Among these are the EMERALD project at SRI [11] work by Dain and Cunningham at Lincoln Labs [3] the Common Intrusion Detection Framework (CIDF) [6], and the Internet Engineering Task Force s Intrusion Detection Exchange Format (IDEF) 4, 5] 3 Data Refinement and Knowledge Creation The goal of this work is not to improve upon the methods currently used in intrusion detection, but rather to develop methods for more e#ectively analyzing the ....

....triggered IDS rules many times over could be reduced to single events. In the object refinement stage, data is normalized and described in a common format. This includes time synchronization and conversion to a common description format such as the DARPA Common Intrusion Detection Framework (CIDF)[6, 7] or the Internet Engineering Task Force s Intrusion Detection Exchange Protocol (IDXP) 5, 4] In these formats, intrusion events are described as an object that has a set of attributes. We are concerned with features such as the time of the event, internet protocol (IP) source and destination ....

....level attacks are unrelated or do not compromise the system, by sending alerts only when events correlate, we can significantly reduce the number of false positives. As part of the UC Davis Global Guard project we are designing a correlating IDS that incorporates our model and the output of CIDF [8] compliant intrusion detection systems as inputs to our system. CISL[4] reports are wrapped with JIGSAW concepts that describe the capabilities the detected intrusion provides. In this way we can interface to any compliant IDS. For example, port scans provide capabilities about what an attacker ....

The lack of such a capability can result in inefficient communication between IDSs. If the sending IDSs send all ....

In describing a framework for communications between intrusion detection systems, Kahn, et al.

Con guration interoperability, which refers to the ability of two systems to discover one another and communicate data back and forth. 2. The ability to parse the data being ....

This survey is indeed intended to be thorough, with the surveyed systems described in some detail and classi ed according to a number of interesting features. There are several ideas in the literature about how to perform intrusion detection, such as [5, 16, 27, 44] to name a few. These have not been covered since the emphasis here is on intrusion detection systems. We wish to survey substantial research e orts that have generated a prototype that can be studied, both quantitatively, and qualitatively. No slight towards the systems not covered, or its ....
