Abstract

In this paper we analyze some intrusion detection strategies proposed in the literature and we show that they represent the various facets of a well known formal languages problem: computing the distance between a string x and a language L. In particular, the main differences among the various approaches adopted for building intrusion detection systems can be reduced to the characteristics of the language L and to the notion of distance adopted. As a further contribution we will also show that from the computational point of view all these strategies are equivalent and they are amenable to efficient parallelization.
