Why Hospitals Need Network Access Control: Four Practical Benefits

Hospital networks connect clinical equipment, medical-record systems, staff workstations, and the personal devices of patients and visitors. Protecting sensitive information while keeping care services available requires a clear understanding of what is connected and which connections are necessary. Network Access Control (NAC) can support this work through device visibility and network access policies.

1. Identify medical devices and plan network segmentation

Connected equipment can include infusion pumps, patient monitors, and imaging systems. Some devices have long service lives or restrictions on software updates and agent installation. Their network access needs to reflect their clinical function and manufacturer requirements.

Genian NAC uses network sensors and Device Platform Intelligence to help discover and classify devices. Identification depends on the information available and the platform database; unfamiliar equipment may require manual validation. IT teams can use the resulting inventory to group devices and plan access restrictions with compatible network infrastructure.

For example, a device group may need access to a designated clinical server while having no operational reason to reach administrative workstations. Validate those communication paths with the clinical engineering team and equipment supplier before enforcing restrictions. Segmentation can reduce unnecessary exposure, but it does not repair vulnerabilities in a medical device.

2. Restrict network access to systems holding patient information

Medical records contain sensitive health and identity information. Limiting which users and devices can connect to the networks serving those systems adds a useful layer of protection.

Genian NAC supports authentication and access policies based on user and device context. On supported staff endpoints, configured posture checks can also inform access decisions. The controls available depend on the selected edition, endpoint support, enforcement method, and integrations.

Permissions to view or change an individual patient record must still be enforced by the medical-record application. NAC complements application authorization, encryption, endpoint protection, and other security measures; it cannot by itself guarantee that data leaks or ransomware incidents will be prevented.

3. Separate patient and visitor Wi-Fi from clinical operations

Doctors, nurses, administrators, contractors, patients, and visitors have different connectivity needs. A visitor’s phone should not receive the same network access as an approved clinical workstation.

Genian NAC supports guest onboarding and policies based on authenticated users or device groups. Together with compatible switches, wireless infrastructure, and firewalls, these policies can help separate public Wi-Fi from clinical and administrative networks. Staff access can be aligned with job requirements, while temporary access follows an approval process.

Confirm the enforcement design and test permitted and prohibited connections across wired and wireless networks. A separate Wi-Fi name alone is insufficient to establish effective isolation.

4. Support audit evidence and privacy governance

Indonesia’s Personal Data Protection Law, Law No. 27 of 2022, classifies health data and information as specific personal data. Hospitals need to assess their applicable privacy and security obligations as part of wider information governance.

Genian NAC device records and network access logs can help IT teams review connected assets and investigate access events. Their usefulness depends on monitoring coverage, authentication, logging configuration, and retention. Network logs should be considered alongside application audit trails when investigating access to medical records.

These records can support security reviews and compliance work, but installing NAC does not establish legal compliance. Access to the logs and their retention should also follow the hospital’s privacy and information-security policies.

Evaluate Genian NAC with PT ELUON

Begin with a visibility assessment and a limited proof of concept. Agree on device classification, necessary clinical communications, exception handling, and a recovery procedure with IT, clinical engineering, and relevant suppliers. Review active discovery and enforcement methods before enabling them on sensitive equipment, then introduce controls in stages.
