....network analysis purposes, and not specific to intrusion detection. We apply the frequent episodes program to both normal connection data and intrusion data, and compare the resulting patterns to find the intrusion only patterns. The details of the pattern comparison algorithm is described in [12]. Briefly, since the number of patterns may be very large and there are rarely exactly matched patterns from two data sets, this heuristic algorithm considers two episodes related to two different sets of axis features as more different, and outputs (the user specified) top percentage of the most ....

Example Intrusion Pattern in [12], to support the iterative procedure of pattern mining and comparison, feature construction from patterns, and model building and evaluation. In each iteration, we choose a different data mining strategy regarding the choices of axis and reference features. These choices are limited among the ....

....http, f lag = S0) # (service = http, f lag = S0) Contrast with normal data: no patterns with f lag = S0. We have developed an automatic technique for comparing and identifying intrusion only patterns from an aggregate set of normal patterns and a set of patterns from intrusion audit data [LSM99b] That is, the pattern analysis tasks described above can be automated. In [LSM99a] we described an algorithm for constructing temporal and statistical features from the identified intrusion only patterns. We reported that using this feature construction process, the resultant RIPPER classifier ....
