What it is

The Remote Access Zero-Trust Security Checklist is a downloadable, work-through audit of the controls that keep a remote-access deployment from becoming a breach. It is organized around the failure patterns that actually cause incidents: stolen technician credentials, over-broad standing access, and unmonitored unattended sessions. Rather than reciting zero-trust theory, it hands you a concrete list of gaps to close — enforce MFA on every technician, admin, and service account; federate logins through your identity provider over SAML or OIDC so there are no orphaned local passwords; provision and deprovision through SCIM so a departed technician loses access automatically; and require phishing-resistant factors (FIDO2/passkeys) wherever you can.

The checklist is grouped into four control domains — identity and authentication, least-privilege access, device trust and posture, and session monitoring and audit — so you can hand each section to the team that owns it and track progress. It applies whether you run a help-desk on ConnectWise Control, a server fleet on TeamViewer, or unattended access through Splashtop Business Access; the underlying controls are tool-agnostic. Used end to end, it turns 'we think remote access is locked down' into a documented, line-by-line attestation of what is and isn't in place.

It pairs naturally with the other remote-access resources in this collection: the endpoint posture checklist for the device-trust line items, the MFA rollout plan for the authentication domain, and the session audit template for proving the monitoring controls actually fire. Treat this checklist as the master index of your zero-trust hardening and the others as the deep dives.

What it's used for

Teams reach for this checklist whenever remote access has grown faster than the controls around it — typically when an MSP scales its technician base, when IT inherits an unattended-access fleet with no policy, or when a security review exposes how much standing access exists. It converts a vague worry into a prioritized punch list. The most common uses:

✓ Hardening a new remote-access or RMM deployment before it touches production, so the security baseline is set on day one rather than retrofitted after an incident.
✓ Auditing an existing TeamViewer, AnyDesk, or ConnectWise Control estate to find the gaps — SMS-only MFA, wide-open default groups, unrecorded privileged sessions — that quietly accumulated over time.
✓ Closing the three highest-risk patterns specifically: removing standing admin access in favor of just-in-time elevation, gating sessions on device posture, and recording connections to sensitive systems with tamper-evident storage.
✓ Preparing for SOC 2, ISO 27001, or a customer security questionnaire by mapping each control claim to a concrete, evidenced line item.
✓ Separating attended-support permissions from unattended-server permissions so a help-desk technician can't reach production servers they have no business touching.
✓ Driving a quarterly access review: disabling dormant accounts, demo logins, and any wide-open default groups, and confirming SCIM deprovisioning actually removes departed staff.
✓ Streaming connection, file-transfer, and admin-change logs into a SIEM so anomalous sessions are caught in real time rather than discovered after the fact.

Who uses it

The checklist is written for the people accountable for remote access security, but each of its four domains has a natural owner. In a small shop one person may run all four; in a larger org it splits cleanly across teams.

IT / infrastructure leadsThey own the remote-access tooling and the day-to-day decisions about groups, permissions, and unattended access, so the least-privilege and device-trust sections land squarely on their desk.

Security engineers and CISOsThey need an evidenced view of how remote access is controlled and use the checklist to drive the SIEM integration, session recording, and impossible-travel alerting that prove monitoring works.

MSP and help-desk managersTheir technicians connect to dozens of client environments daily; the checklist enforces MFA, scoped access, and recording so one compromised technician account doesn't cascade across clients.

Identity and access (IAM) administratorsThey implement the SAML/OIDC federation, SCIM provisioning, and phishing-resistant MFA that the identity domain calls for.

Compliance and audit teamsThey use the completed checklist as the control narrative behind SOC 2 or ISO 27001 evidence requests, mapping each line to a tested control.

vCISOs and security consultantsThey run the checklist as a rapid maturity assessment across client environments, producing a prioritized remediation list in a single engagement.

Context & good to know

Remote access is now one of the most reliable ways into an organization. The pattern repeats across breach reports: an attacker phishes or buys a technician's credential, logs into the remote-access console, and inherits exactly the access that technician had — often standing admin rights to a wide swath of endpoints. Zero trust is the answer not as a product but as a posture: never assume a session is safe because it authenticated once, and never grant more reach than the task needs. This checklist operationalizes that posture into controls you can actually turn on.

