Securing Connected Diagnostic Equipment in Eye Care Practices
Diagnostic equipment like OCT scanners, fundus cameras, and auto-refractors is now part of the connected network in eye care practices, storing and transmitting patient data making it essential to include in the practice’s cybersecurity strategy.
The Challenge:
These devices are built for clinical accuracy, not security. Many run outdated operating systems since updates can risk disrupting FDA-cleared functionality. Devices often stay in use for 8-10 years, while manufacturer security support ends much earlier. They frequently share flat networks with EHR systems, scheduling software, and guest Wi-Fi, making it easier for an attacker to move from one compromised device toward patient records. Unmonitored vendor remote access adds another entry point.
How Attacks Happen:
Attackers typically gain an initial foothold through a weak point phishing, an unpatched device, or a compromised vendor session. From there, they move laterally across the network toward imaging systems and patient data, eventually exfiltrating records, deploying ransomware, or in advanced cases, interfering with device functionality itself.
A Practical Framework:
- Segment diagnostic devices onto their own VLAN
- Maintain a complete, up-to-date device inventory
- Apply patches and firmware updates on a defined schedule
- Govern vendor remote access with time-limited, monitored sessions
- Use compensating controls (segmentation, access restrictions, monitoring) for legacy devices that can’t be patched
- Monitor for unusual network behavior
- Include diagnostic devices in HIPAA Security Rule risk assessments
Why It Matters Beyond Compliance:
This isn’t just about avoiding penalties compromised devices can delay diagnoses, cancel appointments, and disrupt daily operations.
How ICSI Helps:
ICSI provides eye care practices with network segmentation, device inventory and risk assessment, vendor access governance, ongoing monitoring, and HIPAA alignment all designed around clinical uptime needs, without interrupting patient care.
Key Stats:
53% of connected medical devices have an unpatched critical vulnerability; devices average 6+ known vulnerabilities each; 60% of devices in use are end-of-life; in 2026, 1 in 5 healthcare organizations were hit by an attack involving a medical device.
