Traffic can be very finely controlled through access at the two firewalls, and services can be provided at multiple levels to both internal and external networks. In the next section, we profile some of the advantages and disadvantages of the common approaches to DMZ architecture and provide a checklist of sorts to help you to make a decision about the appropriate use (or not) of the DMZ for protection. 2 details the advantages and disadvantages of the various types of basic design discussed in the preceding section.

A DMZ is an optional and more secure approach to a firewall and effectively acts as a proxy server. Bastion host A machine (usually a server) located in the DMZ with strong (untrusted host) host-level protection and minimal services. It is used as a gateway between the inside and the outside of networks. The bastion host is normally not the firewall but a separate machine that will probably be sacrificial in the design and expected to be compromised. The notation “untrusted host” may be used because the bastion host is always considered to be potentially compromised and therefore should not be fully trusted by internal network clients.

Please note that each of these configurations is useful on internal networks needing protection as well as protecting your resources from networks such as the Internet. 4. This configuration would typically be used to begin to protect a small business or home network. This situation could include payroll, finance, or development divisions that need to 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.
