Healthcare practices rely on outside vendors more than ever. EHR companies, imaging equipment manufacturers, billing services, lab interface providers, and IT support firms often need some way to reach your systems.

Remote access makes that support fast and convenient. It also creates one of the most overlooked security gaps in healthcare. When a vendor's connection is always on, poorly protected, or shared among many technicians, it becomes a door that attackers can use too.

Why Vendor Access Is a Real Risk

Several well-known healthcare breaches have started with a third party rather than the provider itself. Attackers know that one vendor may connect to dozens or hundreds of practices. Breaking into the vendor, or simply stealing a technician's password, can open many doors at once.

Common problems we find in small and mid-sized practices include:

• Remote access tools installed years ago and never removed.
• Vendor accounts with permanent administrator rights.
• One shared login used by every technician at the vendor.
• No record of when vendors connect or what they do.
• Vendors with access to far more systems than they support.

The HIPAA Connection

Vendors that create, receive, maintain, or transmit protected health information on your behalf are generally business associates under HIPAA. You need a business associate agreement (BAA) with them, and they have their own obligations to protect that information.

A BAA is important, but it's a legal document, not a technical control. It doesn't stop a stolen password from working. Practices still need to manage how and when vendors connect. Your HIPAA risk analysis should include vendor access as a specific area of review.

Five Ways to Close the Gap

1. Inventory every vendor connection

Start by listing every vendor that can reach your systems remotely. Include the tool they use, which systems they access, and who at your practice approved it. Many practices discover connections no one remembers setting up.

2. Give each technician an individual account

Shared vendor logins make it impossible to know who connected. Ask vendors to use named accounts for each technician, protected with multifactor authentication.

3. Turn access on only when needed

Many practices now use "just-in-time" access. The vendor requests a session, someone at the practice approves it, and the connection is closed when the work is done. Always-on access should be the rare exception.

4. Limit what vendors can reach

An imaging vendor needs access to the imaging system, not the entire network. This idea, called least privilege, is a core part of zero trust security.

5. Log and review sessions

Keep records of when vendors connect, how long they stay, and what systems they touch. Review them periodically, and investigate anything unexpected, such as a connection at 3 a.m. on a Sunday.

Questions to Ask Your Vendors

• Which remote access tool do you use, and how is it secured?
• Do your technicians use individual accounts with multifactor authentication?
• How do you protect your own systems from compromise?
• Will you notify us promptly if you have a security incident?
• Can access be enabled only when we approve a support session?

Vendors that take security seriously will welcome these questions.

A Vendor Access Review Checklist

• ☐ Current list of every vendor with remote access.
• ☐ Signed BAAs where vendors handle patient information.
• ☐ Individual vendor accounts with multifactor authentication.
• ☐ Access limited to the systems each vendor supports.
• ☐ Remote sessions approved and closed after use.
• ☐ Session logs retained and reviewed.
• ☐ Old or unused vendor tools removed.
• ☐ Vendor access reviewed at least annually.

A Brief Example

A dermatology practice discovered during a review that a former practice management vendor still had a remote access tool installed on the front-desk computer, three years after the practice switched systems. The tool had a saved password and could connect at any time. Removing it took fifteen minutes. Leaving it in place could have exposed the entire office.

Make Vendor Access Work for You

Vendors are partners in patient care, and they need reliable ways to help you. With the right controls, practices can keep that support fast while closing a major security gap.
