Healthcare Cybersecurity Essentials
Healthcare is among the most targeted sectors for ransomware, and practices are attacked precisely because downtime is intolerable. Here's the practical baseline.

Healthcare is targeted disproportionately for a simple reason: practices cannot tolerate downtime, which makes them unusually likely to pay. Small practices are not too small to be targeted. Most attacks are opportunistic and automated.
The controls that stop most attacks
- Multi-factor authentication on every remote access point, email account and administrative login
- Endpoint detection and response on every workstation and server, not just consumer antivirus
- Immutable, offline backups with restores tested on a schedule: not merely configured
- Email filtering with attachment sandboxing, since phishing remains the dominant entry vector
- Prompt patching of operating systems, EHR clients, browsers and VPN appliances
- Network segmentation isolating medical devices and guest Wi-Fi from clinical systems
Why backups fail when they matter
Most practices hit by ransomware have backups. The backups fail for predictable reasons: they were connected to the network and got encrypted too, they hadn't run in weeks, or nobody had ever attempted a restore and it didn't work.
Immutability solves the first problem. Monitoring solves the second. Only a tested restore solves the third, and a backup that has never been restored is a hypothesis, not a control.
Staff training that actually works
Annual compliance training does not change behavior. Simulated phishing with immediate, non-punitive feedback does, and click rates drop measurably within a few cycles.
Make reporting frictionless and reward it. A staff member who reports a suspicious email within minutes is worth more than any single technical control.
Plan the incident before it happens
Decide now who is called, in what order, and how you operate clinically without systems. Print the plan: if it only exists on the network, you won't have it when you need it.
Know your breach notification obligations and timelines in advance. The window is short, and it starts running while you're still trying to understand what happened.
