Scapy is a powerful Python library used for network packet manipulation and analysis. It allows users to create, manipulate, send, and capture network packets. Scapy is particularly useful for network security professionals, developers, and researchers who need to interact with and analyze network traffic. Python Scapy empowers you to automate various cybersecurity tasks, both offensive and defensive. This course will teach you how to use Python and Scapy to build a port, honeypot, and custom vulnerability scanner. You’ll start with a brief introduction to Scapy, then learn how to monitor network traffic, create valid responses to incoming packets, and develop simple servers with automated responses. You’ll also interact with an API and develop a port and vulnerability scanner. By the end of this course, you should be familiar with Scapy and capable of working with network packets in Python.
