Exercise 1 - Denial of Service

There are any number of ways to prevent a server from responding to clients. We could have used Ettercap to simply discard any packets from client or server for instance.

This exercise just illustrates how simple it is to craft the sort of malformed packets that can be used to try to flood a server.

Exercise 2- Anti-Phishing Toolbar

In this exercise, you will learn the following in this course:

• Anti-Phishing Toolbar: Netcraft
