This document summarizes research on detecting HTTP botnets. It provides an abstract describing botnets and the challenges of detecting HTTP-based botnet communications. It then summarizes 5 research papers on HTTP botnet detection techniques. Each paper is summarized including the methodology used. Methodologies discussed include using neural networks, data mining algorithms like Apriori, density-based clustering algorithms, and machine learning classifiers like decision trees. The document concludes that both signature-based and behavior-based techniques can be used to detect HTTP botnets by focusing on interrupting stages of the botnet lifecycle.
