Checklist for Inventorying and Prioritizing Access Accounts in a SME

Managing access is not just about choosing secure passwords; it involves knowing who has an account, how they prove their identity, what they can do, and how to remove their access when their relationship with the company changes.

For an SME, starting with these questions allows you to order controls without confusing them with a general application inventory or a vendor assessment.

The goal is to turn identity and access management—known as IAM—into a process that covers the entire lifecycle of each account: onboarding, permission changes, reviews, and offboarding. This checklist serves as an operational guide; it does not replace a risk assessment nor determine regulatory compliance on its own.

1. Identify accounts and assign owners

Before deciding who needs access, compile an inventory of existing identities and accounts. Don’t limit yourself to employees: also include contractors, suppliers, and other external persons with system access.

For each account, record at least:

• Associated person or identity and their relationship with the company.
• System or service accessed.
• Account function and permission level.
• Internal owner who authorizes or reviews that access.
• Status: active, temporary, or pending removal.

Linking accounts to a person or identity helps locate orphaned accounts—those without a clear owner—and prevents accesses from surviving a role change or contract end. If there are shared accounts, note who uses them and who is responsible; when feasible, prioritize individual accounts to improve traceability.

2. Prioritize accounts that can open the most doors

Not all accounts require the same review order. Start with those controlling other accesses or enabling entry to sensitive information and systems:

• Administration of systems, devices, networks, or cloud platforms.
• Email, which can be involved in password resets and document access.
• Finance, due to access to operations and financial data.
• Remote access and cloud storage.
• Accounts with access to sensitive data or security tools and backups.

Priority is a way to order work, not a guarantee that other accounts are risk-free. Include also vendor and contractor identities, and verify whether their access remains necessary and who within the company sponsors it.

3. Verify how each identity authenticates

Authentication verifies that the person logging in is who they claim to be. For high-impact accounts, enable multi‑factor authentication (MFA) whenever the service allows. Sources particularly highlight email, administrative accounts, remote access, finance, and cloud or sensitive data resources.

The inventory should record which authentication method protects each account and flag critical accounts that still lack MFA. This lets the company identify concrete gaps and prioritize their remediation. MFA strengthens verification but does not replace permission review or offboarding processes.

4. Review what each account can do

Authorization defines what actions a person can perform once inside. Check whether permissions match current tasks and remove those no longer needed. Applying the principle of least privilege means granting only the access necessary for work, rather than keeping broad permissions for convenience.

When roles and responsibilities allow, role‑based access control (RBAC) helps assign permissions based on defined functions. Verify that roles reflect real responsibilities and review exceptions: a job change, a temporary task, or a project may justify an adjustment but not necessarily permanent permission.

Pay special attention to privileged accounts. Record who can use them, for which systems, and with what justification; avoid those rights being tied to people who no longer perform the corresponding function. If a task only requires elevated privileges for a limited period, consider temporary access when company systems and processes allow it.

5. Establish a process for onboarding, change, and offboarding

A point‑in‑time access control loses effectiveness if not updated when people or their functions change. Define who communicates and who executes each step in these situations:

1. Onboarding: authorize the account and necessary permissions for the role.
2. Change: review accesses when someone changes roles, takes on other tasks, or leaves a project.
3. Offboarding: deactivate or remove accounts when the employment or contractual relationship ends, revoking access that no longer applies.

Include third‑party accounts and active sessions when relevant. Responsibilities and specific timelines will depend on each company’s operations; available sources do not set a universal deadline for executing offboardings.

6. Schedule reviews and maintain traceability

Assign someone to periodically review the inventory and confirm that accounts, permissions, and owners remain correct. Frequency can be defined based on access criticality and company capacity but must specify when reviews occur and who resolves discrepancies.

Keep records of onboarding, modifications, approvals, and offboardings, plus system activity logs. That traceability allows reconstruction of who had access and what changes were made. It can also facilitate audits and support management of applicable requirements, though maintaining records or implementing IAM does not by itself prove compliance with a standard.

Operational checklist

• An inventory of accounts linked to people or identities exists.
• Each account has an associated system and internal owner.
• Administrative, email, finance, remote access, and sensitive data accounts are identified.
• The authentication method protecting each critical account is known.
• MFA is enabled for priority accounts when the service permits.
• Permissions match current functions and are limited to what’s necessary.
• Privileged accounts have a designated owner and justified use.
• A process exists for onboarding, role or task changes, and offboarding of employees and third parties.
• Accounts, permissions, and vendor accesses are reviewed periodically.
• Sufficient records exist to identify changes and owners.

A continuous process, not a one‑off cleanup

Access management functions as a chain: identity, authentication, authorization, and revocation. If any part is neglected, orphaned accounts, excessive permissions, or unnecessary accesses can persist. For an SME, an inventory with owners, clear priorities, and periodic reviews provides a practical foundation to keep that cycle under control.

Standards and frameworks such as NIS2 and ISO 27001 may include requirements related to security and access management. Their concrete application depends on scope, entity, and relevant requirements; this checklist is not a legal interpretation nor a compliance statement.
