Welcome to Wireshark for Security Professionals. This introductory chapter covers three broad topics. In the first part, we discuss what Wireshark is used for and when to use it.

The second part of this chapter introduces the popular graphic user interface (GUI). The GUI for Wireshark can appear quite busy at first, so we immediately want to get familiar with its layout. We break down the different areas of the interface, how they relate to one another, and the reasoning for needing each one. We also discuss how and when each part of the interface helps you maximize your use of Wireshark.

In the third part of this chapter, we discuss the way Wireshark filters data presented on the interface. Being familiar with Wireshark's interface helps you appreciate all the data presented, but the amount of data can still be overpowering. Wireshark offers ways to filter or separate what you need from all that is presented. The last part is about different types of filters and how you can customize these filters.

Wireshark can appear to be a complicated tool, but by the end of this first chapter, the hope is you have a much higher comfort level with the tool's purpose, interface, and ability to present you with what you want to see.
