1. Capturing Network Traffic: Definition & Processes
When talking about computers or the internet you must have heard the term network traffic. What exactly is network traffic? How can you monitor and filter it? In this lesson we will learn some of the basic concepts of network traffic.
2. What is a Network Scanner? - Definition & Use
The network scanner is an important element in the arsenal of the network administrator as well as the penetration tester. It allows the user to map the network and its topology as well as to find devices that would be hard to find manually. It allows a security analyst or penetration tester to find devices on the network that could be likely opportunities to use to begin a breach into the network. Let's explore this essential tool in some detail.
