What is DHCP in Cybersecurity?
Dynamic Host Configuration Protocol automatically assigns IP addresses, subnet masks, gateways, and DNS servers to devices joining a network. A DHCP server leases addresses from a defined pool, reducing manual configuration and preventing address conflicts across large networks.
Why DHCP Matters for Your Cybersecurity Career
Rogue DHCP servers are a common attack vector. An attacker can set up a fake DHCP server to redirect traffic through their machine for interception. Security engineers must understand DHCP snooping and how to detect unauthorized DHCP responses on a network.
