Every cybersecurity incident starts with a motivated attacker trying to achieve his goals by attacking a target. The motive can be money, power, fame, or even a desire for revenge. The target can be a person, a company, an organization, or even a country.

In today’s world, where almost every electronic device is connected to the Internet Network, this network became one of the most common ways of performing the attack.

Infecting a computer with malware which usually happens throughout the network, and controlling that target computer is not the goal of the attack but a phase towards the final.

Moreover, the attacker will usually want to extract information from the infected computer. How can he extract this information? Through the same network which he used to attack the computer.

Therefore, the network plays a significant role in cyber-attacks, and with Network Forensics, one can learn about how the attack was started, what kind of information was leaked out and what is the attacker’s motive.

In this lesson, we will meet some network concepts, protocols, and tools that will help us with our investigation. We will also look at a demonstration of a network attack and show how we can investigate it using some existing tools.
