Creating and recognizing automatically the behavior profile of a user from the commands in a command line interface. Computer user behavior is represented as a sequence of UNIX commands. This sequence is transformed into a distribution of relevant subsequences in order to find out a profile that defines its behavior .The existing system novel evolving user behavior classifier is based on Evolving Fuzzy Systems and it takes into account the fact that the behavior of any user is not fixed, but is rather changing. Timely detection of computer system with intrusion is a problem that is receiving increasing attention.
