EVIDENCE REVIEW DESK
Move from observations to decisions.
Code here is a local policy model with no target connection. Passing model cases are not security approval or device tests.
Trusted because it is on the VPN? / Incomplete decision
Inspect an incomplete decision based on record existence or another positive signal. Consider denial cases alongside permitted use.
s => s.vpnConnected === trueNetwork connectivity establishes no identity, device or resource-policy assurance. Assess context for the resource decision; Boolean flags are not actual device or network validation.

01 / EXPLANATION
Zero Trust is not a product label
NIST SP 800-207 describes resource-focused trust decisions; presence on an enterprise network alone supplies no trust. Design decision and enforcement points using identity, device, resource and relevant context. A VPN may be one safeguard but does not authorize every resource. Harbor uses device context as a declared evidence field, not an actual health check. This lesson delivers no complete Zero Trust architecture, maturity rating or certification. Learners explain which resource and risk a decision addresses instead of treating a purchased product or network location as universal assurance.
02 / EXPLANATION
The boundary that enforces the decision
A policy engine’s deny does not end access if the target never enforces it. Assess signal sources, decision latency, error behavior and audit records together. Do not assume every system supports continuous immediate revocation. Harbor’s desk computes a fixed-time file-based decision; it is not a live enforcement point. Authorized owners assess operational effects of restrictions on critical work. Scoped negative tests can provide stronger boundary evidence than demonstrations of the successful path alone. The model does not contact a provider or alter an application policy.
03 / EXPLANATION
Scope and authority during identity incidents
For suspicious access, examine user and workload identities, consent, tokens and application sessions separately. Password changes or a central block alone do not close the incident. Authorized responders plan business effects, evidence and target-outcome verification. Record provider-specific revocation delays and ownership of application sessions. Harbor ends no actual sessions and creates no incident record. Learners separate supported observations from hypotheses and explain why establishing new credentials does not necessarily terminate old access. Response scope must follow the affected trust paths rather than one successful central action.
04 / EXPLANATION
Measure improvement through control evidence
A dashboard or blocked-sign-in count does not alone demonstrate coverage and correctness. Show included applications, excluded paths and what negative tests establish. Harbor links control ownership, resource inventory, decision design and outcome testing. Track exceptions through expiry and accountability. Success means necessary work remains bounded and traceable, not indiscriminate automatic blocking. Exercises on this page write no account points, exam results or credentials. Actual competency assessment and organizational assurance require separate evidence beyond correct answers in an educational model.