The reason a checklist beats good intentions is that remote-access security fails in boring, specific ways — an MFA policy with an SMS opt-out, a 'default' group everyone landed in, a session-recording setting that was never enabled on the servers that mattered. None of these are sophisticated; all of them are invisible until someone enumerates them. Working line by line surfaces the gaps that a high-level 'is remote access secure?' conversation always misses.

Tooling matters here because capabilities differ. TeamViewer, ConnectWise Control, Splashtop Business Access, Zoho Assist, and VNC Connect each support these controls to varying degrees — some have native session recording and SIEM streaming, others lean on your IdP for MFA and federation. When buyers compare remote-access software, the real differentiator past the demo is which of these zero-trust controls are built in versus bolted on. Use the checklist to score candidates as well as to harden what you already run.

Finally, this is a living document. Access drifts — new technicians, new servers, new vendors — and a control that was true last quarter quietly isn't anymore. The strongest teams re-run the checklist on a fixed cadence and after every significant change, treating it as a recurring review rather than a one-time project.

FAQ

Questions, answered

What does zero trust actually mean for remote access?

It means dropping the assumption that an authenticated session is a safe session. Every connection is verified continuously on identity (who, with MFA), device (is the endpoint healthy and posture-compliant), and scope (only the systems the role authorizes — nothing more). Standing admin access is replaced with just-in-time elevation, sessions to sensitive systems are recorded, and access is removed automatically when someone leaves. The checklist breaks this into concrete, enable-able controls.

What is the single highest-impact control on the checklist?

For most teams it's eliminating standing privileged access in favor of just-in-time elevation, closely followed by phishing-resistant MFA on every account. Over-privilege is what turns one hijacked session into a major incident; removing it limits the blast radius when, not if, a credential is compromised. MFA is what stops the credential from being usable in the first place.

What is the best remote access software for a zero-trust setup?

There's no single best tool — it depends on whether you need attended support, unattended server access, or both, and on your compliance needs. The right way to choose is to score candidates against zero-trust controls: native MFA/SSO federation, granular role-and-group scoping, device-posture gating, and tamper-evident session recording. TeamViewer, ConnectWise Control, Splashtop Business Access, and Zoho Assist all support large parts of this; the checklist gives you the scorecard to compare them on what matters.

Is SMS MFA good enough for technician accounts?

No. SMS is vulnerable to SIM-swap and interception, and technician accounts are exactly the high-value targets attackers go after. The checklist calls for phishing-resistant MFA — FIDO2 security keys or passkeys, or at minimum authenticator push with number-matching — for any account that can reach sensitive systems. Keep SMS only as a last-resort fallback for low-privilege users.

How does device posture fit into the checklist?

Posture gating means a session can't start unless the originating device meets a health bar — disk encryption on, OS patched within SLA, EDR present and healthy, MDM-compliant. It stops a compromised or out-of-date laptop from becoming the door into production even when the credentials are valid. The companion endpoint posture checklist details exactly which signals to require per device class.

Do I really need to record remote sessions?

For privileged and production targets, yes. Recording is the only reliable after-the-fact account of what actually happened in a session — it's the first thing an auditor or incident responder asks for, and it protects honest technicians by showing what they did and didn't do. Store recordings in tamper-evident, immutable storage and retain them per your compliance schedule.

How is unattended access different from attended, and why does it matter here?

Attended access requires a person at the remote machine to grant the session; unattended access connects to servers, kiosks, and machines with no one present. Unattended access is a top ransomware entry point precisely because there's no human to notice. The checklist insists you separate the two permission sets so help-desk technicians can't silently reach unattended servers, and that unattended consent and notification meet whatever your regulation requires.

How often should we re-run this checklist?

At minimum quarterly, and after any material change — a new technician cohort, a new server fleet, a tooling migration, or a new vendor relationship. Access drifts constantly, so a control verified last quarter may not hold today. Pair the recurring review with SCIM-driven deprovisioning and a standing group-membership audit so the gaps are caught automatically between manual passes.

Can a small team realistically implement all of this?

Yes, but stage it. Start with the identity domain — MFA everywhere and federation through your IdP — because it closes the most common attack path fastest. Then tackle least-privilege scoping, then device posture, then full session recording and SIEM streaming. The checklist is ordered so the highest-leverage controls come first, which lets a small team make meaningful progress without a big-bang project.
