A Framework for DNS Based Detection of Botnets at the ISP Level

- Description: The rapid expansion of networks and increase in internet connected devices has lead to a large number of hosts susceptible to virus infec-tion. Infected hosts are controlled by attackers and form so called bot-nets. These botnets are used to steal data, mask malicious activity and perform distributed denial of service attacks. Traditional protection mechanisms rely on host based detection of viruses. These systems are failing due to the rapid increase in the number of vulnerable hosts and attacks that easily bypass detection mechanisms. This paper pro-poses moving protection from the individual hosts to the Internet Ser-vice Provider (ISP), allowing for the detection and prevention of botnet traffic. DNS traffic inspection allows for the development of a lightweight and accurate classifier that has little or no effect on network perfor-mance. By preventing botnet activity at the ISP level, it is hoped that the threat of botnets can largely be mitigated.

- Description: Research has shown that fuzz-testing is an effective means of increasing the quality and security of software and systems. This project proposes the im-plementation of a testing framework based on numerous fuzz-testing tech-niques. The framework will allow a user to detect errors in applications and locate critical areas in the applications that are responsible for the detected errors. The aim is to provide an all-encompassing testing framework that will allow a developer to quickly and effectively deploy fuzz tests on an applica-tion and ensure a higher level of quality control before deployment.

High Speed Lexical Classification of Malicious URLs

- Description: It has been shown in recent research that it is possible to identify malicious URLs through lexi-cal analysis of their URL structures alone. Lightweight algorithms are defined as methods by which URLs are analyzed that do not use external sources of information such as WHOIS lookups, blacklist lookups and content analysis. These parameters include URL length, number of delimiters as well as the number of traversals through the directory structure and are used throughout much of the research in the paradigm of lightweight classification. Methods which include external sources of information are often called fully featured classifications and have been shown to be only slightly more effective than a purely lexical analysis when considering both false-positives and falsenegatives. This distinction allows these algorithms to be run client side without the introduction of additional latency, but still providing a high level of accuracy through the use of modern techniques in training classifiers. Both AROW and CW classifier update methods will be used as prototype implementations and their effectiveness will be com-pared to fully featured analysis results. These methods are selected because they are able to train on any labeled data, including instances in which their prediction is correct, allowing them to build a confidence in specific lexical features.

- Description: Efficient utilization of hostile network traffic for visualization and defen-sive purposes require near real-time availability of such data. Hostile or malicious traffic was obtained through the use of network telescopes and honeypots, as they are effective at capturing mostly illegitimate and nefarious traffic. The data is then exposed in near real-time through a messaging framework and visualized with the help of a geolocation based visualization tool. Defensive applications with regards to hostile network traffic are explored; these include the dynamic quarantine of malicious hosts internal to a network and the egress filtering of denial of service traffic originating from inside a network.
