This chapter provides a very brief introduction to TCP/IP protocol for readers not familiar with the concepts of TCP/IP.[1] We then go on to discuss the advantages and disadvantages of implementing security at various layers in the stack. This is necessary to understand the reasons to implement security at various layers. This also provides the framework to discuss IP security in the following chapters.
[1] For a more in-depth discussion of TCP/IP protocol, we strongly recommend that readers refer to other books.
