Survey of Intrusion Detection Research

Rapport, 2002

The literature holds a great deal of research in the intrusion detection area. Much of this describes the design and implementation of specific intrusion detection systems. While the main focus has been the study of different detection algorithms and methods, there are a number of other issues that are of equal importance to make these systems function well in practice. I believe that the reason that the commercial market does not use many of the ideas described is that there are still too many unresolved issues. This survey focuses on presenting the different issues that must be addressed to build fully functional and practically usable intrusion detection systems (IDSs). It points out the state of the art in each area and suggests important open research issues.
