The demonstration intends to illustrate how Trusted Network Connect (TNC) Open |
Source tools of multiple vendors can be combined to smartly address the complex scenario |
of securing a Bring Your Own Device (BYOD) scenario. The example scenario integrates |
the strongSwan!| VPN solution, developed by the University of Applied Sciences in Rap- |
perswil (Switzerland), with several iron*?|tools by the Trust@HsH research group at the |
University of Applied Sciences and Arts in Hanover (Germany), and the Android-IF-MAP- |
Client] by DECOIT GmbH, a SME company from Bremen (Germany). The combination |
of those tools allows to implement a network security solution which responds to security |
incidents in near real-time. The scenario is set in a Bring Your Own Device (BYOD) |
environment where employees use their own smartphones for enterprise tasks. Different |
TNC IF-MAP tools are combined to enforce corporate policies affecting the employees’ An- |
droid cell phone devices on initial network connection and to continuously monitor policy |
conformity if behavioral changes of the devices occur. |
1 Scenario Overview |
The scenario for the demonstration is shown in figure [1] The strongSwan VPN gateway enables |
external devices, such as the smartphone, to access the internal corporate network. In terms of |
Trusted Network Connect (TNC) the strongSwan VPN gateway acts as Policy Enforcement Point |
