If your company has gone through an ISO 13485 audit, a customer qualification review, or a formal ITGC assessment, you have probably encountered questions about access control. Role-based access. Privileged account management. Provisioning and deprovisioning processes.

Those terms are familiar. What is less clear, for most IT teams at SMB medical device companies, is exactly what auditors are looking for when they ask about them, and what kind of documentation actually satisfies the question.

What Auditors Mean by Access Control

When an auditor asks about access control in an ITGC review, they are asking several related
questions at once:

  • Do users have only the access they need to do their jobs, and is that access defined by role rather than by individual preference?
  • When someone joins the company, is access provisioned through a documented process,
    appropriate to their role from day one?
  • When someone leaves or changes roles, is their access removed or modified promptly and through a documented process?
  • Is someone periodically reviewing who has access to what, especially for privileged accounts, and is that review documented?

Note what is not in that list: specific technology requirements. Auditors are not looking for a particular identity management platform or a specific review cadence. They are looking for evidence that access is managed intentionally, consistently, and with documentation that proves it

The most common ITGC finding in medical device audits is not a missing control. It is an undocumented one that has been running the right way for years.

The Three Access Control Gaps Most Commonly Cited in ITGC Reviews

If you are doing a self-assessment before an FDA inspection, start with these three areas:

01

Departed employees with active credentials

This is the single most reliable finding in any access control review. People leave, access gets deprovisioned from the primary HR system, andsomething gets missed: a legacy application, a shared service account, a VPN credential set up
separately.

The fix is a formal offboarding checklist owned by IT and verified for every departure

02

Undocumented privileged access

Someone was given administrator rights on a system three years ago because it was convenient. There is no record of the approval, no periodic review, and no documentation of what that access allows.

Privileged account management does not have to be complex, but it has to be documented.

03

Shared accounts on manufacturing or lab equipment

Many instruments and manufacturing
systems were not designed with individual user accounts in mind. They run a single admin
credential shared among everyone who uses the equipment.

That is a legitimate constraint in
some cases, but it requires compensating controls and documentation to be defensible in an audit.

Mapping to NIST CSF and FDA Expectations

The NIST CSF Protect function includes Identity Management and Access Control as a core category. The outcome language is worth knowing: “Identities and credentials are issued, managed, verified, revoked, and audited for authorized devices, users, and processes.” That sentence is essentially a checklist for an access control program.

FDA’s data integrity guidance echoes these principles at the application level: access to systems that create or modify regulated records should be attributable to specific individuals, and that attribution should be reliable. IT controls are what make that reliability possible.

What Good Access Control Documentation Actually Looks Like

You do not need an enterprise IAM platform to have defensible access controls.

You need three things:

  • Documented process for granting access

  • Documented process for removing or modifying it

  • Periodic review that confirms the current access list matches

Those three things, done consistently with evidence, will satisfy the access control questions in most ITGC reviews at companies under 500 employees. The gap is almost never the controls themselves. It is the documentation that proves the controls are actually being executed.
