Abstract:
1. A computer-implemented method for providing security to a network client device, comprising: receiving, by the network client device, one or more DHCP Offer responses to a request for network configuration information; determining, by the network client device, a score associated with each DHCP Offer response of the one or more DHCP Offer responses, the score indicative of trustworthiness of the DHCP Offer response, wherein determining the score associated with each DHCP Offer response comprises assigning a first score for the DHCP Offer response based on an attribute included in the DHCP Offer response related to a DHCP server address and assigning a second, lower score for the DHCP Offer response based an attribute included in the DHCP Offer response related to a client IP address, and wherein the trustworthiness of the DHCP Offer response indicates a likelihood that the DHCP Offer response originates from a trusted source; selecting, by the network client device, a DHCP Offer response from the one or more DHCP Offer responses based at least in part on the scores respectively associated with the one or more DHCP Offer responses; and configuring the network client device according to the selected DHCP Offer response.
