A new connection changes more than a network diagram. It changes who can reach a resource, from which device, under whose authority, and with what evidence when something goes wrong. Start with a short, shared baseline before adding the next route in.
Begin with the resource, not the connection.
Name the application, data, or service being accessed. Identify the business owner, the technical owner, the approved users, and the reason access is needed. “Remote access” is not a complete requirement; “a contractor needs one project application for the duration of an engagement” is a useful starting point.
NIST’s zero-trust architecture guidance treats authentication and authorization as decisions around resources, rather than assuming trust from network location alone. A practical access review should reflect that distinction.
Give every identity an owner.
Review employee, administrative, vendor, and service accounts. Look for shared credentials, dormant access, excessive permissions, and accounts whose business purpose is no longer clear. Keep privileged access distinguishable from ordinary daily work.
Check the authentication requirements and the handling of exceptions. Multifactor authentication, account lifecycle processes, and access reviews need an owner as well as a technical setting.
Understand the device and the route.
Decide which devices may connect, who maintains them, and what configuration or vulnerability information is available. Then trace the route to the target resource. Does the connection expose additional services that the user does not need?
Document the required paths and boundaries. The result should be understandable to the team that approves access and the team that implements it.
Plan for detection and revocation.
Identify where access events are recorded and who can investigate them. Confirm how an account, session, or third-party route can be disabled, and which service owner makes that decision.
Connect recovery arrangements to the service in question. A generic incident document is less useful than a named contact, an agreed revocation method, and a tested understanding of the affected system.
Make the decision reviewable.
Create a short record of the scope, owner, evidence checked, exceptions, approval decision, and next review date. Unknowns should create follow-up work; they should not disappear into a general statement that the connection is “secure.”
This baseline is a practical planning aid within a wider security program. Its value is in turning assumptions into explicit decisions.
Bring it into the conversation
A practical checklist.
- Can we name the resource owner and approved users?
- Are privileged and vendor accounts individually owned?
- Have authentication, permissions, and device requirements been reviewed?
- Can the team see and investigate access events?
- Can someone revoke the connection promptly?
- Do exceptions have an owner and a review date?
