Honeypots are ﬂexible security tools for gathering artefacts associated with a variety of Internet attack activities. While existing work on honeypot trafﬁc analysis focuses mainly on identifying existing attacks, this paper describes a technique for detecting new attacks based on principal component analysis. The proposed technique requires no prior knowledge of attack types and has low computational requirements that makes it suitable for online detection systems. Our method of detecting new attacks is based on measuring changes in the residual space using square prediction error (SPE) statistics. When attack vectors are projected onto the residual space, attacks that are not presented by the main hyperspace will create new directions with high SPE values. We demonstrate the usefulness of our technique by using real trafﬁc data from the Leurré.com project, a world-wide deployment of low-interaction honeypots, where several examples of new trafﬁc detected by the system are illustrated.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
