abstract = "The paper proposes a multiobjective approach to the
problem of malicious network traffic classification,
with specificity and sensitivity criteria as objective
functions for the problem. The multiobjective version
of Gene Expression Programming (GEP) called moGEP is
proposed and applied to find proper classifiers in the
multiobjective search space. The purpose of the
classifiers is to discriminate information about the
network traffic obtained from Idiotypic Network-based
Intrusion Detection System (INIDS), transformed into
time series. The proposed approach is validated using
the network traffic simulator ns2. Classifiers of high
accuracy are obtained and their diversity offers
interesting possibilities to the domain of network
security.",
