Recommended network architecture for BlackBerry SWS

This example was designed on the base of the diagram from the "BYOD Guidance: BlackBerry Secure Work Space" on the website of the UK Communications Electronics Security Group (CESG).
"Secure Work Space (SWS) for iOS and Android is a containerisation, application-wrapping and secure connectivity option that delivers a higher level of control and security to iOS and Android devices, all managed through the BlackBerry Enterprise Service (BES) administration console.
Work space applications are secured and separated from personal applications and data. The work space applications include an integrated email, calendar, and contacts application, an enterprise-level secure browser, and a secure document viewing and editing application.
The work browser allows users to securely browse the organisation’s intranet and the Internet. If the device is lost or the employee leaves the organisation, you can chose to delete only corporate information or all information from the device.

Recommended network architecture
The walled garden architecture, shown below, aims to limit the impact of a compromise of an EUD and isolate high risk components from high value components where possible. The enterprise servers installed as part of SWS are high value resources that require suitable protection but are also high risk; they perform complex processing tasks that are more likely to contain exploitable vulnerabilities. These competing priorities make securely placing the servers into an existing network challenging, and organisations that wish to deviate from this architecture below should ensure they understand the risks of doing so."
