Zero Trust Network Architecture Quiz

1. Which technology enables secure remote access aligned with zero trust principles?

Traditional VPN

Software-defined perimeter (SDP)

Unrestricted remote access

Public Wi-Fi networks

2. Which security principle is essential for zero trust implementation?

Trust but verify

Never trust, always verify

Verify once, trust forever

Trust all authenticated users indefinitely

3. How does zero trust architecture address cloud and hybrid environments?

It is incompatible with cloud services

It applies verification and segmentation regardless of infrastructure location

It only works for on-premises networks

It requires separate security models for each environment

4. What is the primary challenge in implementing zero trust architecture?

High cost of network hardware

Complexity of managing continuous verification across all resources

Lack of security standards

Insufficient encryption algorithms

5. Which framework aligns with zero trust security model principles?

NIST Cybersecurity Framework

ISO 27001 only

COBIT governance

SOC 2 compliance alone

6. In zero trust, what does 'verify the device' mean?

Check the device owner's identity

Assess device security posture before granting access

Verify the device manufacturer

Confirm device location only

7. Which principle requires regular review and revocation of access rights?

Defense in depth

Continuous access evaluation and least privilege

Network segmentation

Encryption standards

8. What is the role of logging and auditing in zero trust infrastructure?

Record access for compliance only

Provide visibility and forensic analysis of all activities

Monitor external threats only

Generate monthly reports for management

9. How does zero trust architecture handle insider threats?

It assumes insiders are always trusted

It monitors and verifies all user actions regardless of role

It only monitors external access

It relies on background checks only

10. In zero trust architecture, what is the significance of encryption?

Used only for external communications

Applied to all data in transit and at rest

Optional for internal network traffic

Implemented only at the perimeter

11. What is the fundamental principle of zero trust architecture?

Trust all internal traffic by default

Never trust, always verify every access request

Perimeter security is sufficient protection

Implement trust after initial authentication only

12. What is the primary benefit of implementing microsegmentation in infrastructure?

Reduces bandwidth usage

Limits lateral movement of threats within the network

Eliminates the need for firewalls

Improves network speed

13. Which security model requires authentication for every access attempt, even within the network?

Perimeter-based security

Zero trust model

DMZ protection

Air-gapped networks

14. In secure infrastructure design, what does device posture assessment evaluate?

Physical location of the device

Security status including patches, encryption, and compliance

Device manufacturer only

User's job title

15. What role does multi-factor authentication (MFA) play in zero trust architecture?

Optional security measure for sensitive data

Essential for verifying user identity continuously

Used only for remote access

Replaces the need for strong passwords

16. Which of the following is a key characteristic of the least privilege principle?

Grant maximum permissions to all users

Users receive only permissions necessary for their role

Permissions are permanent once granted

Administrators have unrestricted access

17. What is the primary purpose of identity and access management (IAM) in zero trust?

Store passwords securely

Verify and authorize every user and device access request

Manage only administrative accounts

Control network bandwidth allocation

18. Which access control model is most compatible with zero trust principles?

Role-based access control (RBAC)

Discretionary access control (DAC)

Attribute-based access control (ABAC)

Mandatory access control (MAC) only

19. In zero trust, what does continuous monitoring primarily focus on?

Only external threats

User behavior and device posture in real time

Perimeter intrusions only

Quarterly compliance audits

20. Which component divides a network into smaller zones to enforce access controls?
