DoS Design Considerations

Applied Knowledge Questions

The following questions are designed to test your knowledge of general network security design considerations, 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.

1:

What would the inbound ACL look like on your router's serial interface connected to the Internet if you decided to block RFC 1918 addresses, the bogons listed in this chapter, and RFC 2827 filtering, assuming your local IP range is 96.0.20.0/24?

2:

When evaluating the SYN flood protections required for a server, when might you use SYN cookies and when might you use TCP Intercept?

3:

What is the most important step when you are trying to get help from your ISP to stop a DDoS attack?

4:

When might it not be necessary to implement L2 security features on your network?

5:

Should the average user worry about van Eck phreaking?

6:

When should you use uRPF as compared to traditional ACL filtering?

7:

Is it worth implementing Rob Thomas's entire bogon-filtering range on your Internet edge?
