Conceptual Integration of Flow-Based and Packet-Based Network Intrusion Detection [chapter]

Gregor Schaffrath, Burkhard Stiller
2008 Lecture Notes in Computer Science  
Since network link speeds and traffic volume grew over the last years, payload-based analysis became difficult, leading to the development of alternative approaches for flowbased analysis.  ...  This work analyses these drawbacks in order to develop a conceptual framework for hybrid approaches, integrating the two concepts in a fashion to compensate for their respective weaknesses proposed.  ...  The work of Fabian Hensel in support of first steps for developing the evaluation scenarios and implementation environments is acknowledged.  ...
