Network Protocols for Security

IPv4 and ARP

Understanding how network protocols operate is an implied skill required to be successful in cyber security. In this course, we’ll practice creating network traffic and inspecting Link and Internet layer protocols.

Understanding how network protocols operate is an implied skill required to be successful in cyber security. In this course, Network Protocols for Security: IPv4 and ARP, you’ll learn to analyze IPv4 and ARP network traffic. First, you’ll explore MAC addresses and how they can be spoofed in a network. Next, you’ll discover the details of the ARP protocol. Finally, you’ll learn how to sift through a malicious IPv4 traffic example. When you’re finished with this course, you’ll have the skills and knowledge of IPv4 and ARP needed to find anomalies and malicious activity amongst network traffic
