Using Constraints for Intrusion Detection: The NeMODe System [chapter]

Pedro Salgueiro, Daniel Diaz, Isabel Brito, Salvador Abreu
2011 Lecture Notes in Computer Science  
In this work we present NeMODe a declarative system for Computer Network Intrusion detection which provides a declarative Domain Specific Language for describing computer network intrusion signatures that  ...  relies on Constraint Programming (CP) methodologies to find those intrusions.  ...  The IBM QS21 dual-Cell/BE blades used in this work were donated by IBM Corporation, in the context of a SUR (Shared University Research) grant awarded to Universidade de Évora and CENTRIA.  ...

Modelling distributed network attacks with constraints

Pedro Salgueiro, Salvador Abreu
2013 International Journal of Bio-Inspired Computation (IJBIC)  
NeMODe is a declarative system for computer network intrusion detection, providing a declarative domain specific language for describing network intrusion signatures which can span several network packets  ...  to perform the detection of the specific intrusions.  ...  Such task can be accomplished by network intrusion detection system (IDS) e.g., Snort (Roesch, 1999) .  ...

isDSL - A Domain Specific Language for Intrusion Signature Declaration

Kanin Chotvorrarak, Yachai Limpiyakorn
2013 Interdisciplinary Research Theory and Technology   unpublished
This paper presents a signature-based network intrusion detection system. The intrusions are detected using their signatures defined as a set of rules contained in DSL scripts.  ...  Moreover, the use of genetic algorithm would reduce the number of packet combinations being investigated for signs of the intrusions.  ...  In literature, the NeMODe system [6] is an example of network intrusion detection systems that provides a declarative and expressive domain specific language for describing intrusion signatures that  ...
