Abstract
An Intrusion Detection System (IDS) is a program that
analyses what happens or has happened during an
execution and tries to find indications that the
computer has been misused. A Distributed IDS (DIDS)
consists of several IDS over a large network (s), all
of which communicate with each other, or with a central
server that facilitates advanced network monitoring. In
a distributed environment, DIDS are implemented using
co-operative intelligent agents distributed across the
network(s). This paper evaluates three fuzzy rule-based
classifiers to detect intrusions in a network. Results
are then compared with other machine learning
techniques like decision trees, support vector machines
and linear genetic programming. Further, we modelled
Distributed Soft Computing-based IDS (D-SCIDS) as a
combination of different classifiers to model
lightweight and more accurate (heavy weight) IDS.
Empirical results clearly show that soft computing
approach could play a major role for intrusion
detection.
