DESIGNING A SECURE NETWORK SOLUTION AGAINST DHCP ATTACKS

Abstract

DHCP is an important aspect in small and large networks, since it facilitates the IP configuration of computers. However, DHCP is vulnerable to different attacks; therefore, the essential objective of this paper is to propose solutions against DHCP attacks. The paper gives an explanation about how DHCP works and understand the handshake mechanism and give a brief summary about DHCP attack, how they occur and how they affect the security of the enterprise since a leakage of sensitive Information could happen, which threatens the enterprise's security or a denial of service that immobilizes the network. Three effective countermeasures are looked up and tested against DHCP attacks, and each one successfully prevented the attack.
