Network Security Device Best Practices

Applied Knowledge Questions

The following questions are designed to test your knowledge of network security deployment options and best deployment practices, and they sometimes build on knowledge found elsewhere in the book. You might find that each question has more than one possible answer. The answers provided in Appendix B are intended to reinforce concepts that you can apply in your own networking environment.


Assume you are adding a NIDS to a three-interface firewall design. If you have budget for only one sensor, where should it go?


Assume the same design as the previous question, but now you have budget for two NIDS sensors. Where do you put them?


Your boss has asked you to select a device to provide connectivity to 50 branch offices. Each branch office requires VPN connectivity, routing, firewalling, and an IDS. Budget and manageability are key concerns. Which device, or devices, should you recommend?


Which future technology might make using NIDS to stop attacks more viable?


When might you want to have more than one public services segment on your Internet edge?


What is the most important component of any security technology deployed on an open source, noncommercially supported platform?
