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.
Is a VPN sufficient? / Incomplete decision
Inspect an incomplete decision based on record existence or another positive signal. Consider denial cases alongside permitted use.
s => s.vpnEnabled === trueA VPN indicator establishes no individual identity, MFA evidence or local sponsorship. Without these links, who accessed which process remains unclear; complete the access review.

01 / EXPLANATION
Own the access need
A Harbor vendor requests remote maintenance support. Define the target asset, business purpose, individual identity and duration. Trusting a supplier company does not authorize every employee for every system. The local sponsor owns process context and maintenance readiness. Shared accounts make review harder; associate individual identity with access records. The policy also addresses contracts, third-party lifecycle, departing personnel and ended services. This exercise supplies no real connection address or credentials. A complete request supports review but does not itself establish that the requested session should be opened.
02 / EXPLANATION
Jump path and session boundary
Enterprise identity, strong authentication, a controlled jump point and target-specific authorization complement each other. A VPN alone limits neither targets nor onward movement. Harbor records the access window, target list, permitted work, session oversight and closure check separately. The authorized team defines recording and retention under applicable policy; indefinite collection of every screen is not a default answer. Network reachability does not grant application or process-command authority. Actual session establishment and termination procedures are outside this local model. Review the entire chain rather than one gateway indicator.
03 / EXPLANATION
Govern emergency access too
An emergency label does not remove local authorization. If the normal channel fails, use a previously designed emergency-access process with an authority owner, alternative communications and retrospective review. Consider how revocation affects process support; automatic disconnection is not universally safe. In Harbor, learners seek an owner, duration, impact review and revocation/review plan. The model opens and ends no real session. Relevant operating and safety authorities determine what action is appropriate at a real site, including dependencies that a generic identity workflow cannot know.
04 / EXPLANATION
Use a reference architecture appropriately
NIST SP 1800-45 provides remote-access examples for water and wastewater utilities. Those examples are not pre-approved designs for another factory. Evaluate the supported identity technology, latency and availability needs, vendor constraints and local operating model. Harbor workpapers separate architectural assumptions, available evidence and missing validation. Access reviews include contract and role-change triggers alongside periodic review. The result identifies which access was reviewed, by whom and with what evidence, instead of assigning a generic secure label. References support discussion; site-specific decisions still require appropriate owners.
