Specialized System Security

Question 1

System-on-a-Chip (SoC)

Answer 1

Integrates all necessary electronic components into a single chip, requiring security to be embedded at the hardware level to protect against physical and cyber threats

Question 2

Embedded Systems

Answer 2

Designed to perform specific functions within larger devices and must be securely configured to prevent unauthorized access and ensure reliable operation

Question 3

Radio Frequency (RF)

Answer 3

One of the most commonly used wireless technologies, RF signals transmit data through electromagnetic waves over a range of frequencies

Question 4

Zigbee

Answer 4

Wireless technology that uses a higher frequency of 2.4 GHz, which allows for faster data transfer and supports more devices, making it good for bigger systems
Can face interference from devices

Question 5

Z-Wave

Answer 5

Wireless technology that uses a lower frequency around 900 MHz, giving better range and the ability to go through walls, making it more reliable in larger homes or buildings
Less likely to face interference

Question 6

Segmentation

Answer 6

Divides a network into smaller, isolated segments to limit the spread of attacks and reduce the exposure of critical systems to unauthorized access

Question 7

VLAN

Answer 7

Virtual Local Area Network
Allow different devices on the same physical network to be logically separated into different segments at layer 2 of the OSI model, limiting how they communicate with each other

Question 8

Aggregation

Answer 8

Refers to the process of collecting and combining data from various sources to create a single comprehensive dataset that can be analyzed for patterns, trends, or anomalies

Question 9

SCADA

Answer 9

Designed for remote monitoring and control of infrastructure across wide areas, making them ideal for managing multiple facilities.
