# Welcome to week 2

Welcome back! I'm so glad you're joining us.

Previously, you were introduced to incident detection and response.

You may also remember learning about networking from a previous course.

To recap, you learned about how devices talk to each other using network protocols and

the different types of network attacks.

You also examined some network security best practices.

Here, we'll expand on networking and shift our focus to network analysis.

First, you'll examine

network communications by

exploring network traffic flows.

Next, you'll learn about viewing and

capturing network traffic using packet sniffers.

Then, you'll be introduced to packet analysis,

where you'll examine packet fields and decode

communication between devices and networks.

As a security professional,

you'll be tasked with monitoring networks and

system infrastructure to detect malicious activities.

And this section will provide you with the opportunity to

develop your network and packet analysis skills.

Are you ready to begin? Let's get started!
