| 500 | Admin | IT administration | WPA2/WPA3-Enterprise with MFA |
Configure VLAN assignment in IronWiFi using RADIUS reply attributes. See Attributes for details.
HIPAA Compliance Considerations
HIPAA Security Rule Requirements
The HIPAA Security Rule requires technical safeguards for protecting electronic Protected Health Information (ePHI). IronWiFi helps meet these requirements:
| HIPAA Requirement | Section | IronWiFi Implementation |
|---|---|---|
| Access Control | §164.312(a)(1) | Unique user authentication via RADIUS; role-based VLAN assignment |
| Audit Controls | §164.312(b) | RADIUS authentication and accounting logs with configurable retention |
| Integrity | §164.312(c)(1) | Message authenticator on RADIUS packets; certificate-based auth |
| Person Authentication | §164.312(d) | Individual credentials (username/password, certificates, or IdP) |
| Transmission Security | §164.312(e)(1) | EAP-TLS encrypted tunnels; RadSec for transport encryption |
Network Segmentation for ePHI
Isolate networks that carry ePHI from general-purpose networks:
- Clinical VLAN -- Only authorized clinical staff on this VLAN
- Firewall rules -- Clinical VLAN can reach EHR systems; Patient VLAN cannot
- Access logging -- All authentication to the clinical VLAN is logged with user identity
- Session limits -- Clinical sessions time out after shift duration (e.g., 8 hours)
Network segmentation alone does not satisfy HIPAA. It is one layer of a defense-in-depth strategy that must include endpoint security, data encryption, access controls, and administrative safeguards.
Audit Trail Configuration
Configure RADIUS accounting to maintain a complete audit trail:
- Navigate to Networks > select the clinical network
- Ensure RADIUS accounting is enabled on your access points
- Set the accounting interim interval:
Reply Attribute: Acct-Interim-Interval := 300
- Configure data retention for at least 6 years (HIPAA record retention requirement)
- Export logs regularly to your organization's SIEM or archival system
See Data Governance and Compliance for retention configuration.
Business Associate Agreement
If IronWiFi processes or stores data adjacent to ePHI in your deployment, a Business Associate Agreement (BAA) may be required. Contact IronWiFi to discuss your specific deployment and execute a BAA if applicable.
Clinical Staff WiFi
Authentication Options
| Method | Security Level | User Experience | Best For |
|---|---|---|---|
| EAP-TLS (Certificates) | Highest | Seamless (no password prompts) | Managed devices |
| PEAP-MSCHAPv2 | High | Username/password on first connect | Mixed environments |
| SAML via Captive Portal | High | Single sign-on with existing IdP | Organizations with Azure AD/Okta |
Certificate-Based Authentication for Staff
For the highest security, deploy EAP-TLS with client certificates to clinical staff devices:
- Configure SCEP in IronWiFi for automated certificate issuance
- Push WiFi profiles to managed devices via your MDM (Intune, Jamf, etc.)
- Certificates authenticate the device without password prompts
- Revoke certificates instantly when a device is lost or an employee departs
See Certificate Lifecycle Management for implementation details.
Integration with Healthcare Identity Providers
Connect IronWiFi to your existing identity infrastructure:
- Azure AD / Entra ID -- SAML authentication for staff using Microsoft credentials
- Okta -- SAML authentication for organizations using Okta
- Active Directory -- LDAP connector for on-premises AD authentication
- Google Workspace -- Google authentication for organizations using Google
Configure connectors in the IronWiFi Console under Users > Connectors. See Connectors for setup guides.
