Using CLIPS to detect network intrusions

Ver documento

Detalhes bibliográficos
Resumo:This paper shows how to build a network intrusion detection system by slightly modifying NASA's CLIPS source code, introducing features such as single and multiple string pattern matching, certainty factors and time-stamp operators. Several Snort functions and plugins were adapted and used for packet decoding and preprocessing to provide the basic requirements for such a system. The integration of CLIPS and Snort features allows the specification of complex stateful network intrusion detection heuristics which can model abstract attack scenarios. The results show that CLIPS can be useful to follow and correlate intruder activities by monitoring network traffic.
