Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Defense in depth
Why it's wrong here
Defense in depth relies on layered static controls—firewalls, antivirus, and segmentation—to slow an attacker, but it lacks the dynamic, per-request evaluation of context, device posture, and identity required by the zero-trust principle of never trusting by default. It is tempting because its layered approach is often conflated with zero trust’s “never trust, always verify” philosophy; in a scenario requiring resilience against multi-vector attacks rather than continuous authentication, defense in depth would be the correct choice.
- ✗
CIA triad
Why it's wrong here
CIA triad is a model for confidentiality, integrity, and availability.
- ✗
Least privilege
Why it's wrong here
Least privilege is a principle, not a full security model.
- ✓
Zero Trust
Why this is correct
Zero Trust is based on 'never trust, always verify' and least privilege.
