CS – C844 ITAS 3040 Emerging Technologies in
Cybersecurity
Comprehensive Objective Assessment (Qns &
Ans)
2025
Question 1 (Multiple Choice)
Question:
Which emerging technology is primarily known for securing data
transactions using a decentralized ledger, thereby enhancing data
integrity?
A) Quantum Key Distribution
B) Blockchain
C) Homomorphic Encryption
D) Intrusion Detection Systems
Correct ANS:
©2025
,B) Blockchain
Rationale:
Blockchain technology leverages a distributed ledger to ensure
that data is stored across multiple nodes, making it resistant to
tampering and revision. Its decentralized nature and cryptographic
security make it a key technology for ensuring data integrity in
emerging cybersecurity solutions.

Question 2 (Fill in the Blank)
Question:
________ is increasingly being employed in cybersecurity to
automatically process large volumes of data and detect anomalies
that may indicate novel cyber threats.
Correct ANS:
Machine Learning
Rationale:
Machine learning algorithms excel at recognizing patterns in
complex datasets. In cybersecurity, they help in identifying

,unusual behavior that might signal an emerging threat, thereby
providing proactive defense mechanisms.
---
Question 3 (True/False)
Question:
Quantum computing poses a potential threat to many widely-
adopted encryption standards due to its ability to factor large
numbers exponentially faster than classical computers.
Correct ANS:
True
Rationale:
Quantum algorithms, such as Shor’s algorithm, can break
traditional encryption schemes (for example, RSA) by efficiently
factoring large numbers. This potential capability underscores the
importance of developing quantum-resistant cryptographic
methods.

, Question 4 (Multiple Response)
Question:
Select all emerging technologies that contribute to strengthening a
Zero Trust architecture in cybersecurity environments:
A) Microsegmentation
B) Behavioral Analytics
C) Blockchain-based Identity Management
D) Traditional Perimeter Firewalls
Correct ANS:
A, B, C
Rationale:
Zero Trust architectures rely on principles such as continuous
verification and segmentation. Microsegmentation limits lateral
movement within networks; behavioral analytics ensures
continuous monitoring of user and device behavior, and
blockchain-based identity management offers decentralized,
tamper-resistant authentication. Traditional perimeter firewalls,
by contrast, are based on an outdated trust model.
