  Intrusion Detection is one of major threats for organization. The approach of
intrusion detection using text processing has been one of research interests
which is gaining significant importance from researchers. In text mining based
approach for intrusion detection, system calls serve as source for mining and
predicting possibility of intrusion or attack. When an application runs, there
might be several system calls which are initiated in the background. These
system calls form the strong basis and the deciding factor for intrusion
detection. In this paper, we mainly discuss the approach for intrusion
detection by designing a distance measure which is designed by taking into
consideration the conventional Gaussian function and modified to suit the need
for similarity function. A Framework for intrusion detection is also discussed
as part of this research.
