This situation could include payroll, finance, or development divisions that must protect their information and keep it away from general network use and view. 5 details a protection design that would allow for the implementation and provision of services outside the protected network. In this design, it would be absolutely imperative that rules be enacted to not allow the untrusted host to access the internal network. Security of the bastion host machine would be accomplished on the machine itself, and only minimal and absolutely necessary services would be enabled or installed on that machine.

9 reviews the traffic flow in a network containing a bastion host and a single firewall. This network configuration does not produce a DMZ; the protection of the bastion host is configured individually on the host and requires extreme care in setup. Inbound traffic from the untrusted network or the bastion host is dropped at the firewall, providing protection to the internal network. Outbound traffic from the internal network is allowed. 10 shows the patterns of traffic as we implement a D M Z design.

A r m e d with this information, you can proceed to mitigate the known risks and weak points within your D M Z . As we continue with our overview of D M Z design principles, we also need to discuss the management of resources and the challenges that occur in designing for administration and control of the D M Z . The following sections detail a number of the areas that we must be aware of during our consideration of design and D M Z implementation. Application Servers in the DMZ Application server placement in the D M Z must be designed with tight controls in mind.
