Knowing what goes on over a network requires a high-level picture of it. The ability to conceptualize your network's structure, capabilities, and events is essential to protecting it. In this course, you'll explore the concepts and tools required to identify and visualize your network components.
You'll work mostly with the open source network protocol analyzer, Wireshark. You'll start by displaying protocol hierarchies and identifying network endpoints. You'll then describe considerations for visualizing networks and create a network diagram using Visio.
Next, you'll outline network security assessment methods, recognize the use of baselines for network management, and carry out baseline activity monitoring. You'll also look at ways of capturing network data. Lastly, you'll explore how Wireshark combines with other tools such as Nmap, SSH, and firewalls.
