Essential Skills for Hackers is about the skills you need to be in the elite hacker family. The book will mainly about two things: TCP/IP 101, and Protocol Analysis. The better the hacker, the more we will be able to master TCP/IP. Once the reader understands what TCP/IP is, what it looks like, the book will go into Protocol Analysis and how analyzing the protocol or, in a more general sense, looking at packets on the wire, we will be able to determine what exactly is taking place on a network. By doing this, readers can identify when something on the network doesn’t match what it should and, more importantly, can create any type of sequence of events or packets that they want on the network and see how the defenses or the machines that we send them to react. Presents an foundation for the skills required to be an elite hacker.
