Summary
In this chapter, we talked about network protocols – from Ethernet and MAC addresses, through ARPs and IP addresses, to higher layers with TCP and UDP, talking about potential attacks against them, how to generate attacks, and how to protect against them. We learned how to generate ping attacks, TCP SYN, and various flag attacks, how to discover them when they happen, and how to protect against them, and we finished with TCP hijacking attacks – how they are implemented and how to protect against them.
In the next chapters, we will start to get into the details of various network operations and application protocols, starting with wireless networks.
