Abstract-During the last decade, anomaly detection has attracted the attention of many researchers to overcome the weakness of signature-based IDSs in detecting novel attacks, and KDDCUP'99 is the mostly widely used data set for the evaluation of these systems. Having conducted an statistical analysis on this data set, we found two important issues which highly affects the performance of evaluated systems, and results in a very poor evaluation of anomaly detection approaches. To solve these issues, we have proposed a new data set, NSL-KDD, which consists of selected records of the complete KDD data set and does not suffer from any of mentioned shortcomings.
The goals of the Springer International Series on ADVANCES IN INFORMATION SECURITY are, one, to establish the state of the art of, and set the course for future research in information security and, two, to serve as a central reference source for advanced and timely topics in information security research and development. The scope of this series includes all aspects of computer and network security and related areas such as fault tolerance and software assurance.
ADVANCES IN INFORMATION SECURITY aims to publish thorough and cohesiveoverviews of specific topics in information security, as well as works that are larger in scope or that contain more detailed background information than can be accommodated in shorter survey articles. The series also serves as a forum for topics that may not have reached a level of maturity to warrant a comprehensive textbook treatment.Researchers, as well as developers, are encouraged to contact Professor Sushil Jajodia with ideas for books under this series.
Botnets are networks of compromised computers infected with malicious code that can be controlled remotely under a common command and control (C&C) channel. Recognized as one the most serious security threats on current Internet infrastructure, advanced botnets are hidden not only in existing well known network applications (e.g. IRC, HTTP, or Peer-to-Peer) but also in some unknown or novel (creative) applications, which makes the botnet detection a challenging problem. Most current attempts for detecting botnets are to examine traffic content for bot signatures on selected network links or by setting up honeypots. In this paper, we propose a new hierarchical framework to automatically discover botnets on a large-scale WiFi ISP network, in which we first classify the network traffic into different application communities by using payload signatures and a novel cross-association clustering algorithm, and then on each obtained application community, we analyze the temporal-frequent characteristics of flows that lead to the differentiation of malicious channels created by bots from normal traffic generated by human beings. We evaluate our approach with about 100 million flows collected over three consecutive days on a large-scale WiFi ISP network and results show the proposed approach successfully detects two types of botnet application flows (i.e. Blackenergy HTTP bot and Kaiten IRC bot) from about 100 million flows with a high detection rate and an acceptable low false alarm rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
