Abstract
Cyber criminals compromise Integriry. Availability and Confidentiality of network resources in
cyber space and cause remote class intrusions such as U2R, R2L, DoS and probe/scan system
attacks .To handle these intrusions, Cyber Security uses three audit and monitoring systems
namely Intrusion Prevention Sy.stems (IPS), Intrusion Detection Systems (IDS). Intrusion
Detection System (IDS) monitors only inbound traffic which is insufficient to prevent botnet
systems. A system to monitor outbound traffic is named as Extrusion Detection System (EDS).
Therefore a hybrid system should he designed to handle both inbound and outbound traffic.
Due to the increased false alarms preventive systems do not suite to an organizational network.
The goal o f this paper is to devise a taxonomy for cyber security and study the existing methods
of Intrusion and Extrusion Detection systems based on three primary characteristics. The
metrics used to evaluate IDS and EDS are also presented.
