Why Characterization Is Important

Characterization is important because it arms the administrator with valuable knowledge about the system. After completing characterization, an administrator knows all of the following:

  • Expected changes in files and directories and the operating system

  • Expected processes, when they are run and by whom, and what resources they consume

  • Expected network traffic consumed and produced

  • Expected hardware inventory on the system

The following sections explain step by step how to perform characterization for your system.
