ROM).
  • A computer system with a dedicated function within a larger mechanical or electrical system.

System on a Chip (SoC)

  • An integrated circuit that integrates all components of a computer or other electronic systems on a single computer chip.
Could not load image

Real-Time Operating Systems (RTOSs)

  • An OS intended to serve real-time applications that process data as it comes in, typically without buffer delays.
  • Designed to have zero latency.
  • Examples in Use: Military & Space applications.

Internet of Things (IoT)

  • A system of interrelated computing devices, mechanical and digital machines, objects, animals, or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
  • Wearable Technology
    • Watches, Exercise, Medical devices, etc.
    • Often communicates through bluetooth.
  • Home Automation
    • Security - Cameras, locks, lights, etc.
    • Thermostats
    • Sound Systems
    • Personal Assistants
  • Communicates via Wi-Fi

ICS/SCADA

  • ICS - Industrial Control Systems
    • Encompasses several types of control systems and associated instrumentation used for industrial process control.
  • SCADA - Supervisor Control and Data Acquisition
    • Used by Utilities and Manufacturing
    • Collects data from factories, plants, or other remote locations and forwards it to a central computer that manages or controls the system.
  • PLC - Programmable Logic Controllers
    • Single use computers used in manufacturing.
  • Security
    • Access Control
    • Monitoring

HVAC

  • Heating, ventilation, and air conditioning systems.
  • Many use computer networks or smart tech to regulate airflow and temp.
  • Security
    • Network partitioning/segmentation.
    • Access control.
    • Monitoring.

Printers / Multi-Function Devices

  • MFD - Multi-Function Devices- used for networked printing, scanning, and copying.
  • Web accessible.
  • Generally little access control.

Special Purpose Devices

  • Medical Devices
  • Vehicles
  • Aircraft / Unmanned Areal Vehicles (UAV)

Securing Embedded Devices

  • Secure by design and default.
  • Security integrated into the tech.
  • System hardening.
  • Shielded from electromagnetic interference.
  • Network security - encryption via TLS.
  • Security verification.
  • Automated patching.
  • Anomaly alerts.

Camera Systems

  • Surveillance Cameras/CCTV
  • In most cases, these cameras are connecting back to a central video recorder (DVR/NVR).
    • Often can communicate with the DVR/NVR via TCP/IP.
  • A lot of cameras are connected via PoE, so you can view what's on the camera if broken into the system.
  • IP Connected systems.
