Abstract:

The increment of intrusions and bad uses in the computer systems and internal networks of a great number of companies, it has caused an increase in the concern for the computer security. For some time one comes applying measures based on fire walls and in Intrusion Detection Systems (IDS). In this document we present an alternative to the problem of the IDS based on rules, using two different neural network, a multi-layer perceptron, and a self organizative map. They are carried out a series of experiments and the results are shown that they have been better than other found in the literature.
