Design the layout of users, domains,
trusted domains, anonymous users, etc for a start-up open source software
company ABC. They should have an internal CVS server (only internal developers
can access it), an anonymous CVS server for outsiders to download source code,
a WWW server (one for internal and one for external) and an internal mail
server. It is crucial that outsiders should not be able to access either
internal CVS or internal WWW servers.

The design should be provide below requirements:

1. The topology diagram for the different

2. The assumptions that you make for
your design and the security policy to achieve this assumption.

3. Trust
assumptions about users (e.g., who could be root, what a root could do). You do
