There is currently a need for an up-to-date, thorough survey of the field of intrusion detection. This paper presents
such a sun’ey of the important research on intrusion detection systems to date. It should be noted that the main focus
of this survey is intrusion detection systems, in other words major research efforts that have resulted in prototypes
that can be studied both quantitatively and qualitatively. We touched a number of open questions related to
intrusion detection. However, there are a number of unresolved issues regarding the scope of analysis that an IDS
performs and the interoperability of intrusion detection systems
