Network traffic analysis at the packet level is critical to diagnosing problems, solving performance issues, identifying security breaches and analyzing application behavior. In this session we will review the basics of TCP/IP, demonstrate how to take packet traces on platforms from mainframe to mobile and how to interpret the data. Sample cases involving OSA, DHCP, DNS, FTP, AT-TLS, suspect traffic, and network intrusions will be discussed.
