Sniffing Technique : DHCP Attacks
This section discusses the DHCP attacks. A DHCP attack is an active sniffing technique used by the attackers to steal and manipulate sensitive data. This section describes how DHCP works, DHCP starvation attacks, tools used for starvation attacks, rogue server attacks, and the ways to defend against DHCP attacks. How DHCP Works Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that gives an IP address to an IP host. additionally to the IP address, the DHCP server also provides configuration-related information like the default gateway and subnet mask. When a DHCP client device boots up, it participates in traffic broadcasting. DHCP can assign IP configuration to hosts connecting to a network. The distribution of IP configuration to hosts simplifies the administrator's work to take care of IP networks. DHCP servers maintain TCP/IP configuration information during a database like valid TCP/IP configuration parameters, valid IP addresses, and durat...
