Embeded Systems Flashcards
RTOS real time operating system
This is an embedded system closed loop component, RTOS defines the way the system works. May become outdated, often patches are not available, iOS strongly incentive using open source OS
Active side channel
This is attack for embedded system, uses a voltage glitch on the power supply, to cause a program malfunction
SCADA supervisory control and data acquisition
Refers to centralized industry control systems (ICS), monitor complex systems spread over large areas (electrify, gas, water). Threats include cyberattacks politically motivated. VULNS: outdated OS, authentication mechanisms, limited monitoring, limited maintenance windows
Raspberry pi
Is a series of small, single-board Linux embedded systems developed by Raspberry PI foundation to promote teaching of basic computer science
SSH secure shell
Cryptographic telnet replacement
ICS industry control systems
Are embedded systems that monitor and control industrial process that exists in the physical world. Are either data - driven or operated remotely
System on a chip (SOC)
Which is microprocessor or microcontroller with advanced peripherals such as WIFI. Closed loop component for embedded systems. Chips are inexpensive and profit margin slim. Little incentive to maintain/update firmware
Steppingstone
Embedded systems attack, embedded systems a HVAC systems, printers, and camera systems are often connected to a network and unmanaged
Embedded system
Is an electronic product that contains a microprocessor and software designed to perform a specific task. Can be fixed or programmable , network attack for this systems exploits the protocol of authentication
Memory BUS
Attack for embedded systems -physically connecting to the hardware and reading the content of memory
Weak authentication
Embedded systems attack, using default administrator passwords
