Describe your vision for addressing the security requirements in the overall technical design of the ABC Healthcare network. This should include both internal and external (untrusted and trusted) aspects. Untrusted would include user connectivity to the Internet. The "trusted" network has the main purpose of supporting the business functions of known entities (i.e. partners, suppliers, etc.) which have a business relationship with the company. Note you are to concentrate on the high level and are not expected to provide low level details for your recommended design.
