These projects are designed for beginners: if right now you just know the basics of Python syntax this is a perfect way to start applying that knowledge in a practical manner while learning more about how Python is used in cybersecurity. Please note that for most of the mini projects I'll be doing multiple videos in which we continue to build on the previous work to improve on them in a manner that helps us really better understand their logic. I also want to mention that these projects will not only be great for beginners to learn, but also to build a portfolio which can help you land a job in the industry. In the previous lesson we built a firewall simulator to starting thinking about the foundational logic underpinning a firewall. In today's lesson we'll build a Python script designed to monitor network traffic and detect potential Denial of Service attacks by analyzing the rate at which IP packets are sent. If the rate exceeds a predefined threshold which we can set, then the script will block the IP address, mitigating the impact of the attack. In this script I'll also introduce you to the Scapy library, a powerful network manipulation tool, to sniff and analyze network packets.
