Digital investigators have an increasing need to examine data network logs and traffic, either as part of criminal or civil investigations or when responding to information security incidents. To truly understand the contents of the logs and the data packets, examiners need to have a good foundation in the protocols comprising the Transmission Control Protocol/Internet Protocol (TCP/IP) suite. This paper introduces the use of protocol analyzers and packet sniffers for TCP/IP traffic, and provides examples of normal and suspect TCP/IP traffic. This paper also provides a basis for a discussion of intrusion detection and signature analysis.
