Over the past decade, intrusion detection systems (IDS) have improved steadily in the efficiency and effectiveness with which they detect intrusive activity. This is particularly true with signature-based IDS due to progress with intrusion analysis and intrusion signature specification. At the same time system complexity, overall numbers of bugs and security vulnerabilities have been on the increase. This has led to the recognition that in order to operate over the entire attack space, multiple heterogeneous IDS must be used, which need to interoperate with one another, and possibly also with other components of system security. We describe our research into developing algorithms for attack signature matching for detecting multistage attacks manifested by alerts from heterogeneous IDS. It describes also the testing and preliminary results of that research, and the administrator interface used to analyze the alerts produced by the tests and the results of signature matching.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® 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.
