Most successful attacks exploit known weaknesses for which a fix already exists. The updates that close those weaknesses are called patches, and applying them promptly is one of the least glamorous and most effective security habits. In a facility that operates around the clock, though, patching has a real tension. Nobody wants a computer to restart in the middle of a medication pass.
The answer is not to skip patches. It is to plan them around how the building actually works.
Staff postpone restarts because they are busy
Nobody owns the process
Some devices, such as older medical equipment, cannot be updated easily
Past updates caused problems, so people fear them
There is no visibility into which machines are missing updates
Each reason has a practical response.
You cannot patch what you do not know exists. Maintain a list of computers, servers, network equipment, printers and medical or IoT devices, along with operating systems and software versions. Anything that no longer receives vendor updates should be flagged for replacement or isolation.
Not everything needs the same treatment.
These are the highest priority. Apply critical security updates quickly, within days of release when possible, after a brief check.
Schedule maintenance windows, usually late at night or on a low-activity weekend, with advance notice to clinical leadership and a rollback plan.
Use automated management tools to download updates in the background, then restart at a scheduled time. Many tools let you set active hours and allow a limited postponement before a restart is required.
Stagger restarts so that a unit never loses all its computers at once, and avoid shift changes and medication passes. Some facilities designate a mid-morning window or a quiet overnight period.
Coordinate with the manufacturer. Some require vendor-approved updates. Where patching is not possible, segment the device from the rest of the network and monitor it.
Many organizations follow a cycle roughly like this:
Week 1: Review released updates and decide which are urgent.
Week 1 to 2: Test on a small pilot group, such as IT and a few willing users.
Week 2 to 3: Roll out to the wider organization during agreed windows.
Week 4: Verify, chase exceptions and report.
Emergency vulnerabilities that are being actively exploited, which agencies like CISA list in a catalog of known exploited vulnerabilities, deserve an accelerated path.
Post plain notices: what is happening, when, and what to do if something goes wrong. Give nurses a way to ask for a delay in a real emergency. Appoint a clinical contact who can approve or reschedule windows.
Report on compliance. How many machines are fully updated? Which have not checked in for weeks? Devices that are off or missing from the network are often the ones that slip. Review exceptions and note reasons.
Operating system updates are only part of it. Web browsers, PDF readers, remote support tools, printer drivers and firmware on switches and firewalls all need attention. Tools that automate third-party updates reduce effort significantly.
Keep backups before major updates, record which update caused trouble if one does, and be able to remove it quickly. A brief test with your EHR client and printers on pilot machines catches many issues.
A short patch management policy, along with logs showing updates were applied, supports your HIPAA Security Rule documentation and often helps with cyber insurance applications.
UnityCare IT manages patching for healthcare clients, scheduling around clinical routines and reporting on exceptions. If your updates depend on whoever remembers to click a button, we can help replace that with a steady, predictable process.
