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.

In the context of IoT, why is predictive analytics important?

  • To achieve real-time data visualization
  • To enhance physical device durability
  • To proactively identify issues and optimize performance
  • To transmit data to the cloud for storage
Predictive analytics in the context of IoT is essential because it allows organizations to proactively identify issues and optimize the performance of IoT devices and systems. By analyzing historical data and patterns, predictive analytics can help prevent problems before they occur, leading to more efficient operations.

________ keys are cryptographic keys that can be used for both encryption and decryption in symmetric cryptography, commonly used in IoT devices.

  • Private
  • Public
  • Session
  • Shared
Shared keys, often referred to as symmetric keys, are used in symmetric cryptography. These keys are shared between the sender and receiver, allowing them to both encrypt and decrypt data, making them a common choice for IoT devices.

A company's smart thermostat was remotely accessed and its settings were maliciously changed. This is an example of:

  • Cyber Attack
  • Cybersecurity Vulnerability
  • Data Breach
  • Unauthorized Access
This scenario represents a Cyber Attack where a malicious entity remotely accessed the thermostat to make unauthorized changes. It's a clear instance of a deliberate attack rather than just an unauthorized access or a vulnerability.

One of the best practices for IoT device provisioning is ensuring devices have unique ________ to prevent cloning.

  • "Device Names"
  • "Firmware Versions"
  • "MAC Addresses"
  • "Serial Numbers"
One of the best practices for IoT device provisioning is ensuring devices have unique "Serial Numbers" to prevent cloning. Each IoT device should have a distinct serial number to prevent unauthorized duplication or replication of devices, which can help maintain the integrity and security of the IoT ecosystem.

An IoT device that is susceptible to a man-in-the-middle attack is lacking in:

  • Encryption
  • Identity Verification
  • Secure Communication Protocols
  • Strong Authentication
When an IoT device lacks secure communication protocols, it becomes vulnerable to man-in-the-middle attacks, where an attacker intercepts and potentially alters the communication between two parties. Strong authentication, encryption, and identity verification are important, but without secure communication, these measures can be compromised.

In an agricultural setup, a farmer wants to monitor the soil moisture, temperature, and pest activity across large fields. The most suitable technology to deploy would be:

  • Bluetooth Technology
  • Drones
  • Satellite Imagery
  • Wireless Sensor Networks
Wireless Sensor Networks are the most suitable technology for monitoring soil conditions and pest activity across large fields. They offer a cost-effective and efficient way to collect data from various points in the field. Satellite imagery, drones, and Bluetooth technology have their uses in agriculture but may not be as suitable for this specific purpose.
