Which cybersecurity model emphasizes continuous verification and strict access controls for every request?

• A. Zero Trust
• B. ECN
• C. APC
• D. COOP

Answer: (A)

Continuous verification for every access attempt with strict, identity-based access controls defines Zero Trust. In this approach you don’t trust anyone or anything by where they’re located on the network; every request must be authenticated and authorized before access is granted, regardless of whether it comes from inside or outside the perimeter. Decisions are made per transaction, based on who is requesting access, the security posture of the device, the specific application, and the current risk context. Access is limited to the least privileges needed, often enforced through practices like MFA, device health checks, micro-segmentation, and continuous monitoring. Because trust is never presumed and is continually reassessed, potential lateral movement after a breach is more easily contained and detected. This contrasts with traditional perimeter-based security, which implicitly trusts users or devices once they’re inside the network, and with concepts that focus on continuity or other domains rather than per-request access control.
