Securing dedicated systems

Embedded systems use their own operating system and have a defined function. Learn more about the dedicated systems used in Industrial Control Systems (ICS), IoT devices, Raspberry piIs, and Arduinos.


  • Security constraints for dedicated systems Video — 00:05:08
    • Some dedicated device security settings are limited, or patches are not available, and should be placed on isolated networks that do not contain sensitive systems or data. Mobile devices have limited CPU and battery power which limits characteristics such as the ability to quickly process cryptographic algorithms.

  • Internet of things (IoT) devices Video — 00:10:04
    • IoT devices are function-specific and can communicate over the Internet. Examples include environmental control devices, medical devices, and video surveillance systems. This episode also covers the Zigbee smart home automation protocol.

  • Ask me anything Video — 00:02:13
    • Some IT solutions are dedicated to serving specific functions. In this episode, Mike discusses the security aspect of using Zigbee devices.

  • Embedded systems Video — 00:13:19
    • Embedded systems use an operating system burned into one or more chips and have a defined function, such as running an elevator or providing Wi-Fi services. In this episode, Industrial Control Systems, Internet of Things (IoT), Raspberry PI and Arduinos are discussed.

  • Exam question review Video — 00:02:34
    • Critical infrastructure IT systems can sometimes be vulnerable to attacks. In this episode, a scenario is presented in which the best solution must be implemented to protect Programmable Logic Controllers (PLCs).

  • Mobile device deployment and hardening Video — 00:11:03
    • Organizations normally allow the use of personal or work-issued mobile devices for work purposes through provisioning schemes such as Bring Your Own Device (BYOD) and Choose Your Own Device (CYOD). This episode also discusses Subscriber Identity Module (SIM) cards and mobile device hardening.

  • Connecting to dedicated and mobile systems Video — 00:10:52
    • There are many modern wireless communication standards. This episode discussed the Global Positioning System (GPS), 4G and 5G cellular, Wi-Fi Direct, and mobile device tethering.

  • Industrial control system (ICS) Video — 00:06:43
    • ICSs use computing devices to automate tasks in a fast dependable way using Programmable Logic Controllers (PLCs). This episode also covers Supervisory Control and Data Acquisition (SCADA).

  • Smartphone hardening lab Video — 00:02:31
    • Smartphones are small computers that almost everybody carries around with them. Many standard desktop computer hardening techniques can be applied to smartphones.
