Ask me anything

Video - 00:02:00
Some IT solutions are dedicated to serving specific functions. In this episode, Mike discusses the security aspect of using Zigbee devices.
Smartphone hardening lab

Video - 00:03:00
Smartphones are small computers that almost everybody carries around with them. Many standard desktop computer hardening techniques can be applied to smartphones.
Exam question review

Video - 00:03:00
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 - 00:11:00
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.
Security constraints for dedicated systems

Video - 00:05:00
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.
Connecting to dedicated and mobile systems

Video - 00:11:00
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.
Internet of things (IoT) devices

Video - 00:10:00
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.
Industrial control system (ICS)

Video - 00:07:00
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).
Embedded systems

Video - 00:13:00
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.
