Third Party Access Management in a Device Business

A medical device business is unusually dependent on outside specialists. Contract manufacturers need visibility of orders and specifications. Equipment vendors need remote access to service machines. Software suppliers need access to diagnose problems. Regulatory consultants need documents.

All of that is legitimate. The problem is what happens to the access afterwards.

Why third party access management is harder than employee access

When an employee leaves, a process runs. Human resources tells identity management. Accounts get disabled. It is not perfect and it mostly works, because there is an owner and a trigger.

Vendors have neither. A contract ends and nobody informs identity management, because nobody thinks of it as their job. The engineer who set up the remote access has moved on. The account stays live, holding the same privileges it had when it was needed.

Most businesses that run their first review are surprised by what they find. Not because anyone was careless, but because there was no moment where removal was anybody responsibility.

Standing access is the thing to attack

The single highest value change is moving from access that always exists to access granted when it is needed and removed afterwards.

The practical version is not exotic. A vendor requests access for a task. It is approved by somebody who knows why it is needed. It is granted for a bounded period. The session is recorded. It expires on its own rather than needing somebody to remember.

That converts a permanent exposure into a short one. It also produces a natural record of who accessed what and why, which is exactly the evidence you will want later.

Our guide to privileged access implementation covers how this gets rolled out in a first ninety days without stopping the business.

Shared accounts break attribution

Vendor access is often set up as one account used by whoever is on shift at the supplier. It is convenient and it destroys attribution.

If three engineers share a login, your logs record the account rather than the person. You cannot answer who made a change. In a business where the ability to show who did what is part of your regulatory standing, that gap is worse than it first appears.

The fix is individual identity for each person, even where the underlying privilege is shared. Where the vendor cannot support that, a managed session that records the human on one side and brokers the privileged account on the other gets you attribution without asking them to change how they work.

Machine identities count too

Not all third party access is a human logging in. Integrations, monitoring agents and data feeds all hold credentials, and those credentials tend to be older and less reviewed than any human account.

They are also the ones most likely to hold broad permissions, because the quickest way to make an integration work is to give it more access than it needs and move on. Nobody comes back to narrow it.

Treat these as accounts with owners and review dates. Our guide to machine identity and secrets management covers the mechanics.

Connected devices change the shape of the problem

A device business often has two distinct security conversations. One is about corporate systems. The other is about devices in the field that connect to networks you do not control.

They are genuinely different problems and they get confused because both are called security. Keep them separate in your planning. Corporate access governance and product security have different stakeholders, different expertise and different regulators.

What they share is a dependence on knowing what exists. An inventory that is partly accurate is the root of most findings in both areas.

Start with the list

You cannot govern access you cannot enumerate. So the first piece of work is a list of every third party with access, what they can reach, who approved it and when it was last reviewed.

Build it from two directions. From your contracts, which tell you who should have access. And from your systems, which tell you who does. The gap between those two lists is the finding, and it is usually large enough to justify the exercise on its own.

Then set a review cycle with a named owner per relationship. Reviews without an owner do not happen. Our risk assessment guide covers how to prioritise once you can see the full picture.

What this protects

The obvious answer is data. The more important answer in this sector is evidence.

Your ability to show that records were changed by authorised people, following an approved process, is part of what makes your quality system credible. Access that cannot be attributed weakens that, quietly, across every record the account touched.

That is why access governance in a device business is not only an IT concern. It is part of the same argument as your traceability and your change control.

Where to go next

TechCloudPro works on third party access management through privileged access and machine identity for medical device businesses and for healthcare organisations facing the same third party exposure. If you do not currently have a single list of who outside your business can reach your systems, that is the first thing worth building.
