After a series of unauthorized data breaches from its IoT devices, a company decided to implement a system where each device had to present a unique digital certificate to communicate. This approach emphasizes:
- Data Encryption
- Data Storage
- Firewall Protection
- Identity and Authentication
Requiring unique digital certificates for each device emphasizes Identity and Authentication. It ensures that each device is who it claims to be, adding a layer of security to prevent unauthorized access or data breaches.
Which protocol is designed for scenarios where minimal code footprint is required and the network's bandwidth is limited?
- CoAP
- HTTP
- MQTT
- REST
The Constrained Application Protocol (CoAP) is specifically designed for IoT scenarios where resources, code footprint, and bandwidth are limited. It's a lightweight protocol that enables efficient communication between IoT devices and applications. CoAP is designed for constrained networks and devices.
To automate the process of inventory management, many retail stores have started using ________.
- Barcodes
- Drones
- GPS
- RFID
Many retail stores have adopted Radio-Frequency Identification (RFID) technology to automate and improve inventory management. RFID tags are attached to products, making it easier to track, manage, and update inventory in real time.
To ensure device integrity in the IoT landscape, manufacturers often employ ________ mechanisms.
- Authentication
- Authorization
- Data Mining
- Encryption
Manufacturers employ "Encryption" mechanisms to ensure device integrity in the IoT landscape. Encryption helps secure data and communication, preventing unauthorized access and tampering.
Why is data deduplication critical in IoT data storage?
- Enhancing data security
- Minimizing latency
- Optimizing data integrity
- Reducing storage costs
Data deduplication in IoT data storage is critical for reducing storage costs. IoT generates vast amounts of data, and much of it can be redundant. Deduplication identifies and eliminates duplicate data, conserving storage space and reducing operational expenses.
The delegation of access rights to various users in an IoT system is an example of:
- Access Control
- Data Encryption
- Device Authentication
- Secure Boot
The delegation of access rights to various users in an IoT system exemplifies access control. This ensures that users have appropriate permissions to interact with devices or data. Device authentication is related but distinct, and data encryption and secure boot are different security aspects.
Two-factor authentication in IoT devices helps to:
- Decrease device connectivity
- Enhance security
- Improve battery life
- Reduce data storage
Two-factor authentication (2FA) is a security measure that enhances security by requiring users to provide two different authentication factors before accessing a device or system. It significantly improves security by adding an extra layer of protection beyond just a password or PIN.
An organization is planning to deploy thousands of IoT sensors across a city for monitoring environmental conditions. To ensure data integrity and trustworthiness from all these sensors, they are considering:
- End-to-End Encryption
- Regular Sensor Calibration
- Secure Boot
- Secure Data Centers
Implementing a secure boot process is essential to ensure data integrity and trustworthiness from IoT sensors. It verifies the integrity of the sensor's firmware and prevents unauthorized or tampered code from running. End-to-End Encryption helps protect data in transit but doesn't ensure the integrity of the sensor's software. Sensor calibration and secure data centers are important but don't directly address sensor firmware integrity.
The concept of ________ allowed devices to collect and exchange data, leading to the birth of IoT.
- "Data Networking"
- "Internet of People"
- "Internet of Things"
- "Machine Learning"
The concept of the "Internet of Things" (IoT) allowed devices to collect and exchange data. IoT refers to the network of interconnected devices that communicate and share data, enabling various applications and automation. It has revolutionized industries by connecting physical objects to the internet, leading to greater efficiency and convenience.
When discussing privacy in IoT, the primary concern revolves around:
- Data ownership and consent
- Device compatibility
- Hardware specifications
- Network speed and latency
Privacy in IoT is primarily concerned with data ownership and consent. IoT devices collect a wide range of personal and sensitive data, and it's essential to address who owns this data, how it's used, and obtaining consent from users for data collection and processing.
