The Dynamic Host Configuration Protocol (DHCP) is the backbone of automated network onboarding, but its stateless nature makes it a prime target for disruption and manipulation. This beginner-friendly module breaks down the mechanics of the DORA (Discover, Offer, Request, Acknowledge) process, scope management, and lease allocation. You will learn how attackers exploit DHCP using rogue servers to perform Man-in-the-Middle (MITM) attacks or launch starvation Denial of Service (DoS) attacks. Finally, you will implement critical defensive controls like DHCP Snooping and IP Source Guard to secure your network's automated provisioning.
