DHCP Spoofing Attack and Mitigation in Cisco Packet Tracer

 In this Cisco Packet Tracer tutorial, you will learn exactly how a DHCP Spoofing Attack works and how to configure DHCP Mitigation using DHCP Snooping on a Cisco switch. This step-by-step network security lab is perfect for CCNA candidates, IT students, and system administrators looking to defend their local networks against rogue DHCP servers.

Learn how a DHCP spoofing attack functions by simulating a network breach in Cisco Packet Tracer. See how traffic is intercepted. This tutorial demonstrates the mechanics of a rogue DHCP server within a controlled environment. Designed for network students and security enthusiasts, this walkthrough explains how malicious actors manipulate IP address assignments to redirect client traffic. You will observe the step-by-step configuration required to set up both a legitimate and a rogue server to understand the vulnerability. By building this network security lab, you gain practical experience in identifying how unauthorized servers compromise network integrity. The process clarifies the relationship between DHCP requests and server responses, providing a clear visual representation of how traffic interception occurs in a local network segment. Understanding DHCP spoofing is essential for building more resilient network defenses and recognizing potential misconfigurations in your own infrastructure. Subscribe for weekly network security breakdowns, and comment which other Cisco Packet Tracer labs you want to see next. We will simulate a rogue DHCP server hijacking client IP addresses, analyze the packet behavior, and then use the Cisco CLI to completely block the attack.