Staff Roaming Across Campus
Healthcare facilities often span multiple buildings. Ensure seamless roaming:
- Use the same IronWiFi Network across all access points on campus
- Enable 802.11r (Fast BSS Transition) on your APs for sub-50ms roaming
- Enable 802.11k (Neighbor Reports) to help devices make better roaming decisions
- Set appropriate session timeouts (shift length) to avoid mid-shift re-authentication
- Configure both primary and secondary RADIUS servers for redundancy
Medical Device Networks
Challenges with Medical Devices
Medical and biomedical devices present unique authentication challenges:
- Many devices only support basic authentication or no 802.1X at all
- Firmware updates may be infrequent or unavailable
- Devices may not support WPA2-Enterprise
- Device lifecycles are long (10--20 years for some equipment)
MAC Authentication for Medical Devices
For devices that cannot perform 802.1X authentication, use MAC address authentication:
-
Register the device's MAC address in IronWiFi:
- Navigate to Users > Create User
- Set the Username to the MAC address (format: )
aa-bb-cc-dd-ee-ff - Set the Password to the same MAC address
- Add the user to the Medical Device group
-
Configure your access points for MAC authentication bypass (MAB)
-
The device connects, the AP sends the MAC address as credentials, and IronWiFi authenticates it against the registered entry
MAC authentication is less secure than certificate-based authentication because MAC addresses can be spoofed. Mitigate this risk by placing MAC-authenticated devices on a dedicated VLAN with strict firewall rules.
Device Registration Workflow
Establish a process for registering new medical devices:
- Request -- Biomedical engineering submits a device registration request with MAC address, device type, and clinical purpose
- Approve -- Network security reviews and approves the request
- Register -- IT registers the MAC address in IronWiFi and assigns it to the appropriate group
- Test -- Verify the device connects and receives the correct VLAN
- Document -- Record the device in the asset management system
Monitoring Medical Device Connectivity
Use IronWiFi's logging to monitor medical device network access:
- Navigate to Logs > Authentication Logs
- Filter by the Medical Device group
- Look for unexpected authentication failures or unusual patterns
- Set up alerts for critical devices (e.g., infusion pumps, patient monitors)
Patient and Visitor WiFi
Captive Portal Configuration
Provide a user-friendly WiFi experience for patients and visitors:
- Navigate to Captive Portals > Create Portal
- Configure the portal for the Patient/Visitor network:
| Setting | Recommended Value |
|---|---|
| Authentication | Accept Terms of Service (no credentials required) |
| Terms of Service | Include acceptable use policy and HIPAA notice |
| Session Duration | 24 hours (auto-reconnect for multi-day stays) |
| Bandwidth Limit | 10 Mbps down / 5 Mbps up per user |
| Welcome Message | Hospital name, support contact info |
- Customize the branding with the healthcare facility's logo and colors
- Test the portal experience on iOS, Android, and laptop devices
HIPAA Notice on Patient WiFi
Include a clear notice on the captive portal that:
- The guest WiFi network is not encrypted end-to-end
- Users should not transmit sensitive health information over this network
- The facility is not responsible for data transmitted over the guest network
- Usage is subject to the acceptable use policy
Limiting Patient WiFi Access
Ensure the patient network cannot reach clinical systems:
- Assign patient connections to the Patient VLAN (300)
- Configure firewall rules to allow only internet access from VLAN 300
- Block access to clinical VLANs (100, 200), internal servers, and management interfaces
- Apply bandwidth limits to prevent streaming from impacting clinical traffic
IoT and Biomedical Device Management
Categorizing Healthcare IoT Devices
| Category | Examples | Risk Level | Recommended VLAN |
|---|---|---|---|
| Clinical IoT | Infusion pumps, patient monitors, smart beds | Critical | MedDevice (200) |
| Facility IoT | HVAC sensors, lighting controls, badge readers | Medium | Facility (separate VLAN) |
| Patient IoT | Personal health devices, wearables | Low | Patient (300) |
Network Policies for IoT
Apply restrictive policies to IoT devices:
- Bandwidth limits -- IoT devices typically need minimal bandwidth
- Session persistence -- Long session timeouts for devices that should stay connected
- No internet access -- Many clinical IoT devices only need to reach internal servers
- Monitoring -- Alert on unusual traffic patterns from IoT devices
