The physical infrastructure environment is hosted at FRII (Front Range Internet). The network components and supporting network infrastructure are contained within the servers hosted at FRII. The LifeWIRE environment consists of SonicWall firewalls; IIS web servers; .Net application servers; SQL Server database servers; Windows Server virtual machines; and developer tool servers running on Windows Server and Windows 10 machines.
Within the LifeWIRE Platform on FRII, all data transmission is SSL encrypted and all hard drives are encrypted so data at rest is also encrypted; this applies to all servers - those hosting Docker containers, databases, APIs, log servers, etc. LifeWIRE assumes all data may contain ePHI, even though our Risk Assessment does not indicate this is the case, and provides appropriate protections based on that assumption.
In the case of PaaS Customers, it is the responsibility of the Customer to restrict, secure, and assure the privacy of all ePHI data at the Application Level, as this is not under the control or purview of LifeWIRE.
- Within FRII, hosted load balancers segment data and traffic while Sonicwall firewalls route traffic to private subnets for LifeWIRE Customers and for Platform Add-ons.
- Within FRII, hosted load balancers segment data across dedicated Virtual Private Clouds for LifeWIRE and for Platform Add-ons.
The segmentation strategies employed by LifeWIRE effectively create RFC 1918, or dedicated, private segmented and separated networks and IP spaces, for each PaaS Customer and for Platform Add-ons.
Additionally, IP tables is used on each server for logical segmentation. IP tables is configured to restrict access to only justified ports and protocols. LifeWIRE has implemented strict logical access controls so that only authorized personnel are given access to the internal management servers. The environment is configured so that data is transmitted from the load balancers to the application servers over an TLS encrypted session.
In the case of Platform Add-ons, once the data is received from the application server, a series of Application Programming Interface (API) calls is made to the database servers where the ePHI resides. The ePHI is encrypted and stored in SQL Server databases through programming logic built, so that access to the database server without the encryption key will not present you with the full ePHI spectrum.
The VPN server and application servers are externally facing and accessible via the Internet. The database servers, where the ePHI resides, are located on the internal LifeWIRE network and can only be accessed over a VPN connection. Access to the internal database is restricted to a limited number of personnel and strictly controlled to only those personnel with a business-justified reason. Remote access to internal servers is not accessible except through load balancers.
All Platform Add-ons and operating systems are tested end-to-end for usability, security, and impact prior to deployment to production.
