IoT & Emerging Technologies Flashcards

What cybersecurity framework specifically addresses IoT device security requirements in the US?

Answer: NIST IR 8259

NIST IR 8259 provides a baseline of cybersecurity activities for IoT device manufacturers to improve the security of their products sold in the US market.

Which emerging technology uses distributed ledger to enable automated, self-executing contracts?

Answer: Smart contracts on blockchain

Smart contracts are self-executing programs stored on a blockchain that automatically enforce agreement terms when predefined conditions are met.

What is quantum key distribution (QKD) used for?

Answer: Securely exchanging encryption keys using quantum mechanics principles

QKD uses quantum physics properties to exchange cryptographic keys in a way that detects any eavesdropping attempt, providing theoretically unbreakable key exchange.

What does 'zero-trust' mean when applied to IoT network architecture?

Answer: Requiring continuous verification of every device regardless of network location

Zero-trust IoT architecture treats every device as untrusted by default, requiring continuous authentication and least-privilege access regardless of whether the device is inside the network.

Which AI technique enables IoT devices to collaboratively train a model without sharing raw data?

Answer: Federated learning

Federated learning trains a shared model across distributed devices by exchanging model updates rather than raw data, preserving privacy on each device.

What is the primary security risk of using unsegmented flat networks for IoT devices?

Answer: Compromised IoT devices can laterally move to attack critical corporate systems

Without network segmentation, a compromised IoT device has unrestricted access to the same network as servers and workstations, enabling lateral movement attacks.
