279New Unknown Attack Detection with the Neural Network–Based IDS
In Table 11.2, the accuracy of detection for each type of the new attacks from the test data set
was presented. It could be noticed that for 17 new attacks only two were classied with a detection
rate that equals 100%.
11.6.2 phaSe 2
As we noticed in the rst phase, the SVM network better classied a new pattern. That’s why, for
the second phase of the investigation, we decided to use only this neural network’s architecture.
The results of the tests are presented in Table 11.3 (new normal trafc) and Table 11.4 (new attacks).
The rst row of each table corresponds to the situation ...
