Denial of Service Attack on a DNS

By: Daniel Perry IV and Joseph Rouleau
The objective of this project is to see if it is possible to crash a DNS server from an end node and how to prevent the attack. We will set up a DNS server and initiate a denial of service attack. The objective is to overwhelm the DNS server thus hindering any DNS services on the network. Because ICMP echo messages are a useful tool for troubleshooting connection issues, it is imperative to maintain ICMP capabilities within the local network. In order to maintain our need for local ICMP echo messaging while preventing ICMP attacks coming from the outside we will configure a screening router to allow ICMP messages from inside the local network and block ICMP echo messages from outside the local network. This will be done by use of an access control list.
